Clonal CTX-M-15-Producing Escherichia coli ST-949 Are Present in German Surface Water.

ABSTRACT: Extended-spectrum beta-lactamase (ESBL)-producing bacterial isolates are emerging within the last years. To understand this emergence, a thorough genome-based analysis of ESBL isolates from different sources (One Health approach) is needed. Among these, analysis of surface water is underrepresented. Therefore, we performed a genome-based analysis of ESBL-producing Escherichia coli isolates from surface water samples. Water samples were collected from eleven different surface water sites (lakes, river). ESBL-producing E. coli were recovered from these samples using filters and chromogenic media. Whole-genome sequencing of ESBL-producing E. coli was performed followed by determination of the multilocus sequence type (ST), ESBL-type, and virulence genes. Phylogenetic anal
