Abstract:
A study was conducted to evaluate the sero-prevalence of IBV (infectious bronchitis virus) in Giriraja birds that were supplied to the farmers in and around Puducherry from the breeder stock of the poultry unit of ILFC, RIVER. Serum from adult, healthy Giriraja birds, previously unvaccinated for IBV were tested for IBV antibodies using commercial IBV Enzyme-Linked Immunosorbent Assay (ELISA) kit. For comparison of the IBV antibody status, serum was sampled from healthy adult layers, vaccinated against IB, from various farms in Namakkal. All the serum samples collected from unvaccinated Giriraja birds in Puducherry (n=120) were negative for IBV antibody. Of the serum samples from vaccinated birds at Namakkal (n=184), 95% had antibodies against IBV. The findings indicated that IBV was not prevalent in Giriraja birds in Puducherry. Regular monitoring of sera from flocks for IB antibody titres may help to detect the exposure to the virus in unvaccinated flocks or indicate the level of vaccine response in vaccinated flocks.
