Description

WO 96/40880 PCT/US96/11187 RECOMBINANT FOWLPOX VIRUSES AND USES THEREOF Within this application several publications are referenced by arabic numerals within parentheses. Full citations for these references may be found at the end of the specification immediately preceding the claims. The disclosures of these publications in their entireties are hereby incorporated by reference into this application in order to more fully describe the state of the art to which this invention pertains.
BACKGROUND OF THE INVENTION The present invention relates to recombinant fowlpox virus useful in live vaccine to protect fowl against Newcastle disease virus and fowlpox virus.
The ability to isolate DNA and clone this isolated DNA into bacterial plasmids has greatly expanded the approaches available to make viral vaccines. The method used to make the present invention involve modifying cloned DNA sequences by insertions, deletions and single or multiple base changes. The modified DNA is then inserted into a viral genome, and the resulting virus may then be used in a vaccine to elicit an immune response in a host animal and provide protection to the animal against disease.
Fowlpox virus (FPV) is a member of the poxviridiae family of viruses. There are two subfamilies in this classification, and they are differentiated based upon WO 96/40880 PCT/US96/11187 -2the host range (vertebrate or invertebrate) of the virus.
Among the vertebrate poxviruses, there is serological cross reactivity to group specific antigens that has aided in classification of the viruses into six genera, and FPV has been placed in the avipoxvirus genera along with seven additional poxviruses that primarily infect birds. In general, poxviruses are the largest of the animal viruses and can be visualized with the light microscope. Under the electron microscope, the virus takes on a biscuit like or oval shaped appearance. The principal chemical components of the poxviruses are protein (90% by weight), deoxyribonucleic acid (DNA) and lipid but in FPV the lipid component is -1/3 of the dry weight. Polyacrylamide gel electrophoresis (PAGE) of solubilized virions indicates that there are >100 different proteins associated with the viruses that include: structural polypeptides, enzymes associated with translation of messenger ribonucleic acid (mRNA), enzymes involved in RNA synthesis, and enzymes associated with DNA replication. The genome of poxviruses consists double-stranded DNA that varies in base composition (32% G+C to 64% G+C) and length (140 kilobasepairs [kb] to 280 kb for FPV) depending upon individual virus. The complete nucleotide sequence of the vaccina virus (VV) genome has recently been determined, and most of the essential genes have been found to lie within the highly conserved middle region of the genome while nonessential functions seem to map nearer to the termini of the DNA.
The poxviruses are unique in their propensity to replicate within the cytoplasmic space of the infected cell, and in the case of VV, mature virus particles are moved out of the assembly areas and into the periphery of the cell where additional membrane encapsulation occurs.
With FPV, the assembled viral particles become associated with a dense viral-derived protein matrix that occludes the virus in the form of cellular inclusions that may help protect the virion from lytic activities. Depending WO 96/40880 PCT/US96/11187 -3upon the specific poxvirus and strain (from 1% to 30% of different mature VV strains) varying levels of mature virus can be found extracellularly, but the majority of the virus population remains associated with the cell at the end of the growth cycle.
Fowlpox is unique throughout the world, but because its host-range is limited to birds it is not considered to be a public health hazard. All chickens can be infected by the virus with a resulting decline in the growth rate of the bird and temporary decreases in egg production.
Usually, transmission of FPV occurs through physical contact of injured skin, but there are reports that the virus is also transmitted via arthropod vectors. After an incubation period of four to ten days, the disease is typically manifested in the following ways: skin lesions in non-feathered areas, lesions of the nasal passages, and lesions of the mouth. A normal FPV infection usually lasts three to four weeks, and afterward the bird is conferred life-long immunity to the disease.
Currently, conventionally derived FPV vaccines are being used in commercial settings to provide protection to chickens and turkeys. Typically, the vaccine viruses are attenuated by serial passage in cell culture selecting for strains that have altered growth and/or virulence properties. The modified live vaccine is prepared by growth in vitro in chicken embryo fibroblast cells or by growth on the chorioallantoic membrane of the chicken embryo. The vaccine virus is given to birds subcutaneously.
The present invention concerns the use of FPV as a vector for the delivery of specific vaccine antigens to poultry.
The idea of using live viruses as delivery systems for antigens (vectoring) has a long history that is associated with introduction of the first live viral WO96/40880 PCTIUS96/11187 -4vaccines. The antigens that were delivered were not foreign but were naturally expressed by the live virus in the vaccine. The use of viruses to deliver foreign antigens in the modern sense became obvious with the recombinant DNA studies. The vaccinia virus was the vector and various antigens from other disease causing pathogens were the foreign antigens, and the vaccine was created by genetic engineering. While the concept became obvious with these disclosures, what was not obvious were the answers to more practical questions concerning what makes the best candidate viral vector and what constitutes the best foreign gene or gene to deliver. In answering these questions, details of the pathogenicity, site of replication or growth, the kind of elicited immune response, expression levels for the virus and foreign gene of interest (GOI), its suitability for genetic engineering, its probability of being licensed by regulatory agencies, etc. are all factors in the configuration. The prior art does not teach these questions of utility.
The presently preferred method for creating recombinant poxviruses uses a plasmid of bacterial origin that contains at least one cassette consisting of a poxvirus promoter followed by the gene of interest. The cassette(s) is flanked by poxvirus genomic DNA sequences that direct the gene of interest to the corresponding homologous nonessential region of the viral genome by homologous recombination. Cells are initially infected with the wild-type virus, and shortly thereafter the plasmid DNA is introduced into the infected cells. Since poxviruses have their own RNA polymerase and transcriptional apparatus, it is necessary that the gene of interest be regulated by a promoter of poxvirus origin. There are three characteristic poxvirus promoters that are differentiated based upon their temporal regulation of gene expression relative to the WO96/40880 PCT/US96/11187 infective cycle of the virus: early, intermediate and late expression. Each promoter type can be identified by a typical consensus sequence that is -30 bp in length and specific to each promoter type. In vaccinia virus, some viral genes are regulated by tandem early/late promoters that can be used by the virus to continually express the downstream gene throughout the infective cycle.
It is generally agreed that poxviruses contain nonessential regions of DNA in various parts of the genome, and that modifications of these regions can either attenuate the virus, leading to a non-pathogenic strain from which a vaccine may be derived, or give rise to genomic instabilities that yield mixed populations of virus. The degree of attenuation of the virus is important to the utility of the virus as a vaccine.
Insertions or deletions which cause too much attenuation or genetic deletions which cause too much attenuation or genetic instability of the virus will result in a vaccine that fails to elicit an adequate immune response.
Although several examples of deletions/insertions are known for poxviruses, the appropriate configuration is not readily apparent.
Thus far, gene expression from foreign genes of interest have been inserted into the genome of poxviruses has been obtained for five different pox viruses: vaccinia, canary pox, pigeon pox, raccoon pox and fowlpox. Vaccinia virus is the classically studied poxvirus, and it has been used extensively to vector foreign genes of interest; it is the subject of U.S. Patents 4,603,112 and 4,722,848.
