Abstract
Brazilian spotted fever (BSF) is a zoonosis caused by spotted-fever group Rickettsiae that is transmitted to humans through tick bites. Dogs and horses are considered to be sentinel animals for this disease. In this study, a serological survey was carried out among horses apprehended by the governmental animal control service of the Federal District, Brazil. Serum samples were obtained from 122 horses over a one-year period. Through the indirect immunofluorescence antibody assay (IFA) for Rickettsia rickettsii anti-IgG antibodies, 21 samples were found to be positive, with titers ranging from 1:64 to 1:512. This demonstrates that the agent presents silent circulation in the Federal District.
