Abstract in Portuguese
A Febre Maculosa Brasileira causada por riquétsias do Grupo Febre Maculosa (GFM) e transmitida por carrapatos ocorre principalmente na Região Sudeste, onde óbitos humanos são registrados. No estado do Rio de Janeiro, a letalidade devido à riquetsiose é alta, mas só recentemente investigações epidemiológicas foram realizadas, e indicaram a participação de novas espécies de ectoparasitas na circulação das riquétsias. O objetivo geral do projeto é avaliar riquétsias em ectoparasitos coletados em áreas de casos humanos de Febre Maculosa, suspeitos, compatíveis ou confirmados, em municípios do estado com focos recentemente comunicados. A detecção e análise de genes riquetsiais indicam a presença de Rickettsia bellii, Rickettsia felis e Rickettsia rickettsii, nos vetores Amblyomma cajennense, Amblyomma dubitatum, Boophilus microplus, Ctenocephalides felis e Ctenocephalides canis, sugerindo ampla distribuição geográfica de riquétsias GFM, nas regiões Serrana, Noroeste Fluminense e Médio Paraíba do estado.

Abstract in English
Brazilian spotted fever caused by spotted fever group (SFG) rickettsiae and mainly transmitted by ticks occurs in the southeast, where human deaths are recorded. In the state of Rio de Janeiro, lethality due to rickettsial infection is high, but only recently epidemiological investigations were conducted, and indicated the participation of new species of ectoparasites in rickettsiae circulation. The project's overall objective is to evaluate rickettsiae in ectoparasites collected in areas of human suspected, confirmed or compatible cases of spotted fever, in cities of the State with the recently reported outbreaks. The detection and analysis of rickettsial genes indicate the presence of Rickettsia bellii, Rickettsia felis and Rickettsia rickettsii in the vectors Amblyomma cajennense, Amblyomma dubitatum, Boophilus microplus, Ctenocephalides felis and Ctenocephalides canis, suggesting broad geographic distribution of SFG rickettsiae in the regions Serrana, Noroeste Fluminense and Médio Paraíba of the State.