Raccoon pox (Esposito, et al., 1988) and Canary pox (Taylor, et al., 1991) have bene used to express antigens from the rabies virus. More recently, FPV has been used to vector a number of different foreign gene of interest, and is the subject of patent applications (EPA 0 284 416, PCT WO 89/03429, PCT WO 89/12684, PCT WO 91/02072, PCT WO WO 96/40880 PCT/US96/11187 -6- 89/03879, PCT etc.). However, these publications do not teach the vectored antigen configuration, the FPV insertion sites, or the promoter sequences and the arrangement of the present invention.
A foreign gene of interest targeted for insertion into the genome of FPV can be obtained from any pathogenic organism of interest. Typically, the gene of interest will be derived from pathogens that cause diseases in poultry that have an economic impact on the poultry industry. The genes can be derived from organisms for which there are existing vaccines, and because of the novel advantages of the vectoring technology the FPV derived vaccines will be superior. Also, the gene of interest may be derived from pathogens for which thee is currently no vaccine but where there is a requirement for control of the disease. Typically, the gene of interest encodes immunogenic polypeptides of the pathogen, and may represent surface proteins, secreted proteins and structural proteins.
One relevant avian pathogen that is a target for FPV vectoring in the present invention is Infectious Laryngotracheitis virus (ILT). ILT is a member of the herpesviridiae family, and this pathogen causes an acute disease of chickens which is characterized by respiratory depression, gasping and expectoration of bloody exudate.
Viral replication is limited to cells of the respiratory tract, where in the trachea the infection gives rise to tissue erosion and hemorrhage. In chickens, no drug has been effective in reducing the degree of lesion formation or in decreasing clinical signs. Vaccination of birds with various modified forms of the ILT virus derived by cell passage and/or tedious regimes of administration have conferred acceptable protection in susceptible chickens. Because of the degree of attenuation of current ILT vaccines, care must be taken to assure that WO 96/40880 PCT/US96/11187 -7the correct level of virus is maintained; enough to provide protection, but not enough to cause disease in the flock.
An additional target for the FPV vectoring approach is Newcastle disease, an infectious, highly contagious and debilitating disease that is caused by the Newcastle disease virus (NDV), a single-stranded RNA virus of the paramyxovirus family. The various pathotypes of NDV (velongic, mesogenic, lentogenic) differ with regard to the severity of the disease, the specificity and symptoms, but most types seem to infect the respiratory system and the nervous system. NDV primarily infects chickens, turkeys and other avian species. Historically, vaccination has been used to prevent disease, but because of maternal antibody interference, life-span of the bird and route of administration, the producer needs to adapt immunization protocols to fit specific needs.
Marek's disease of poultry is a lymphoproliferative tumor producing disease of poultry that primarily affects the peripheral nervous system and other visceral tissues and organs. Marek's disease exists in poultry producing countries throughout the world, and is an additional target described by the present invention for a FPV-based vectored vaccine. The causative agent of Marek's disease is a cell associated gammaherpesvirus that has been designated as Marek's disease virus (MDV). Three classes of viruses have been developed as conventional vaccines for protecting chickens against Marek's disease: attenuated serotype 1 MDV, herpesvirus of turkeys (HVT), and naturally avirulent serotype 2 isolates of MDV.
Protection obtained with these vaccines is principally directed toward the tumorigenic aspect of the disease.
The occurrence of excessive Marek's disease losses in such conventionally vaccinated flocks has led to the requirement for forming admixtures of the various vaccine WO 96/40880 PCT/US96/11187 -8types. Such polyvalent vaccines while generally ore effective in disease control, complicate the vaccine regime.

WO 96/40880 PCT/US96/11187 -22- MATERIAL AND METHODS PREPARATION OF FOWLPOX VIRUS STOCK SAMPLES. Fowlpox virus samples were prepared by infecting chicken embryo fibroblast (CEF) cells at a multiplicity of infection of 0.01 PFU/cell in a 1:1 mixture of HAM's F10 medium and Medium 199 (F10/199) containing 2 mM glutamine and antibiotics (referred to as CEF negative medium). Prior to infection, the cell monolayers were washed once with CEF negative medium to remove fetal bovine serum. The FPV contained in the initial inoculum (0.5 ml for 10 cm plate; 10 ml for T175 cm flask) was allowed to absorb onto the cell monolayer for two hours, being redistributed every half hour. After this period, the original inoculum was brought up to an appropriate final volume by the addition of complete CEF medium (CEF negative medium plus 2% fetal bovine serum). The plates were incubated at 37 0 C in 5% CO 2 until cytopathic effect was complete. The medium and cells were harvested, frozen at -70 0 C, thawed and dispensed into 1.0 ml vials and refrozen at -70 0 C. Virus titers typically range between 10' and 107 PFU/ml.
PREPARATION OF FPV DNA. For fowlpox virus DNA isolation, a confluent monolayer of CEF cells in a T175 cm 2 flask was infected at a multiplicity of 0.1 and incubated 4-6 days until the cells were showing 100% cytopathic effect. The infected cells were harvested by scraping into the medium and centrifuging at 3000 rpm for 5 minutes in a clinical centrifuge. The medium was decanted, and the cell pellet was gently resuspended in 1.0 ml PBS (per T175) and subjected to two successive freeze-thaws (-70 0 C to 37°C).
After the last thaw, the cells (on ice) were sonicated two times for 30 seconds each with 45 seconds cooling time in between. Cellular debris was removed by centrifuging (Sorvall RC-5B Superspeed Centrifuge) at 3000 rpm for 5 minutes in an HB4 rotor at 4°C. FPV WO 96/40880 PCT/US96/11187 -23virions, present in the supernatant, were pelleted by centrifugation at 15,000 rpm for 20 minutes at 4°C in a SS34 rotor (Sorvall) and resuspended in 10mM Tris (pH This fraction was then layered onto a 36% sucrose gradient (w/v in 10 mM Tris pH 7.5) and centrifuged (Beckman L8-70M Ultracentrifuge) at 18,000 rpm for minutes in a SW41 rotor at 4°C. The virion pellet was resuspended in 1.0 ml of 10 mM Tris pH 7.5 and sonicated on ice for 30 seconds. This fraction was layered onto a 20% to 50% continuous sucrose gradient and centrifuged at 16,000 rpm for 60 minutes in a SW41 rotor at 4°C. The FPV virion band located about three quarters down the gradient was harvested, diluted with 20% sucrose and pelleted by centrifugation at 18,000 rpm for 60 minutes in a SW41 rotor at 4°C. The resultant pellet was then washed once with 10 mM Tris pH 7.5 to remove traces of sucrose and finally resuspended in 10mM Tris pH 7.5. FPV DNA was then extracted from the purified virions by lysis (four hours at 60°C) following the addition of EDTA, SDS, and proteinase K to final concentrations of 20 mM, and 0.5 mf/ml, respectively. After digestion, three phenol-chloroform extractions were conducted and the sample precipitated by the addition of two volumes of absolute ethanol and incubated at -20 0 C for 30 minutes.
