Brazil is one of the world's largest countries with a rich diversity of wildlife, including resident and migratory wild birds, which may be natural reservoirs of the Newcastle disease virus (NDV). Because Brazil is a major global exporter of chicken meat, the emergence of such a disease may have a huge negative impact not only on the economy due to trade restrictions and embargoes, but also on the quality of life of the population. Samples were collected from 1,022 asymptomatic domestic and wild birds from the Brazilian coast and the Amazon region using tracheal/cloacal swabs and tested by RT-qPCR. The results showed 7 (0.7%) birds were positive for NDV. The positive samples were then isolated in embryonated chicken eggs and their matrix protein genes were...

SURVEILLANCE FOR NEWCASTLE DISEASE VIRUS, AVIAN INFLUENZA VIRUS AND MYCOPLASMA GALLISEPTICUM IN WILD BIRDS NEAR COMMERCIAL POULTRY FARMS SURROUNDED BY ATLANTIC RAINFOREST REMNANTS, SOUTHEASTERN BRAZIL Rev. Bras. Ciênc. Avic.
Guimarães,MB; Hurtado,R; Bello,CP; Vanstreels,RET; Ferreira,AJP.
ABSTRACT The geographic overlap between areas of Atlantic rainforest and human activities allows interactions to occur between humans and wild and domestic animals. Despite the great importance of the domestic animal-wildlife-human interface that occurs at poultry farms in terms of public health, economic production and wildlife conservation, there are few studies in Brazil examining the distribution and health of wild birds that interact with poultry farms. From January to December 2010, mist nets were used to capture 166 free-ranging birds that were within close proximity to three poultry farms in Atlantic rainforest remnants in south-eastern Brazil. The species composition was examined, and molecular methods were used to test for avian influenza virus,...
