Seroprevalence of infectious bursal disease virus in local chickens in Udu Local Government Area of Delta State, South East Nigeria.

Infectious Bursal DiseaseVirus (IBDV) poses a great global threat to the poultry industry. Knowledge of the occurrence of the disease is important in the design and implementation of a control program, therefore this study determines the seroprevalenceof IBDV in local chickens in Udu Local Government Areaof Delta State. 250 chickens were bled by exsanguinationand sera obtained were screened using Agar Gel Immunodiffusion(AGID) test. The seropositivity was 51.6%, which is indicates endemicity of the disease. Biosecurityand good sanitary measures are recommended. Molecular characterization of the strains should be carried out for inclusion in generic vaccines.
