First detection of natural co-infection with mutated very virulent IBDV (mvvIBDV) and novel variant IBDV (nVarIBDV). [PDF]

Poult Sci
Infectious bursal disease (IBD), a globally important immunosuppressive disease of poultry caused by infectious bursal disease virus (IBDV), continues to pose a substantial threat to the poultry industry. For the past three decades, very virulent IBDV (vvIBDV), associated with high mortality, have been the predominant epidemic threat.
