Abstract :

This study was conducted to determine the occurrence of antimicrobial resistance to the extended-spectrum cephalosporins (ESC) in Escherichia coli isolates. The isolates were collected from retail meat products collected in the Maritime Provinces of Canada. Our analyses involved the use of both selective and traditional culture methods; we also conducted genotype analyses using multiplex polymerase chain reactions. ESC-resistant (ESC-R) E. coli were detected in 33 of 559 samples (5.9%) using the traditional culture method, compared with 151 of 557 samples (27.1%) using the selective culture method. We recovered more isolates of ESC-R E. coli from poultry compared with beef and pork (P Key words: antimicrobial resistance, extended-spectrum cephalosporins, [beta]-lactamases, Escherichia coli, retail meat products.

Escherichia coli CSE-R a ete detecte dans 33/559 (5,9 %) des echantillons par la methode de culture traditionnelle, contre 151/557 (27,1 %) par la methode de culture selective. La recuperation des isolats d'E. coli CSE-R etait plus frequente chez la volaille que chez le boeuf et le porc (P Mots-cles : resistance aux antimicrobiens, cephalosporines a spectre etendu, [beta]-lactamases, Escherichia coli, produits de viande au detail.
