To investigate the occurrence of antibodies IgG anti-Neospora caninum and Toxoplasma gondii, blood samples were collected from 374 adult female water buffaloes originated from 14 production units located in 13 counties of the state of Pará. The sera were subjected to indirect fluorescent antibody (IFA), using titers of 200 and 64 as IFA cut off points for N. caninum and T. gondii, respectively. Hundred and fifty three (40.9%) buffaloes were sero-positive for N. caninum, with 100% of the properties being sources of infection. Four buffaloes (1.1%) in four farms were seropositive for T. gondii, and one buffalo cow (0.27%) was seropositive for the two parasites. The presence of antibodies indicates that these protozoan parasites are circulating among buffaloes from the properties studied, representing a source of infection to other animals, as well as a possible cause of reproductive disorders in this species. |
