Occurrence of antibodies against Neospora caninum in wild pigs (Sus scrofa) in the Pantanal, Mato Grosso do Sul, Brazil
Serum samples from 83 free living wild pigs (Sus scrofa) from the Nhecolândia region, Pantanal do Mato Grosso, Brazil, were examined for the presence of antibodies against Neospora caninum by means of the indirect fluorescence antibody test (IFAT) with a cut off of 50. Antibodies were present in 10.8%, with titers of: 1:200 in one animal, 1:400 in four and 1:800 in four. Analysis using the χ2 test showed an association between sex and presence of antibodies, with females showing occurrence of 20.5% and males 2.3% (p = 0.017). No association was found between age and occurrences of antibodies against this parasite. This was the first observation of N. caninum antibodies in Brazilian wild pigs from Pantanal.
