Abstract: The serum antibody levels in village chickens reared in and around Nsukka, Southeast Nigeria was studied using Indirect Haemagglutination (IHA) test. A total of 484 serum samples were collected from these predominantly unvaccinated village chickens and examined. Result showed a high seroprevalence of 88.4%. This indicates the endemic nature of this infection among the village poultry population in the study area. These village poultry are by this result being incriminated as an important factor in the epidemiology of the disease in commercial and exotic chickens where frequent outbreaks occur. Education of the rural farmers and mass immunization of the villagers chickens were suggested as a way of reducing the maintenance and dissemination of the virus in the environment.
