Abstract
An isolate of NDV from Japanese quail was revived in six weeks old chi cks, serially passaged in embryonated hens eggs for ten times and the amnio-allantoic fluid collected from the infected eggs was tested for HA titre (1024), Egg lethal dose (10log ELD50;5.75/0.01 ml). Virulence characters based on MDT (57 hrs), ICPI (1.78), and IVPI (2.53) proved the isolate to be velogenic. The 10log TCID50 titre in BHK21 cell lin e at 5th and 10th passage levels were 4.25/50mul and 5.25/50mul respec tively.