The sample was then centrifuged in an Eppendorf minifuge for five minutes at full speed. The supernatant was decanted, and the pellet air dried and rehydrated in 0.01 M Tris pH 7.5, 1mM EDTA at 4 0
C.
MOLECULAR BIOLOGICAL TECHNIQUES. Techniques for the manipulation of bacteria and DNA, including such procedures as digestion with restriction endonucleases, gel electrophoresis, extraction of DNA from gels, ligation, phosphorylation with kinase, treatment with phosphatase, growth of bacterial cultures, transformation of bacteria with DNA, and other molecular biological methods are described by Maniatis et al (1982) and I- WO 96/40880 PCT/US96/11187 -24- Sambrook et al (1989). Except as noted, these were used with minor variation.
DNA SEQUENCING. Sequencing was performed using the BRL Sequenase Kit and 3 "S-dATP (NEN). Reactions using both the dGTP mixes and the dITP mixes were performed to clarify areas of compression. Alternatively, compressed areas were resolved on formamide gels. Templates were double-stranded plasmid subclones or single stranded M13 subclones, and primers were either made to the vector just outside the insert to be sequenced, or to previously obtained sequence. Sequence obtained was assembled and compared using Dnastar software. Manipulation and comparison of sequences obtained was performed with Superclone and Supersee programs from Coral Software.
STRATEGY FOR THE CONSTRUCTION OF SYNTHETIC POX VIRAL PROMOTERS. For recombinant fowlpox vectors synthetic pox promoters offer several advantages including the ability to control the strength and timing of foreign gene expression. We chose to design four promoter cassettes EP1 (SEQ ID NO:8, LP1 (SEQ ID NO:9), EP2 (SEQ ID and LP2 (SEQ ID NO:11) based on promoters that have been defined in the vaccinia virus (Bertholet et al. 1986, Davidson and Moss, 1989a, and Davidson and Moss, 1989b).
Each cassette was designed to contain the DNA sequences defined in vaccina flanked by restriction sites which could be used to combine the cassettes in any order or combination. Initiator methionines were also designed into each cassette such that inframe fusions could be made at either EcoRI or BamHi sites. A set of translational stop codons in all three reading frames and an early transcriptional termination signal (Earl, et al., 1990) was also engineered downstream of the inframe fusion site. DNA encoding each cassette was synthesized according to standard techniques and cloned into the appropriate homology vectors.
1. WO 96/40880 PCT/US96/11187 cDNA CLONING PROCEDURE. cDNA cloning refers to the methods used to convert RNA molecules into DNA molecules following state of the art procedures. Applicants' methods are described in (Gubler and Hoffman, 1983).
Bethesda Research Laboratories (Gaithersburg, MD) have designed a cDNA Cloning Kit that is very similar to the procedures used by applicants, and contains a set of reagents and protocols that may be used to duplicate our results.
For cloning virus mRNA species, a host cell line sensitive to infection by the virus was infected at 5-10 plaque forming units per cell. When cytopathic effect was evident, but before total destruction, the medium was removed and the cells were lysed in 10 mls lysis buffer (4 M guanidine thiocyanate, 0.1% antifoam A, 25 mM sodium citrate pH 7.0, 0.5% N-lauroyl sarcosine, 0.1 M betamercaptoethanol). The cell lysate was poured into a sterilized Dounce homogenizer and homogenized on ice 8-10 times until the solution was homogenous. For RNA purification, 8mls of cell lysate were gently layered over 3.5 mls of CsCl solution (5.7 M CsCl, 25 mM sodium citrate pH 7.0) in a Beckman SW41 centrifuge tube. The samples were centrifuged for 18 hrs at 20 0 C at 36000 rpm in a Beckman SW41 rotor. The tubes were put on ice and the supernatants from the tubes were carefully removed by aspiration to leave the RNA pellet undisturbed. The pellet was resuspended in 400 pl glass distilled water, and 2.6 mls of guanidine solution (7.5 M guanidine-HCl, 25 mM sodium citrate pH 7.0, 5 mM dithiothreitol) were added. Then 0.37 volumes of 1 M acetic acid were added, followed by 0.75 volumes of cold ethanol and the sample was put at -20 0 C for 18 hrs to precipitate RNA. The precipitate was collected by centrifugation in a Sorvall centrifuge for 10 min at 4 0 C at 10000 rpm in an SS34 rotor. The pellet was dissolved in 1.0 ml distilled water, recentrifuged at 13000 rpm, and the supernatant WO 96/40880 PCT/US96/11187 -26saved. RNA was re-extracted from the pellet 2 more times as above with 0.5 ml distilled water, and the supernatants were pooled. A 0.1 volume of 2 M potassium acetate solution was added to the sample followed by 2 volumes of cold ethanol and the sample was put at for 18 hrs. The precipitated RNA was collected by centrifugation in the SS34 rotor at 4°C for 10 min at 10000 rpm. The pellet was dissolved in 1 ml distilled water and the concentration taken by adsorption at A260/280. The RNA was stored at -70 0
C.
mRNA containing polyadenylate tails (poly-A) was selected using oligo-dT cellulose (Pharmacia #27 5543-0). Three mg of total RNA was boiled and chilled and applied to a 100 mg oligo-dT cellulose column in binding buffer (0.1 M Tris pH 7.5, 0.5 M LiCl, 5 mM EDTA pH 8.0, 0.1% lithium dodecyl sulfate). The retained poly-A+ RNA was eluted from the column with elution buffer (5 mM Tris pH 7.5, 1 mM EDTA pH 8.0, 0.1% sodium dodecyl sulfate). This mRNA was reapplied to an oligo-dT column in binding buffer and eluted again in elution buffer. The sample was precipitated with 200 mM sodium acetate and 2 volumes cold ethanol at -20 0 C for 18 hrs. The RNA was resuspended in 50 pl distilled water.
Ten Ag poly-A+ RNA was denatured in 20 mM methyl mercury hydroxide for 6 min at 22 0 C. 3-mercaptoethanol was added to 75 mM and the sample was incubated for 5 min at 22°C.
The reaction mixture for first strand cDNA synthesis in 0.25 ml contained 1 Ag oligo-dT primer (P-L Biochemicals) or 1 fg synthetic primer, 28 units placental ribonuclease inhibitor (Bethesda Research Labs #5518SA), 100 mM Tris pH 8.3, 140 mM KC1, 10 mM MgC12, 0.8 mM dATP, dCTP, dGTP, and dTTP (Pharmacia), 100 microcuries 32Plabeled dCTP (New England Nuclear #NEG-013H), and 180 units AMV reverse transcriptase (Molecular Genetics Resources #MG 101). The reaction was incubated at 42°C WO 96/40880 PCT/US96/11187 -27for 90 min, and then was terminated with 20 mM EDTA pH The sample was extracted with an equal volume of phenol/chloroform and precipitated with 2 M ammonium acetate and 2 volumes of cold ethanol -20 0 C for 3 hrs. After precipitation and centrifugation, the pellet was dissolved in 100 jil distilled water. The sample was loaded onto a 15 ml G-100 Sephadex column (Pharmacia) in buffer (100 mM Tris pH 7.5, 1 mM EDTA pH 100 mM NaCI). The leading edge of the eluted DNA fractions were pooled, and DNA was concentrated by lyophilization until the volume was about 100 il, then the DNA was precipitated with ammonium acetate plus ethanol as above.
