Human-Associated Extended-Spectrum β-Lactamase in the Antarctic

Escherichia coli bacteria with extended-spectrum β-lactamase (ESBL) type CTX-M resistance were isolated from water samples collected close to research stations in Antarctica. The isolates had blaCTX-M-1 and blaCTX-M-15 genotypes and sequence types (ST) indicative of a human-associated origin. This i...

Description
Summary:Escherichia coli bacteria with extended-spectrum β-lactamase (ESBL) type CTX-M resistance were isolated from water samples collected close to research stations in Antarctica. The isolates had blaCTX-M-1 and blaCTX-M-15 genotypes and sequence types (ST) indicative of a human-associated origin. This is the first record of ESBL-producing enterobacteria from Antarctica.
