Species identification was confirmed by MALDI-TOF MS for 82 isolates. Common resistance mechanisms were determined by WGS of pooled E. coli isolates. PFGE combined with specific probes determined the presence of common resistance mechanisms in all isolates. Phylotypes, multilocus STs, core-genome multilocus STs, resistance genes and virulence genes were determined by in silico analysis of 38 genomes.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results and conclusions<\/jats:title>\n                  <jats:p>Analysis of isolates collected without selection (n\u202f=\u202f33) indicated that cefotaxime resistance in E. coli was 42% (14\/33) and estimated meropenem resistance at 9%. The remaining 58% (19\/33) were additionally susceptible to ampicillin, trimethoprim, ciprofloxacin and aminoglycosides. The most common ST among the cefotaxime-resistant E. coli was ST167 (29%), followed by ST410 (17%) and ST648 (10%). E. coli ST131 was absent from the collection. Sixty-three isolates were resistant to cefotaxime and harboured blaCTX-M-15 [54% (34\/63)] or blaCMY-42 [46% (29\/63)], of which 10% (6\/63) harboured both genes. Carbapenem resistance was due to blaNDM-5, found in 10\/63 cefotaxime-resistant isolates, and\/or blaOXA-181, found in 4\/63 isolates. NDM-5 was encoded by IncX3 and\/or IncFII plasmids and CMY-42 was mostly encoded by IncI plasmids. NDM-5 appears to have replaced NDM-1 in this region and CMY-42 appears to be in the process of replacing CTX-M-15.<\/jats:p>\n