The entire first strand sample was used for second strand reaction which followed the Gubler and Hoffman (1983) method except that 50 ig/ml dNTP's, 5.4 units DNA polymerase I (Boerhinger Mannheim #642-711), and 100 units/ml E. coli DNA ligase (New England Biolabs #205) in a total volume of 50 microliters were used. After second strand synthesis, the cDNA was phenol/chloroform extracted and precipitated. The DNA was resuspended in pl distilled water, treated with 1 yg RNase A for min at 22 0 C, and electrophoresed through a 1% agarose gel (Sigma Type II agarose) in 40 mM Tris-acetate buffer pH 6.85. The gel was strained with ethidium bromide, and DNA in the expected size range was excised from the gel and electroeluted in 8 mM Tris-acetate pH 6.85.
Electroeluted DNA was lyophilized to about 100 microliters, and precipitated with ammonium acetate and ethanol as above. The DNA was resuspended in 20 Al water.
Oligo-dC tails were added to the DNA to facilitate cloning. The reaction contained the DNA, 100 mM potassium cacodylate pH 7.2, 0.2 mM dithiothreitol, 2 mM CaCl 2 80 jimoles dCTP, and 25 units terminal 1. WO 96/40880 PCT/US96/11187 -28deoxynucleotidyl transferase (Molecular Genetic Resources #S1001) in 50 Al. After 30 min at 37 0 C, the reaction was terminated with 10 mM EDTA, and the sample was phenol/chloroform extracted and precipitated as above.
The dC-tailed DNA sample was annealed to 200 ng plasmid vector pBR322 that contained oligo-dG tails (Bethesda Research Labs #5355 SA/SB) in 200 Al of 0.01 M Tris pH 0.1 M NaCl, 1 mM EDTA pH 8.0 at 65 0 C for 2 min and then 57 0 C for 2 hrs. Fresh competent E. coli DH-1 cells were prepared and transformed as described by Hanahan (1983) using half the annealed cDNA sample in twenty 200 pl aliquots of cells. Transformed cells were plated on L-broth agar plates plus 10 Ag/ml tetracycline. Colonies were screened for the presence of inserts into the ampicillin gene using Ampscreen\ (Bethesda Research Labs #5537 UA), and the positive colonies were picked for analysis.
HOMOLOGOUS RECOMBINATION PROCEDURE FOR GENERATING RECOMBINANT FPV. This method relies upon the homologous recombination between FPV DNA and the plasmid homology vector DNA which occurs in the tissue culture cells containing both FPV DNA and transfected plasmid homology vector. For homologous recombination to occur, monolayers of CEF cells are infected with S-FPV-001 (A mild fowlpox vaccine strain available as Bio-Pox' from Agri-Bio Corporation, Gainsville, Georgia) at a multiplicity of infection of 0.01 PFU/cell to introduce replicating FPV DNA synthesis) into the cells. The plasmid homology vector DNA is then transfected into these cells according to the "Infection-Transfection Procedure".
INFECTION-TRANSFECTION PROCEDURE. CEF cells in 6 cm plates (about 80% confluent) were infected with S-FPV-001 at a multiplicity of infection of 0.01 PFU/cell in CEF 1, o WO 96/40880 PCT/US96/11187 -29negative medium and incubated at 370C in a humidified
CO
2 incubator for five hours. The transfection procedure used is essentially that recommended for Lipofectin T M Reagent (BRL). Briefly, for each 6 cm plate, micrograms of plasmid DNA were diluted up to 100 microliters with H 2 0. Separately, 50 micrograms of Lipofectin M Reagent were diluted to 100 microliters with
H
2 0. The 100 microliters of diluted Lipofectin™ Reagent were added dropwise to the diluted plasmid DNA contained in a polystyrene, 5 ml, snap cap tube and mixed gently.
The mixture was then incubated for 15-20 minutes at room temperature. During this time, the virus inoculum was removed from the 6 cm plates and the cell monolayers washed once with CEF negative medium. Three mls of CEF negative medium were added to the plasmid DNA/lipofectin mixture and the contents pipetted onto the cell monolayer. Following overnight (about 16 hours) incubation at 37 0 C in a humidified 5% CO 2 incubator, the medium was removed and replaced with 5 ml CEF complete medium. The cells were incubated at 37°C in 5% CO 2 for 3- 7 days until cytopathic effect from the virus was 100%. Virus was harvested as described above for the preparation of virus stocks. This stock was referred to as a transfection stock and was subsequently screened for recombinant virus by the "Plaque Hybridization Procedure For Purifying Recombinant FPV".
PLAQUE HYBRIDIZATION PROCEDURE FOR PURIFYING RECOMBINANT FPV. CEF cell monolayers were infected with various dilutions of the infection/transfection viral stocks, overlaid with nutrient agarose media (equal volumes of agarose and 2X M199) and incubated 6-7 days for plaque development to occur. The agarose overlay and plate were marked with the same three asymmetrical dots (India ink) to aid in positioning the Nitrocellulose (NC) membrane (cell monolayer) and agarose overlay. The agarose overlay was transferred to the lid of the 10 cm 1, WO 96/40880 PCT/US96/11187 dish and stored at 4*C. The CEF monolayer was overlaid with a pre-wetted (PBS) NC membrane and pressure applied to transfer the monolayer to the NC membrane. Cells contained on the NC membrane were then lysed by placing the membranes in 1.5 ml of 1.5 M NaCI and 0.5 M NaOH for five minutes. The membranes were placed in 1.5 ml of 3 M sodium acetate (pH 5.2) for five minutes. DNA from the lysed cells was bound to the NC membrane by baking at 0 C for one hour. After this period the membranes were prehybridized with a solution containing 6X SSC, 3% skim milk, 0.5% SDS, salmon sperm DNA (50 gg/ml) and incubated at 65°C for one hour. Radio-labeled probe DNA (alpha 32
P-
dCTP) was added and incubated at 65 0 C overnight (12 hours). After hybridization the NC membranes were washed two times (30 minutes each) with 2X SSC at 65 0 C, followed by two additional washes at 65 0 C with 0.5X SSC. The NC membranes were dried and exposed to X-ray film (Kodak X- OMAT, AR) at -70 0 C for 12 hours. Plaques corresponding to positive signals seen on the autoradiogram were picked from the agarose overlay, using a pasteur pipette, and were resuspended into 1 ml of CEF media and stored at 0 C. Typically, 5-6 rounds of plaque purification were required to ensure purity of the recombinant virus.
