Abstract: This study examined the occurrence of drug resistance and virulence-associated genes in 25 isolates of avian pathogenic Escherichia coli (APEC). A total of five genes linked to antimicrobial resistance strA, strB, tetA, tetB, and blaTEM were selected based on the phenotypic resistance observed to the corresponding antibiotics. A relatively high prevalence rate (92%) was found for the blaTEM gene. Moderate occurrence rates were recorded for strB (64%), tetB (56%), tetA (44%), and strA (40%).
