The study investigated carbapenemase-producing Enterobacteriaceae from companion animals in Guangzhou, China, and found 6 isolates positive for bla(NDM-5), including three E. coli isolates with identical characteristics. The presence of these bacteria among companion animals needs continuous surveillance.
The occurrence and characterization of carbapenemase-producing Enterobacteriaceae from companion animals in Guangzhou, China, are investigated. Six isolates (2.3%, 6/257) were positive for bla(NDM-5), that is, one Enterobacter cloacae, one Citrobacter freundii, and four Escherichia coli. Three E. coli isolates obtained from the same animal hospital were ST410 and showed identical pulse field gel electrophoresis pattern, resistance profiles, and resistance genes. bla(NDM-5) was located on IncX3 (n = 5) and IncK2 (n = 1) plasmid, respectively. The presence of carbapenemase-producing Enterobacteriaceae among companion animals needs continued surveillance.
