Molecular and Antigenic Characterization of Bangladeshi Isolates of Infectious Bursal Disease Virus Demonstrate their Similarities with Recent European, Asian and African Very Virulent Strains

Abstract excerpt

Three isolates of infectious bursal disease virus (IBDV), obtained from chickens in Bangladesh in 1999 and designated as BD 1/99, BD 2/99 and BD 3/99, were characterized. In an antigen capture enzyme-linked immunosorbent assay using a panel of VP2-specific neutralizing monoclonal antibodies (mAb), all three isolates showed a mAb-binding profile similar to that of very virulent IBDV (vvIBDV) strains. In contrast...
