PREVALENCE OF SALMONELLA ASSOCIATED WITH GOATS IN BANGLADESH
Abstract
Salmonellosis is one of the life threating diseases of goats in Bangladesh. Therefore, the present study was designed to study the prevalence of Salmonellosis, and the isolation and characterizations of the Salmonella spp. from apparently healthy and diarrheic goats. A total of 47 faecal samples was collected from selected places and cultured onto different prescribed media to isolate the Salmonella. In this study, 12.76% (6/47) of the samples were found to be positive for Salmonella spp. During culture, all of the Salmonella isolates produced round, smooth, opaque, translucent, andblack colored colonies on SS agar medium. All of the isolated Salmonella spp. fermented dextrose, maltose, and mannitol with production of acid and gas but did not ferment sucrose and lactose. However, these isolates had shown negative for the Indole and Voges-Proskauer tests and positive for the Methyl-Red test. All of these isolates were subjected to a rapid plate agglutination test with polyvalent “O” (Poly ‘O’) and polyvalent “H” (poly ‘H’) antisera where positive agglutinations wereobserved. They were highly sensitive to ciprofloxacin, spiramycin, and gentamycin; moderately sensitive to oxytetracyline, streptomycin, and amoxicillin; less sensitive to sulphamethoxazole and resistant to penicillin-G. Based on the present findings, it may be concluded that the investigated Salmonella spp. from goats might be S. typhimurium, S. enteritidis, S. brandenburg, S. salford, S. newbrunswick, S. newport, or S. dublin. It was a preliminary study; therefore, further characterization is required using other serological and molecular techniques.
