Detection of extended-spectrum β-lactamase (ESBL) producing Escherichia coli in chickens

Objective: Indiscriminate use of antibiotics in poultry farms increases the chance antibiotic-resistant and ESBL producing bacteria Bangladesh. Therefore, study was undertaken to detect extended-spectrum β-lactamase (ESBL) Escherichia coli (E. coli) chickens. 
 Materials methods: A total 60 cloacal swab samples (20 from commercial layer, 20 broiler, Sonali chickens) were collected Rajshahi district The E. isolated these identified based on cultural, staining, biochemical characteristics. disk diffusion method used assay antibiotic-resistant/sensitivity patterns coli. Phenotypic detection also done. Results: prevalence chickens 61.67% Bangladesh, where 60%, 65% a chickens, respectively. antibiotic sensitivity layer showed 100%, 80%, 50%, 40%, 40% resistant amoxicillin, tetracycline, cefotaxime, ciprofloxacin, ceftazidime, broiler 90%, 70%, In phenotypic detection, overall 43.33%, respectively Conclusion: These results indicated that are potential reservoir for their resistances obviously significant. findings will help us make proper guideline treatment, prevention, control prevalent Bangladesh
