Resumo

Preservation of high production levels in the Brazilian poultry industry requires some biosafety measures.Among these, poultry facilities must be built distant from cities and in places without intense human traffic.Thus, poultry facilities are built next to forests, which work like physical barriers.However, forests are inhabited by wild birds that may serve as carriers of avian pathogens (Hubalek, 2004), such as Newcastle disease virus (NDV), infectious bronchitis virus (IBV), and Salmonella spp.Infection of poultry with these pathogens may lead to economical losses.In Brazil, NDV has not been isolated from freeliving birds but from captive birds in Rio de Janeiro (Couceiro et al., 1990), greater flamingo (Phoenicopterus ruber) (Doretto Jr. et al., 1999a), and ostrich (Struthio camelus) (Doretto Jr. et al., 1999b).As for IBV, it has been isolated in Brazil from exotic birds including domestic guinea fowl (Miyaji, 1996) and Japanese quail (Di Fabio et al., 2000).Numerous serotypes of Salmonella spp.have been isolated from many species of wild birds in the world.In Brazil, has been isolated S. Typhimurium from great egret (Ardea alba) (Freitas et al., 1977) and S. Typhimurium serotype S. enterica subsp.enterica 4 and 12 and S. enterica subsp.enterica 4 and 12 from rock pigeons (Marciano, 2004).Considering viral (NDV and IBV) and bacterial (salmonellosis) diseases, which can affect avians and represent a risk for public health, the present Recebido em 9 de dezembro de 2009 Aceito em 19 de fevereiro de 2010
