ABSTRACT
Antimicrobial resistance surveillance targeting agricultural animals is practiced in many countries but does not often include media selective for cephalosporin resistance. Here, we compared the frequency of recovery of resistant Escherichia coli using selective and non-selective media from the cecal contents of 116 chickens collected by the Canadian Integrated Program for Antimicrobial Resistance Surveillance (CIPARS). Third generation cephalosporin resistance was detected in 24 samples including 12, 10, and 2 on selective, non-selective, and both media, respectively. Isolates producing the CTX-M-1 ESBL were grown from 11 samples, 10 on selective medium only. Our results suggest that current surveillance approaches underestimate the true prevalence of resistance to critically important antimicrobials.
Évaluation de milieux sélectifs dans des programmes de surveillance antimicrobienne isolant Escherichia coli produisant des ß-lactamases à large spectre provenant de poulets à l'abattage. La surveillance de la résistance aux antimicrobiens ciblant les animaux d'élevage est pratiquée dans de nombreux pays mais n'inclut pas souvent les milieux sélectifs pour la résistance aux céphalosporines. Ici, nous avons comparé la fréquence d'isolement d'Escherichia coli résistants à l'aide de milieux sélectifs et non sélectifs à partir du contenu caecal de 116 poulets collectés dans le cadre du Programme intégré canadien de surveillance de la résistance aux antimicrobiens (PICRA). Une résistance aux céphalosporines de troisième génération a été détectée dans 24 échantillons dont 12, 10 et 2 sur des milieux sélectifs, non sélectifs et les deux, respectivement. Les isolats produisant les BLSE CTX-M-1 ont été cultivés à partir de 11 échantillons, 10 sur un milieu sélectif uniquement. Nos résultats suggèrent que les approches de surveillance actuelles sous-estiment la prévalence réelle de la résistance aux antimicrobiens d'importance critique.(Traduit par Dr Serge Messier).
