    Gram-Negative Bacteria: Antibiogram of Bacteria - Year 2020 (Icu at Kfafh)

    Uploaded by

    jen nalus
    This document summarizes the antibiograms of gram-negative and gram-positive bacteria isolated at the ICU of a hospital in 2020. For gram-negatives, E. coli was the most common, followed by Klebsiella pneumoniae and Pseudomonas aeruginosa. Amikacin and gentamicin were the most effective antibiotics. For gram-positives, Staphylococcus aureus was most common, with methicillin-sensitive strains more prevalent than methicillin-resistant strains. Linezolid and vancomycin were effective against all gram-positive bacteria.