SCREEN FOR FOREIGN GENE EXPRESSION IN RECOMBINANT FPV USING BLACK PLAQUE ASSAYS. To analyze expression of foreign antigens expressed by recombinant fowlpox viruses, monolayers of CEF cells were infected with recombinant FPV, overlaid with nutrient agarose media and incubated for 6-7 days at 37 0 C for plaque development to occur. The agarose overlay was removed from the dish, the cells fixed with 100% methanol for 10 minutes at room temperature and air dried. The primary antibody was diluted to an appropriate concentration with PBS and incubated on the cell monolayer for two hours at room temperature. Unbound antibody was removed from the cells by washing three times with PBS at room temperature. A WO 96/40880 PCT/US96/11187 -31horseradish peroxidase conjugated secondary antibody was diluted with PBS and incubated on the cell monolayer for two hours at room temperature. Unbound secondary antibody was then removed by washing the cells three times with PBS at room temperature. The cells were incubated 15-30 minutes at room temperature with freshly prepared substrate solution (100 Ag/ml 4-chloro-1naphthol, 0.003% H 2 0 2 in PBS). Plaques expressing the correct antigen stain black.
SCREEN FOR RECOMBINANT FPV EXPRESSING ENZYMATIC MARKER GENES. When the E. coli 0-galactosidase (lacZ) or 3glucuronidase (uidA) marker gene was incorporated into a recombinant virus the plaques containing recombinants were visualized by a simple assay. The enzymatic substrate was incorporated (300 gg/ml) into the agarose overlay during the plaque assay. For the lacZ marker gene the substrates Bluogal M (halogenated indolyl-o-Dgalactosidase, Bethesda Research Labs) for blue plaques or CPRG (chlorophenol Red Galactopyranoside, Boehringer mannheim) for red plaques were used. For the uidA marker gene the substrate X-Glucuro Chx (5-bromo-4chloro-3-indolyl-o-D-glucuronic acid Cyclohexylammonium salt, Biosynth AG) was used. Plaques that expressed active marker enzyme turned either red or blue. The plaques were then picked onto fresh cells and purified by further plaque isolation.
RNA ISOLATED FROM CONCANAVALIN A STIMULATED CHICKEN SPLEEN CELLS. Chicken spleens were dissected from 3 week old SPAFAS hatched chicks, washed, and disrupted through a syringe/needle to release cells. After allowing stroma and debri to settle out, the cells were pelleted and washed twice with PBS. The cell pellet was treated with a hypotonic lysis buffer to lyse red blood cells, and splenocytes were recovered and washed twice with PBS.
Splenocytes were resuspended at 5 x 106 cells/ml in RPMI p WO 96/40880 PCT/US96/11187 -32containing 5% FBS and 5 Ag/ml Concanavalin A and incubated at 390 for 48 hours. Total RNA was isolated from the cells using guanidine isothionate lysis reagents and protocols from the Promega RNA isolation kit (Promega Corporation, Madison WI). 4pg of total RNA was used in each 1st strand reaction containing the appropriate antisense primers and AMV reverse transcriptase (Promega Corporation, Madison WI). cDNA synthesis was performed in the same tube following the reverse transcriptase reaction, using the appropriate sense primers and Vent® DNA polymerase (Life Technologies, Inc. Bethesda, MD).
HOMOLOGY VECTOR 451-79.95. The plasmid 451-79.95 was constructed for the purpose of inserting the NDV HN gene into FPV. A lacZ marker gene followed by the NDV HN gene was inserted as a cassette into the homology vector 443- 88.14 at the unique Sfil site.

Several of these restriction fragments were subjected to restriction mapping analysis. Unique blunt cutting restriction endonuclease sites were identified and mapped within the cloned FPV DNA regions. The blunt restriction sites were converted to Not I and Sfi I sites through the use of synthetic DNA linkers (oligo 66.04; GGCGGCCGCGGCCCTCGAGGCCA-3' SEQ ID NO: 1 and oligo 66.05; 5' TGGCCTCGAGGGCCGCGGCCGCC 3' SEQ ID NO: A 0galactosidase (lacZ) marker gene was inserted in each of the potential sites. A plasmid containing such a foreign DNA insert may be used according to the HOMOLOGOUS RECOMBINATION PROCEDURE FOR GENERATING RECOMBINANT FPV to construct a FPV containing the foreign DNA. For this procedure to be successful it is important that the insertion site be in a region non-essential to the replication of the FPV and that the site be flanked with FPV DNA appropriate for mediating homologous recombination between virus and plasmid DNAs. The plasmids containing the lacZ marker gene were utilized in the HOMOLOGOUS RECOMBINATION PROCEDURE FOR GENERATING RECOMBINANT FPV. The generation of recombinant virus was determined by the SCREEN FOR RECOMBINANT FPV EXPRESSING ENZYMATIC MARKER GENES. Three sites were successfully used to generate a recombinant viruses. In each case the resulting virus was easily purified to 100%, clearly defining an appropriate site for the insertion of foreign DNA.

TESTING OF RECOMBINANT FPV EXPRESSING NDV ANTIGENS Groups of one day old SPF chicks (HyVac Inc.) were immunized with recombinant fowlpox viruses S-FPV-035, S- FPV-041, or S-FPV-043. Non vaccinated controls were also included. Three weeks post-vaccination, the birds were challenged intramuscularly with either virulent NDV or virulent FPV (Table The challenged chicks were observed daily for 14 days for clinical signs and death due to NDV. Non vaccinated control birds showed 100% mortality. S-FPV-043 vaccinated birds showed 100% protection against FPV challenge. Birds vaccinated with S-FPV-035 showed 95% protection compared with 85% seen 1 WO 96/40880 PCT/US96/11187 -52with birds immunized with S-FPV-041. These results suggest that recombinants expressing HN or F alone provide only partial protection. When both NDV proteins are combined into the same virus S-FPV-043, an enhancement of protection against lethal NDV challenge is obtained, resulting in a lower protective dose. The chicks that were challenged with FPV were scored for pox lesions. Non vaccinated control birds showed no protection against FPV lesions. Birds vaccinated with S-FPV-043 were completely protected from FPV lesions.
The duration of immunity conferred by vaccination with S- FPV-043 was examined. A group of SPF chicks was immunized with S-FPV-043 at one day of age and then challenged six weeks post-vaccination with either NDV or FPV. Complete protection was observed against both NDV and FPV challenge in S-FPV-043 vaccinated birds, whereas non vaccinated controls were totally susceptible to both challenge viruses. These results suggest that the duration of immunity afforded by vaccination with S-FPV- 043 would span the life of a broiler bird 6 weeks).
The effect of vaccinating hens in lay with the recombinant S-FPV-043 was evaluated by assessing egg production post-vaccination. One group of 50 hens was vaccinated and a second group of 50 hens, housed under conditions identical to the vaccinated group, served as non vaccinated controls. Daily egg production was monitored for four weeks post-vaccination. No differences were observed in egg production between the two groups of hens, indicating this vaccine will not adversely affect egg production in laying hens.
