Detection of Newcastle Diseases antibodies in birds in Jos, Bukuru and Environs using Agar-Gel Precipitation test

摘要

Newcastle Disease Virus (NDV lasota) antibodies were surveyed. A serological study of 500 sera from local chicken, turkey, ducks and guinea fowl was carried out to determine the prevalence of Newcastle disease using Agar-gel precipitation technique. Samples were obtained from chickens slaughtered in Jos, Bukuru and environs. The samples were made up of 40 ducks, 50 turkeys, 20 guinea fowl and 390 local chickens. The precipitin antibodies were detected in ducks 7 (17.5%), turkey 12 (24.0%), guinea fowl 3 (15.0%), and local chickens 54 (13.9%). Of the 500 samples screened, a total of 76 (15.2%) were positive for NDV antibodies. Quantitative analysis of sero-positive samples in the four avian species tested yielded a range of antibody titres of 2-16. The importance of using cost effective technique for the detection of NDV carrier state in local birds has been highlighted.
