This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/our-business/policies/article-withdrawal). This article has been retracted at the request ofthe corresponding author and the editor-in-chief. The authors have notified the journal that Fig. 3E and 3F in this article was a duplicate image of Fig. 3C of the article published by Weidong Qian, Miao Liu, Yuting Fu, Ting Wang, Jianing Zhang, Min Yang, Zhaohuan Sun, Xiang Li, and Yongdong Li in Foodborne Pathogens and Disease 129 (2020) 528-534 https://www.liebertpub.com/doi/10.1089/fpd.2019.2751 and requested for retraction. The authors have subsequently admitted that Figs. 3A, 3D and 4B in this article were duplicated from Figs. 3A, 5A and 7B of the article published by Weidong Qian, Yuting Fu, Miao Liu, Ting Wang, Jianing Zhang, Min Yang, Zhaohuan Sun, Xiang Li and Yongdong Li in Antibiotics 8 (2019) 220 https://www.mdpi.com/2079-6382/8/4/220, which has been retracted https://www.mdpi.com/2079-6382/9/6/322. The authors have claimed that there were errors in the preparation of figures for three papers which had been submitted to multiple journals from August to October 2019. The authors have provided replacement images for Figs. 3 and 4 of this article, but these data did not resolve the concerns that call into question the reliability of the study findings. In light of these issues, the journal has decided to retract the article. The authors assert the findings, that ursolic acid exerted antibacterial activity against carbapenem-resistant Enterobacter cloacae, are nevertheless reliable.
