Resumo: | 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. |

Este estudo teve como objetivos investigar a presença de anticorpos anti-Rickettsia spp., a fauna de carrapatos e a ocorrência de riquétsias do grupo da febre maculosa em carrapatos coletados em caninos do município de Seropédica, estado do Rio de Janeiro. Dos 283 soros testados pela imunofluorescência indireta (IFI), 68 (24%) apresentaram reatividade contra antígeno bruto de R. rickettsii. A titulação variou entre 1:64 à 1:512. Dos 293 cães avaliados, 189 (64,5%) estavam infestados por carrapatos no momento da coleta. Foram identificados carrapatos das espécies Rhipicephalus sanguineus e Amblyomma sculptum. Nenhum carrapato examinado por meio da reação em cadeia de polimerase (PCR) apresentou-se positivo. A presença de anticorpos contra R. rickettsii pela IFI, mesmo que em baixos títulos, sugere a circulação de rickettsias do grupo da Febre Maculosa, devendo-se ter uma vigilância permanente devido ao grande trânsito de alunos nas áreas próximas ao campus da UFRRJ e ao registro da ocorrência de óbitos em humano por Febre Maculosa.
