Assessment of Newcastle and infectious bronchitis pathogens, and Salmonella spp. in wild birds captured near poultry facilities

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.
