IDENTIFICATION AND ANTIMICROBIAL SUSCEPTIBILITY OF SALMONELLA GALLINARUM ISOLATED FROM FOWL TYPHOID OUTBREAK IN BACKYARD VANARAJA FOWL

From a disease outbreak among Vanaraja fowl, an indigenous Indian Breed reared by backyard system in Jhargram, West Bengal, Salmonella Gallinarum was isolated and characterised. The outbreak occurred among 6-8 day old chicks. A total of 150 birds died in a span of 5 days. Salmonella Gallinarum were identified and confirmed by standard bacteriological methods and presence of invasion ( invA) gene was detected by PCR. The isolates were susceptible to 15 common antimicrobials in vitro. Although chemotherapy may be effective, outbreaks of fowl typhoid in backyard poultry warranted precise control policy
