Resistance of Escherichia coli from the cloaca of buffy fish owls (Ketupa ketupu) to several antibiotics
Abstract
Antibiotic resistance has become a problem worldwide. Although E. coli is a normal flora, there are several pathogenic strains. This study aimed to determine the resistance patterns of E. coli isolates from cloacal swabs of buffy fish owls (Ketupa ketupu) from captive birds to streptomycin, tetracycline, gentamicin, nalidixic acid, ampicillin, and doxycycline using the Kirby-Bauer disc diffusion test. The inhibition zone formed was compared to the Clinical Laboratory Standards Institute (CLSI) 2020. The results showed that all isolates were resistant to ampicillin but were still sensitive to gentamicin. Two isolates remained sensitive to tetracycline, nalidixic acid, doxycycline, and streptomycin. One isolate was intermediate to streptomycin and was resistant to tetracycline, nalidixic acid, and doxycycline.
