| Popis: | The aim of this study was to compare the antimicrobial resistance profiles of top five enterohemorrhagic Escherichia coli (EHEC) and enteropathogenic E. coli (EPEC) to E. coli isolated from the fecal flora of the same adult cattle. Previous prevalence studies had led to the isolation by immunomagnetic separation (IMS) of 39 EHEC and 80 EPEC. Seven EHEC were resistant (17.9%), and six were multidrug resistant (MDR) (15.4%). None of the top five EHEC was resistant to azithromycin. Nine EPEC O26:H11 (11.3%) were resistant. They were all resistant to tetracycline, and four were MDR (5.0%). An E. coli strain was isolated from the feces (without preselection by IMS) of 97 bovine carriers of top 5 strains. All these strains were susceptible to antibiotics. Comparative analyses did not reveal any differences between the cytotoxic activities of resistant EHEC and their susceptible counterparts or in the production of attachment and effacement lesions. These results highlighted the higher percentage of resistance of EHEC and EPEC strains compared to other E. coli. They also showed that resistance traits did not have any impact on the expression of virulence phenotypes in EHEC strains. |
