Abstract

The study was conducted to clarity the prevalence of serovars and antimicrobial resistance in Salmonella isolates from chicken and environment in 24 chicken farms in Chiang Mai and Lamphun province, Thailand. Thirty seven (12.9%, 95%CI=9.0-16.7) and twenty fi ve (52.1%, 95%CI=37.4-66.7) Salmonella isolates were found from 288 chickens and 48 environment samples, respectively. Salmonella isolates were found from chicken and environment in the fi rst sampling were 28 (19.4%, 95% CI=12.9-26.0 and 8 (33.3. 95%CI=13.0-53.6), respectively. The most frequently Salmonella spp. found in chickens were Salmonella Corvalis, Salmonella Albany, Salmonella Enteritidis, and Salmonella Virchow. In contrast, Salmonella Virchow was commonly found in environment. The antimicrobial resistance test showed resistance to ampicillin in both groups. The most common pattern of the resistance was the single resistant for ampicillin. Multiple resistances to ampicillin, tetracycline, streptomycin and chloramphenicol were found but the prevalence was low (4%). In conclusion, This study indicated resistance Salmonella contamination is the problem in the chicken farms. Regulation of antimicrobial use should be implemented by the authorities. Also, the surveillance system of antimicrobial use should be done in Thailand.
