Antimicrobial Susceptibility and Virulence of mcr-1-Positive Enterobacteriaceae in China, a Multicenter Longitudinal Epidemiological Study.

ABSTRACT: This study was to investigate the prevalence of mcr-1-positive Enterobacteriaceae (MPE) in intra-abdominal infections (IAIs), urinary tract infections (UTIs), and lower respiratory tract infections (LRTIs) in China. A total of 6,401 Enterobacteriaceae isolates were collected consecutively from IAI, UTI, and LRTI patients in 19 hospitals across mainland China during 2014-2016. MPE isolates were screened by PCR detection for the mcr gene. The resistance profiles were tested by antimicrobial susceptibility test. All MPE isolates were characterized by pulsed-field gel electrophoresis (PFGE), multi-locus-sequence typing, O and H serotyping, and whole-genome sequencing. Among the 6,401 Enterobacteriaceae isolates, 17 Escherichia coli strains (0.27%) were
