Abstract

The study aimed to determine the prevalence of Escherichia coli resistance to commonly used antimicrobials in poultry from Cajamarca, Peru. Cloacal swabs were taken from n = 105 clinically healthy poultry and cultured on MacConkey agar for isolation of E. coli. Antibiogram susceptibility testing was performed using the Disk Diffusion technique, and interpretation of resistance or susceptibility was based on the inhibition zones established by the Clinical and Laboratory Standards Institute. The prevalence of resistance to gentamicin (100%), neomycin (100%) and tylosin (96.19%) was "extra high", to tetracycline (59.05%) was "very high", to sulfamethoxazole/trimethoprim (43.81%) was "high" and to enrofloxacin (11.43%) was "moderate". In addition, multidrug resistance was observed with two (1.90%), three (27.62%), four (31.19%), five (26.67) and six (7.62%) combined antibiotics. Only cohabitation with other animal species represented a risk factor OR 2.357 [95%CI 1.049-5.297], p=0.038. A marked prevalence of bacterial resistance in E. coli from poultry in Cajamarca to commonly used antibacterials was highlighted. The need to implement effective control and prevention measures for antimicrobial resistance in poultry farming is emphasized to safeguard public health and food safety in the city.
