Emergence of in Enterobacteriaceae Isolates from Companion Animals in Guangzhou, China.

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 , that is, one , one , and four .

Clonal Spread of ST93 Carrying -Harboring IncN1-IncHI2/ST3 Plasmid Among Companion Animals, China.

The purpose of this study was to investigate the occurrence of plasmid-mediated colistin resistance gene in Enterobacteriaceae isolates from companion animals in Guangzhou, China. Enterobacteriaceae isolated from 180 samples collected from cats and dogs were screened for by PCR and sequencing. MCR-1-producing isolates were further characterized by multilocus sequence typing and pulsed-field gel electrophoresis (PFGE).
