Infectious bursal disease is an acute and highly contagious viral disease of mostly young chickens cause by a non-envelope double stranded RNA virus belonging to a family Birnaviridae and is the second considerable threat among infectious poultry diseases. The enormous economic losses associated with the disease is due to high mortality, decreased performance, immune supression that leads to increase susceptibility to other diseases and decrease response to vaccination. The target organ of infectious bursal disease virus (IBDV) is the bursa of fabricius at its maximum development, which is a specific source for B lymphocytes in avian species. The observed clinical signs during IBD infection include high mortality, unsteady gait, ruffled feathers, urate containing diarrhoea and sudden death. The post-mortem finding includes haemorrhages in the leg and breast muscles, enlarged, edematous and hyperaemic bursa with bloody or mucoid contents. RT-PCR/RFLP is a very useful and rapid method for characterization and identification of existing and evolving strains of IBDV. Only supportive therapy, immunobooster medicines with vaccination and maintaining bio securities may combat mortalities.
