MOURA, Anderson Barbosa de et al. Neospora spp. antibodies in horses from two geographical regions of the state of Santa Catarina, Brazil. Rev. Bras. Parasitol. Vet. [online]. 2013, vol.22, n.4, pp.597-601. ISSN 1984-2961.

The aims of this study were to determine occurrences of Neospora spp. IgG antibodies in horses from two geographical regions of the state of Santa Catarina, southern Brazil, and identify risk factors for infection. Analyses were performed on 615 samples using the immunofluorescent antibody test (IFAT ≥ 1:50). Out of the 615 samples, 25 (4.1%) were positive for Neospora spp. The titers for Neospora spp. were distributed as follows: 1:50 (13), 1:100 (eight), 1:200 (three) and 1:400 (one). Out of the 311 samples taken in the mountain region, eight were positive (2.6%). Among the samples from the coastal region (304), 17 had Neospora spp. antibodies, thus indicating occurrence of 5.6%. Although no statistically significant difference was observed (P = 0.06704), the prevalence among animals of the coast was 2.2 times higher than that of the mountain region. Contact with dogs and/or cattle (P = 0.007596) were identified as risk factor for Neospora spp. infection.

Keywords : Neospora spp.; equines; IFAT; epidemiology.
