Presence of VIM positive Pseudomonas species in chickens and their surrounding environment [PublishAheadOfPrint]

Metallo-β-lactamase gene bla_VIM was identified on the chromosome of four Pseudomonas spp. isolates from a chicken farm, including one P. aeruginosa from swallow (Yanornis martini), one P. putida from fly, and two P. putida from chickens. The four isolates shared two variants of bla_VIM-carrying genomic contexts, which resemble the corresponding regions of clinical MBL-producing Pseudomonas species. Our study suggests the surveillance of carbapenemase-producing bacteria in livestock and their surrounding environment is urgently needed.
