title: Failure to demonstrate viscerotropic velogenic Newcastle disease in psittacine birds in the Republic of the Philippines.
abstract: Birds on the islands of Luzon, Mindanao, and Palawan in the Republic of the Philippines were surveyed for viscerotropic velogenic Newcastle disease (VVND). Virus isolation was attempted on 728 cloacal samples from native and exotic psittacine birds, non-psittacine birds, and domestic chickens and ducks. A VVND virus isolate was obtained from a single domestic chicken that had exhibited ocular discharge and diarrhea 3 days before sampling. All other birds were negative for VVND.
