在4株假单胞菌的染色体上发现了金属β-内酰胺酶基因bla(Vim)。从养鸡场分离到一株铜绿假单胞菌，包括一株来自燕子(Yanornis Martini)的铜绿假单胞菌，一株来自苍蝇的恶臭假单胞菌，以及两株来自鸡的恶臭假单胞菌。这四个分离株共享两个变种的bla(Vim)携带的基因组环境，类似于临床上产生金属β-内酰胺酶的假单胞菌的相应区域。我们的研究表明，迫切需要对牲畜及其周围环境中的碳青霉烯酶产生菌进行监测。
Metallo-beta-lactamase gene bla(VIM) was identified on the chromosome of four Pseudomonas sp. isolates from a chicken farm, including one Pseudomonas aeruginosa isolate from a swallow (Yanornis martini), one Pseudomonas putida isolate from a fly, and two P. putida isolates from chickens. The four isolates shared two variants of bla(VIM)-carrying genomic contexts that resemble the corresponding regions of clinical metallo-beta-lactamase-producing Pseudomonas spp. Our study suggests that the surveillance of carbapenemase-producing bacteria in livestock and their surrounding environment is urgently needed.
