Résumé
Escherichia coli producing Extended-Spectrum-β-Lactamases (ESBL) are a major public health hazard worldwide. The most frequent ESBL belong to the CTX-M family. This study follows their prevalence in pathogenic and non-pathogenic ESBL-producing E. coli isolated from young diarrheic and septicaemic calves over three calving seasons. The triplex PCR targeted three main groups: CTX-M-1, CTX-M-2 and CTX-M-9. Of the 394 isolates studied, 388 (98.5%) were positive, with a majority of CTX-M-1 (243, 61.7%), following by CTX-M-9 (74, 18.8%) and CTX-M-2 (64, 16.2%). The progressive decrease of ESBL-resistance of pathogenic E. coli is not linked to any shift in genetic background, bla