A study was conducted to determine whether S-FPV-043 could actively immunize chicks in the presence of maternal antibodies to both NDV and FPV. Chicks obtained from NDV and FPV immunized flocks were vaccinated with S- WO 96/40880 PCT/US96/11187 -53- FPV-043 and three weeks after vaccination, they were challenged with either virulent NDV or virulent FPV.
Clinical responses were compared with non vaccinated chicks from the same flock and with non-vaccinated chicks from an antibody negative flock (Table Chicks derived from antibody negative flocks showed 100% mortality after NDV challenge. Protection against NDV challenge, in nonvaccinated chicks known to have maternally derived antibody against NDV, ranged from 30 to 60%. Protection levels increased, to a range of 75 to 85%, when the maternal antibody positive chicks were vaccinated with S- FPV-043 suggesting an active immunization. The increase in NDV protection from 30% to 75% (flock 1) and 55% to (flock 2) clearly demonstrate the ability of S-FPV- 043 to partially overcome maternal antibody to both NDV and FPV. A decrease in FPV protection was observed in flock 1, suggesting some inhibition of FPV replication.

This virus is useful as a multi-valent vaccine against Newcastle Diseases, Infectious Bronchitis, and Fowlpox.
Example 6 Recombinant fowlpox virus, S-FPV-099 or S-FPV-101, expressing chicken interferon (cIFN) or S-FPV-100, expressing chicken myelomonocytic growth factor (cMGF), are useful to enhance the immune response when added to vaccines against diseases of poultry. Chicken myelomonocytic growth factor (cMGF) is homologous to mammalian interleukin-6 protein, and chicken interferon (cIFN) is homologous to mammalian interferon Type I. When used alone or in combination with vaccines against specific avian diseases, S-FPV-099, S-FPV-100 and S-FPV- 101 provide enhanced mucosal, humoral, or cell mediated immunity against avian disease-causing viruses including, but not limited to, Marek's disease virus, Newcastle disease virus, infectious laryngotracheitis virus, infectious bronchitis virus, infectious bursal disease virus.

Supernatants from S-FPV-099 have interferon activity in cell culture. Addition of S-FPV-099 conditioned media to chicken embryo fibroblast (CEF) cell culture inhibits infection of the CEF cells by vesicular stomatitis virus or by herpesvirus of turkeys.

S-FPV-100 S-FPV-100 is a recombinant fowlpox virus that expresses two foreign genes. The genes for chicken myelomonocytic growth factor (cMGF) and E. coli lacZ were inserted at WO 96/40880 PCT/US96/11187 -71the uniqe SnaBI restriction endonuclease site in the 2.8 kB EcoRI FPV genomic fragment (681 insertion site).

S-FPV-100 is useful to enhance the immune response alone or when added to vaccines against diseases of poultry.
S-FPV-101 S-FPV-101 is a recombinant fowlpox virus that expresses four foreign genes. The genes for chicken interferon (cIFN) and E. coli lacZ were inserted at the uniqe SnaBI restriction endonuclease site in the 2.8 kB EcoRI FPV genomic fragment (681 insertion site). The cIFN gene is under the control of a synthetic late/early promoter LP2EP2, and the E. coli lacZ gene is under the control of a synthetic late promoter LP1. The genes for Newcastle Disease virus F protein and HN protein were inserted at the 680 insertion site. The F and HN genes are each under 4 WO 96/40880 PCT/US96/11187 -72the control of a synthetic early/late promoter EP1LP2.
S-FPV-101 was derived from S-FPV-043. This was accomplished utilizing the homology vector 751-07.D1 (see Materials and Methods) and virus S-FPV-043 in the HOMOLOGOUS RECOMBINATION PROCEDURE FOR GENERATING RECOMBINANT FPV.

Example 7 Recombinant fowlpox virus expressing Newcastle's disease virus HN and F proteins lacking the membrane anchor sequences is a superior vaccine against fowlpox and Newcastle's disease.
Day old chicks from hens which have been exposed to or vaccinated against Newcastle's disease virus carry WO 96/40880 PCT/US96/11187 -73antibodies to NDV which may neutralize a vaccine containing a recombinant fowlpox virus expressing the NDV HN and F proteins. In vitro virus neutralization
(VN)
assays using VN monoclonal antibodies specific for either NDV HN or F proteins have been shown to neutralize recombinant fowlpox virus expressing the NDV HN and F proteins. These results suggest that the NDV HN and F glycoproteins are incorporated into the fowlpox virus virion. To increase the efficacy of a vaccine in the presence on maternal antibodies against Newcastle's disease virus, a recombinant fowlpox virus is constructed which expresses the NDV HN and F proteins lacking the membrane anchor domains of each protein. The resulting recombinant virus produces NDV HN and F proteins secreted into the serum of the vaccinated animal producing a strong humoral and cell mediated immune response to the Newcastle's disease virus. The NDV HN and F proteins are not presented on the surface of the FPV particle and thus evade neutralization by maternal antibodies present in the vaccinated day old chicks.
The hemagglutinin-Neuraminidase (HN) and Fusion genes from the B1 strain of Newcastle Disease Virus (ATCC VR- 108) were isolated as cDNA clones, using oligo dT primed poly A selected mRNA.
The fusion protein mediates penetration of NDV into host cells by fusion of the viral envelope with the host cell plasma membrane. A posttranslational cleavage of inactive precursors Fo into two disulfide-bonded polypeptides, Fl and F2, is necessary to produce fusion active F protein and thereby yield infectious virions.
The new hydrophobic N-terminus of Fl generated after cleavage of Fo is responsible for the fusion characteristic of paramyxoviruses and thus determines virulence. The required proteolytic cleavage signal (paired basic residues) in the NDV Bl strain is altered, WO 96/40880 PCT/US96/11187 -74thereby preventing cleavage of Fo into Fl and F2, resulting in an attenuated NDV strain.
The addition of the NDV F signal sequence (aal-25) to VP2 (vFP147), resulted in the secretion of VP2 in the TC fluid, but abolished its protective response (Paoletti, et. al WO 93/03145). Three hydrophobic domains exist within the F glycoprotein which interact with the lipid bilayer The signal sequence at the N-terminus of the primary translation product Fo; the N-terminus of Fl; and the transmembrane anchor domain near the Cterminus of Fl. The F glycoprotein of the Bi strain of NDV is 544 amino acids in length with the transmembrane anchor domain spanning 27 amino acids from position 500 to 526 (LITYIVLTIISLVFGILSLILACYLMY). Amino acids 1-499 of the NDV F protein are expressed under the control of a synthetic promoter element which functions as both an early and late promoter, such as EP1LP2 or LP2EP2, directing expression throughout the reproduction cycle.
