1 Dec 2006
Abstract excerpt
Fourteen pigeon-origin Newcastle disease virus (NDV) isolates were obtained from sick pigeons in China between 1996 and 2005. The mean death time (MDT) of embryonated eggs and the intracerebral pathogenicity indices (ICPI) were tested to determine the virulence of the field isolates. The result indicated that most isolates were proved to be mesogenic (MDT 60-90 hr and ICPI > 1.2). The main function regions of F...
