| Abstract: | Pahar, B. and Rai, A., 1997. The characterization of infectious bursal disease virus strains/isolates from field outbreaks in India. Veterinary Research Communications, 21 (4), 289-301Three infectious bursal disease virus (IBDV) isolates were adapted to culture in chick embryo fibroblast cells in which they produced a cytopathic effect. The isolates were identified as IBDV by virus neutralization tests using a standard hyperimmune serum against infectious bursal disease, physicochemical properties and their pathogenicity in chick embryos and chicks. The IBDV S394 strain was antigenically different from IBDV S194/IBDV S494 as well as from the IBDV Intermediate Georgia strain, one of the vaccine strains in use in India. |
