THE ISOLATION AND CHARACTERISATION OF A NEWCASTLE DISEASE VIRUS FROM AN EXOTIC PARROT

Abstract
SUMMARY A Newcastle disease virus was isolated from a salmon-crested cockatoo (Cacatua moluccensis) illegally introduced into Australia. Viral-characterisation and chickentransmission studies indicated that the isolate, G5320/1, was a lentogenic pathotype. It caused a severe respiratory disease in chickens exposed oronasally at 1-day old and in chickens housed at 1 day of age with chickens infected with Newcastle disease virus. No harmful effects were detected in 5-week old chickens inoculated intravenously or oranasally with the virus.
