Occurrence of _bla_KPC-2, _bla_CTX-M, and mcr-1 in Enterobacteriaceae from Well Water in Rural China

Pan Sun et al. Antimicrob Agents Chemother. 2017.

Abstract

We report on the coexistence of mcr-1 and _bla_CTX-M in multidrug-resistant, extended-spectrum β-lactamase-producing Escherichia coli belonging to the sequence type 10 complex isolated from well water in rural China. Raoultella ornithinolytica with _bla_KPC-2 was also detected in well water from the same area. This study shows that genes coding for resistance to last-resort antibiotics are present in wells in rural China, indicating a potential source of antibiotic resistance.

Keywords: ESBL; antibiotic resistance; mcr-1.