This results in the deletion of amino acids 527-544, the cytoplasmic tail, thought to interact with the inner membrane protein before or during virus assembly. A recombinant fowlpox virus is constructed which expresses the NDV F protein lacking the C-terminal membrane anchor domain from a synthetic early/late promoter.
The hemagglutinin-neuraminidase (HN) glycoprotein provides NDV with the ability to agglutinate and elute erythrocytes. The process consists of two stages: attachment of the virus to the receptor on the red blood cell surface (agglutination) and destruction of the receptor by the neuraminidase enzyme activity (elution).
The major hydrophobic anchor domain is present near the N-terminus of HN, supporting the view that the N-terminus is anchored to the lipid bilayer. The HN glycoprotein of the B1 strain of NDV is 577 amino acids in length with the transmembrane anchor domain spanning 28 amino acids 1, WO 96/40880 PCT/US96/11187 from position 27 to 54 (IAILFLTVVTLAISVASLLYSMGASTPS).
The extreme N-terminal amino acids (1 to 26) are relatively hydrophilic. Amino acids 55 to 577 of the HN protein are expressed under the control of a synthetic promoter element which functions as both an early and late promoter, such as EP1LP2 or LP2EP2, directing expression throughout the reproduction cycle. THE NDV HN polypeptide has a membrane transport signal sequence, such as the PRV gX signal sequence, at its amino terminus to direct the protein to be secreted into the serum of a vaccinated animal. A recombinant fowlpox virus is constructed which expresses the NDV HN protein lacking the N-terminal membrane anchor domain and containing an N-terminal PRV gX signal sequence from a synthetic early/late promoter. Alternatively the NDV HN polypeptide contains a deletion of the transmembrane anchor domain spanning 28 amino acids from position 27 to 54 and retains amino acids 1 to 26 and 55 to 577. A recombinant fowlpox virus is constructed which expresses the NDV HN protein lacking the membrane anchor domain (amino acids 27 to 54) from a synthetic early/late promoter.
A recombinant fowlpox virus is constructed which expresses both the NDV HN and F proteins lacking the membrane anchor domains of each protein from a synthetic early/late promoter. The resulting recombinant virus produces NDV HN and F proteins secreted into the serum of the vaccinated animal producing a strong humoral and cell mediated immune response to the Newcastle's disease virus. The NDV HN and F proteins are not presented on the surface of the FPV particle and thus evade neutralization by maternal antibodies present in the vaccinated day old chicks.
Example 8 Recombinant fowlpox virus expressing cell surface WO 96/40880 PCT/US96/11187 -76receptors on the surface of the FPV viral particle useful for targeting gene products to specific tissues or organs.
Serum from chickens carrying maternal antibodies to Newcastle's disease virus inhibits productive infection and plaque formation by S-FPV-043 on chicken embryo fibroblasts in cell culture. One explanation for this result is that the antigenic epitopes of the NDV HN and F proteins expressed in S-FPV-043 are displayed on the surface of the fowlpox viral particle. Display of proteins on the surface of the FPV particle is useful to target specific gene products to specific normal cell types or tumor cell types. Proteins which are displayed on the surface of the FPV particle include but are not limited to integrins which would target the virus to integrin receptors on the cell surface; erythropoetin which would target the virus to erythropoetin receptors on the surface of red blood cells; antibodies or other proteins which would target to specific proteins or receptors on the surface of normal or tumor cells. The fowlpox virus also delivers cytokines, interleukins, interferons, or colony stimulating factors which stimulate a strong humoral or cell mediated immune response against a tumor or disease causing organism. The proteins displayed on the surface of the fowlpox virus are expressed from the fowlpox genome as fusion proteins to the membrane anchor domains of the NDV HN or F proteins, or to other proteins containing membrane anchor domains. The cytokines, interleukins, interferons, or colony stimulating factors are expressed as fusion proteins to PRV gX, E. coli P-galactosidase or another protein in a soluble, not membrane bound, form. The fusion protein stabilizes the cytokine protein and allows it to diffuse in the serum of the animal to reach its cellular target.
WO 96/40880 PCT/US96/11187 -77- Example 9 S-FPV-098 S-FPV-098 is a recombinant fowlpox virus that expresses two foreign genes. The genes for infectious bursal disease virus (IBDV) polymerase gene and E. coli lacZ were inserted at the 681 insertion site. The IBDV polymerase gene is under the control of a synthetic late/early promoter LP2EP2, and the E. coli lacZ gene is under the control of a synthetic late promoter LP1.
S-FPV-098 was derived from S-FPV-001. This was accomplished utilizing the homology vector 749-75.82 (see Materials and Methods) and virus S-FPV-001 in the HOMOLOGOUS RECOMBINATION PROCEDURE FOR GENERATING RECOMBINANT FPV. The transfection stock was screened by the SCREEN FOR RECOMBINANT FPV EXPRESSING ENZYMATIC MARKER GENES. The final result of red plaque purification was the recombinant virus designated S-FPV-098. This virus was assayed for -galactosidase expression, purity, and insert stability by multiple passages monitored by the blue plaque assay as described in Materials and Methods. After the initial three rounds of purification, all plaques observed were blue indicating that the virus S-FPV-098 was pure, stable, and expressing the foreign gene.
S-FPV-098 is useful for expression of IBDV polymerase protein. S-FPV-098 is useful in an in vitro approach to a recombinant IBDV attenuated vaccine. RNA strands from the attenuated IBDV strain are synthesized in a bacterial expression system using T3 or T7 promoters (pBlueScript plasmid; Stratagene, Inc.) to synthesize double stranded short and long segments of the IBDV genome. The IBDV double stranded RNA segments and S-FPV-098 are transfected into Vero cells. The fowlpox virus expresses the IBDV polymerase but does not replicate in Vero cells.
11 "WO 96/40880 PCTIUS96/11187 -78- The IBDV polymerase produced from S-FPV-098 synthesizes infectious attenuated IBDV virus from the double stranded RNA genomic templates. The resulting attenuated IBDV virus is useful as a vaccine against infectious bursal disease in chickens.
As an alternative to the construction of a IBD vaccine using a viral vectored delivery system and/or subunit approaches, IBD virus RNA is directly manipulated reconstructing the virus using full length RNA derived from cDNA clones representing both the large (segment A) and small (segment B) double-stranded RNA subunits.
Generation of IBD virus is this manner offers several advantages over the first two approaches. First, if IBD virus is re-generated using RNA templates, one is able to manipulate the cloned cDNA copies of the viral genome prior to transcription (generation of RNA). Using this approach, it is possible to either attenuate a virulent IBD strain or replace the VP2 variable region of the attenuated vaccine backbone with that of virulent strains. In doing so, the present invention provides protection against the virulent IBDV strain while providing the safety and efficacy of the vaccine strain.
