ABSTRACT
A cross-sectional study was conducted to determine the seroprevalence of anti-Rickettsia spp. in dogs from Belo Horizonte, MG. For this purpose, serum samples from 453 dogs were collected during the rabies vaccination campaign and tested by the indirect immunofluorescence assay (IFA) using five antigens Rickettsia bellii, Rickettsia amblyommii, Rickettsia rickettsii, Rickettsia parkeri, and Rickettsia felis. The endpoint titer reacting with each antigen was determined and serum was considered positive if it reacted at the 164 dilution. Serum showing titer for a Rickettsia species at least four-fold higher than that observed for any other Rickettsia species was considered homologous to the first Rickettsia species. Only three (0.66%) dogs reacted positively to at least one Rickettsia species and one serum showed to be homologous to R. rickettsii. These results showed a low prevalence of antibodies anti-Rickettsia spp. in dogs from Belo Horizonte city. However, other serosurvey needs to be performed for surveillance of the endemic status of the disease in the municipal district.
