title: Biological characterisation of an Indian isolate of egg drop syndrome-76 virus.
abstract: An isolate of egg drop syndrome-76 virus replicated best in primary chicken embryo liver cells and less well in duck embryo liver cells, duck embryo fibroblast cells and chicken embryo kidney cells. The cytopathic effect in chicken embryo liver cells was marked by the presence of round and refractile cells and detachment of cells from the glass surface. The intranuclear eosinophilic inclusion bodies were observed by 24 to 48 hours after infection. No virus multiplication was observed in primary quail embryo fibroblast cells, chicken embryo fibroblast cells or mammalian cells like Vero, BHK-21 and MDBK. Duck embryos supported the maximum growth of the virus, with allantoic fluid having the highest haemagglutinin titre, followed in order by chorioallantoic membrane, skin and internal organs. Chicken and quail embryos did not support the growth of the virus.
