- Abstract
Globally, antimicrobial resistance in pathogenic bacteria has been increasingly reported from various origins presenting a serious threat for human and animal health. In Algeria, data on antimicrobial resistance in livestock are fragmented and scarce. Thus, this study we carried out in order to evaluate the antimicrobial susceptibility as well as the occurrence of extended spectrum beta-lactamase (ESBL) production in Escherichia coli isolates collected from several avian and bovine farms located in eastern Algeria. A total of 162 fecal samples from cattle and poultry were collected and investigated. Samples were streaked on MacConkey agar, and presumptive E. coli isolates were identified by API 20E system. Antimicrobial susceptibility was performed according to CLSI guideline using a panel of 12 antibiotics. In total, 140 E. coli isolates were collected and high resistance rates were observed for ampicillin (90.71%), cephalothin (74.28%), tetracycline (68.57%), trimethoprimsulfamethoxazole (62.14%), nalidixic acid (58.57%), ciprofloxacin (55.71%), kanamycin (52.86%), amoxicillin/clavulanic acid (52.14%), chloramphenicol (47.86%), and nitrofurantoin (40.71%). Cefotaxime resistance was observed in 27.14% of isolates, from which three avian ESBL-producing isolates were detected. Multi-drug resistance was exhibited by all avian isolates and 56.59% of bovine isolates. These findings are alarming and highlight that E. coli remains a potential threat for the transmission of antimicrobial resistance in animals, humans and even in the environment.
