2017

Serum samples from 116 horses and 47 dogs from the municipality of Paulicéia, in the state of São Paulo, Brazil, were examined for anti-Toxoplasma gondii, -Neospora spp. and -Sarcocystis neurona antibodies by means of the indirect fluorescent antibody test (IFAT). The results showed that only one horse was seropositive for T. gondii (0.9%) and anti-Neospora spp. antibodies were detected in three out of the 116 horses tested (2.6%). However, 27 horses showed antibodies against S. neurona (23.8%). Amongst the serum samples from the dogs, 10 out of the 47 dogs showed antibodies against T. gondii (21.3%) and three dogs showed antibodies against Neospora caninum (6.4%). This study reports that in the municipality of Paulicéia dogs in both the rural and the urban area were exposed to T. gondii and N. caninum, while horses in the rural area were exposed to all three protozoa studied, with high occurrence of anti-S. neurona antibodies.
