- Abstract
We conducted a seroepidemiological study on the occurrence of anti-Sarcocystis spp. and anti-Toxoplasma gondii antibodies in dogs from family farming properties in the municipality of Ji-Paraná, Rondônia. Blood samples were collected from apparently healthy dogs between September 2012 and November 2013. In total, 181 blood serum samples were analyzed using an indirect immunofluorescence assay, among which 57 (31.49%) and 20 (11.04%) were positive for anti-T. gondii and anti-Sarcocystis spp., respectively. Statistical analyses showed that the type of food fed to the dogs was associated with the occurrence of anti-Sarcocystis spp. antibodies. In contrast, age and access to bovine carcasses were the risk factors for anti-T. gondii. The high occurrence of seropositive dogs for Sarcocystis spp. and T. gondii evidences the wide distribution of these agents in the studied area, possibly due to human and animal exposure to these protozoan species. In addition, anti-T. gondii antibodies were directly proportional to dog age. The increase in the number of positive animals with age was statistically significant. Furthermore, high antibody titers (up to 800) against Sarcocystis spp. in dogs suggest the possibility of recent exposure, in addition to environmental contamination by oocysts/sporocysts eliminated by the feces of these animals.