Furthermore, using this approach, the present invention constructs and tests temperature sensitive IBD viruses generated using the RNA polymerase derived from the related birnavirus infectious pancreatic necrosis virus (IPNV) and the polyprotein derived from IBDV. The IPNV polymerase has optimum activity at a temperature lower than that of IBDV. If the IPNV polymerase recognizes the regulatory signals present on IBDV, the hybrid virus is expected to be attenuated at the elevated temperature present in chickens. Alternatively, it is possible to construct and test IBD viruses generated using the RNA polymerase derived from IBDV serotype 2 viruse and the polyprotein derived from IBDVserotype 1 virus.
"WO 96/40880 PCTIUS96/11187 -79cDNA clones representing the complete genome of IBDV (double stranded RNA segments A and B) is constructed, initially using the BursaVac vaccine strain (Sterwin Labs). Once cDNA clones representing full length copies of segment A and B are constructed, template RNA is prepared. Since IBDV exists as a bisegmented doublestranded RNA virus, both the sense and anti-sense RNA strands of each segment are produced using the pBlueScript plasmid; Stratagene, Inc.). These vectors utilize the highly specific phage promoters SP6 or T7 to produce substrate amounts of RNA in vitro. A unique restriction endonuclease site is engineered into the 3' PCR primer to linearize the DNA for the generation of run-off transcripts during transcription.
The purified RNA transcripts (4 strands) are transfected into Vero cells to determine whether the RNA is infectious. If IBD virus is generated, as determined by black plaque assays using IBDV specific Mabs, no further manipulations are required and engineering of the vaccine strain can commence. The advantage of this method is that engineered IBD viruses generated in this manner will be pure and require little/no purification, greatly decreasing the time required to generate new vaccines.
If negative results are obtained using the purified RNA's, functional viral RNA polymerase is required by use of a helper virus. Birnaviruses replicate their nucleic acid by a strand displacement (semi-conservative) mechanism, with the RNA polymerase binding to the ends of the double-stranded RNA molecules forming circularized ring structures (Muller Nitschke, Virology 159, 174- 177, 1987). RNA polymerase open reading frame of about 878 amino acids in fowlpox virus is expressed and this recombinant virus (S-FPV-098) is used to provide functional IBDV RNA polymerase in trans. Fowlpox virus expressed immunologically recognizable foreign antigens in non-avian cells (Vero cells), where there are no signs WO 96/40880 PCT/US96/11187 of productive replication of the viral vector (Paoletti et al., Technological Advances in Vaccine Development, 321-334, 1988, Alan R. Liss, In the present invention the IBDV polymerase protein is expressed in the same cells as the transfected RNA using the fowlpox virus vector without contaminating the cells with FPV replication.
With the demonstration that IBD virus is generated in vitro using genomic RNA, an improved live attenuated virus vaccines against infectious bursal disease is developed. Using recombinant DNA technology along with the newly defined system of generating IBD virus, specific deletions within the viral genome, facilitating the construction of attenuated viruses are made. Using this technology, the region of IBDV responsible for virulence and generate attenuated, immunogenic IBDV vaccines are identified. The present invention provides a virulent IBD strain or replacement of the VP2 variable region of the attenuated vaccine backbone with that of a virulent strain, thus protecting against the virulent strain while providing the safety and efficacy of the vaccine strain.
Example The chicken interferon (cIFN) gene was cloned into wild type (FPV) viruses by homologous recombinant techniques.
Briefly, the entire coding region of cIFN was isolated from activated chicken spleen cell RNA by RT/PCR using primer sequences from the recently published cIFN sequence (Sekellick, et al., 1994). Recombinant FPV viruses containing cIFN, and FPV/cIFN (S-FPV-099), were engineered to contain the entire cIFN ORF under the control of a synthetic pox virus promoter (LP2EP2), which functions as both an early and late promoter, directing expression throughout the entire viral replication cycle.
WO 96/40880 PCT/US96/11187 -81- A third recombinant virus, FPV/cIFN+NDV, (S-FPV-101) was made in a similar manner, except that a FPV virus previously engineered to contain the Newcastle Disease (NDV) antigens HN and F was used as the parent virus during homologous recombination, thus yielding a recombinant fowlpox virus co-expressing the cIFN and NDV genes. All recombinant viruses contain the lac Z gene engineered in tandem with cIFN under the control of a synthetic late (LP1) pox promoter. All promoter/gene constructs were sequenced at the promoter/cIFN junction to confirm the integrity of the proper DNA coding frame.
Co-expression of 0-galactosidase facilitated the isolation and plaque purification of the recombinant viruses. Independent viral insertion sites were used for insertion of the cIFN gene and the NDV genes in the fowlpox virus. The insertion sites were found to interrupt nonessential virus genes in both SPV and FPV.
To confirm the presence of the cIFN gene, recombinant viral DNAs were analyzed by PCR, using cIFN specific primers flanking the coding region. All viral DNA's yielded the expected 600 bp amplified cIFN DNA product.
In addition, southern blot analysis on the viral DNA was performed using a non-radioactive labeled cIFN cDNA probe. Plasmid constructs containing the cIFN gene cassettes were sequenced across the transcriptional and translational initiation/termination signals, to confirm the integrity of the ORF.
Growth Properties of Recombinant Viruses in Cell Culture.
Recombinant FPV/cIFN and FPV/cIFN+NDV were found to be attenuated with respect to their growth in chicken embryo fibroblast (CEF) cells. Plaque size was decreased significantly and viral titers were 0.9-1.4 logs less when compared to wild type FPV. We suggest that fowlpox virus has anti-IFN mechanisms, similar to anti-IFN 1. WO 96/40880 PCT/US96/11187 -82mechanisms reported for other pox viruses, e.g. vaccinia, cowpox. And that these mechanisms help the virus to overcome the inhibitory effects of exogenously expressed cIFN. Therefore, fowlpox virus is able to infect, replicate and retain a productive infectious state.
In Vivo Properties of Recombinant FPV/cTFN Virus in Chicks.
10-day old chicks were inoculated, subcutaneously, with recombinant FPV/cIFN (S-FPV-099) virus at increasing dosages. At 10 days post inoculation, all chicks were inoculated with a mixture of sheep red blood cells (SRBC) and Brucella abortus At 15 days post FPV/cIFN virus inoculation, sera was collected, total body weights and antibody responses to SRBC's and BA were measured, and chicks were sacrificed for necropsy analysis. These data show that there were no significant differences in chick body weight, SRBC and BA antibody responses or gross pathologyc associated with inoculation of recombinant FPV/cIFN virus, as compared to chicks inoculated with PBS alone. Therefore, this virus appears to be safe in 10-day old chicks.

Chick mortality was recorded 2 weeks post vaccination. Chicks vaccinated with NDV B1l alone or with NDV B1l plus FPV wild-type virus showed mortality compared to chickens co-vaccinated with NDV-Bl and FPV/cIFN, in which group, all chicks remained alive. Subsequently, all chicks were challenged at 4 weeks post vaccination with a pathogenic strain of NDV (GB-TX). All chicks were protected, except for those in the "no treatment control group. These data show that NDV Bl vaccine induced mortality was reduced without affecting the vaccine's protective ability.
