Nasal carriage of CTX-M-55-producing ST8369 in a healthy cohort in the city of Yangzhou, China.

This study aimed to investigate the prevalence and diversity of extended-spectrum β-lactamases (ESBL)-producing isolates from healthy individuals in a community and to elucidate their dissemination mechanism. Cefotaxime-resistant were isolated from 95 samples of healthy persons from one community in Yangzhou, China, and were tested for minimal inhibitory concentrations of 14 antimicrobial agents. The isolates were subjected to whole genome sequencing by Illumina Hiseq or PacBio single-molecule real-time sequencing.
