Abstract

The aim of this study was to investigate the presence of anti-Rickettsia spp. antibodies, the tick fauna, and the ticks that are carriers of rickettsiae of the spotted fever group (SFG). About 68 (24%) of the 283 serum samples tested by indirect immunofluorescence (IFA) reacted against the R. rickettsii crude antigen. The titers varied between 1:64 and 1:512. At the time of collection, 189 (64.5%) of the 293 dogs included in this study, were infested with ticks. Ticks classified as Rhipicephalus sanguineus and Amblyomma sculptum were identified. None of the ticks examined for SFG rickettsiae using polymerase chain reaction (PCR) were positive. The presence of the anti-R. rickettsii antibodies detected by IFA, albeit at low titers, suggests the circulation of SFG rickettsiae, which requires permanent surveillance because there are records on human fatalities related to spotted fever and to avoid any future threats to the students moving extensively in the areas near of the Rural Federal University of Rio de Janeiro.
