Summary: | Six
Escherichia coli O25b ST131 isolates, which were mostly hospital-acquired but from various types of samples, were found to carry
bla
CTX-M-3a,
bla
CTX-M-14, or
bla
CTX-M-65 genes, demonstrating that such isolates have emerged in China. The
bla
CTX-M genes were mostly carried by IncFII-related conjugative plasmids. All isolates were also resistant to ciprofloxacin and gentamicin and had substitutions in GyrA and carried an
aac(3)-II gene. |
