Abstract:

Objective: The present study aimed to investigate the prevalence of Salmonella and their antibiotic resistance pattern against two commonly used antibiotics: ciprofloxacin and ceftriaxone in marketed live chickens in a live birds market.  Materials and Methods: The study was conducted on live Sonali chickens (crossbred of Fayoumi female and Rhode Island Red male). Cloacal swabs were collected from 50 randomly selected live birds from 5 retail sellers (10 samples/seller) at Jhawtola live birds’ market, Chattogram, Bangladesh. Culture and biochemical tests were used to identify Salmonella. Positives samples for Salmonella were further tested for antibiogram by disc diffusion method. Results: Salmonella was identified from 28 (56%) of samples by culture and biochemical test. Among the positive isolates, 27 (96.42%) samples exhibited resistant to ceftriaxone, and 20 (71.42%) samples were to ciprofloxacin.  Conclusion: The result of this study indicates there is a high prevalence of Salmonella in marketed local chicken and are resistant to ceftriaxone and ciprofloxacin which has economic importance as well as a public health concern. Awareness should be increased to prevent random use of antibiotics and provision of strict biosecurity measures.
