Abstract
Infectious bursal disease virus (IBDV) is one of the most important viral pathogens of chickens. This virus causes great economic losses to the poultry industry due to factors like high mortality rates and poor growth performance of the affected chickens. Despite the intensive application of different vaccines against IBDV, several outbreaks are still emerging in many parts across the globe. This chapter highlights some important basic and clinical information related to IBDV. Further, the pathological changes and the molecular pathogenesis of IBDV infection in chicken have been discussed. In addition, recent advances on the vaccine preparation and prophylaxis against the IBDV infection have been touched. There is a need for further research to find the most appropriate vaccine and control measures against the IBDV infection in chickens.
