Abstract

In recent years, some outbreaks of skin lesions suspected to be avian pox were observed in a farms layer chicken in Yogyakarta Province, Indonesia. This article reports a confirmed case of avian pox virus from three-layer chickens and a pigeon kept in same farm area. Both chickens and pigeon showed nodular lesions on unfeather head skin and fibro-necrotic lesions on the mucus membrane of the oral cavity. Avian pox virus was propagated from nodular and fibro-necrotic lesions by inoculation into the chorioallantoic membranes (CAM) of 10-days-old specificpathogen-free chicken embryos for 5-7 days. The CAM was examined to observe the pock lesions. The tissue samples from nodular lesions were stained with Hematoxylin-Eosin stain for histopathological analysis. For PCR, after DNA extraction, a 578-bp fragment of avian pox virus from 4b core protein gene was amplified. The data were analyzed descriptively. Both chickens and pigeon samples were positive for avian pox virus on propagation, histopathological, and PCR examination, respectively. The conclusion of this report there is potential transmission of avian poxvirus between chickens and pigeon, so other birds should not be kept inside the farm.
