The serological status of porcine parvovirus (PPV) infection and transmissible gastroenteritis virus (TGEV) infection were determined in swine from extensive raising systems in the state of Goiás, Brazil. Ninety-seven serum samples were collected from animals in 12 extensive farms distributed in six cities located nearby Goiânia, GO, and 74 samples were collected from animals in a slaughterhouse in Goiânia, GO. For the PPV-specific antibody detection, the hemaglutination inhibition test (HI) was used; and for TGE antibody detection, the serum neutralization test was performed. Results showed that 25 out of the total 171 (14.4%) analyzed sera were positive for PPV antibodies, and the HI titers varied between 256 to 4,096. None of the 136 serum samples analyzed for TGEV was positive. This is probably the first study that detected PPV and TGEV-specific antibodies in swine herd in the state of Goiás. Data suggest that PPV but not TGEV circulated between and among this population of swine in that state.(AU)
