%X Canine ehrlichiosis and babesiosis are the most prevalent tick-borne diseases in Brazilian dogs. Few studies have focused attention in surveying tick-borne diseases in the Brazilian Amazon region. A total of 129 blood samples were collected from dogs living in the Brazilian eastern Amazon. Seventy-two samples from dogs from rural areas of 19 municipalities and 57 samples from urban stray dogs from Santar¨¦m municipality were collected. Serum samples were submitted to Indirect Immunofluorescence Assay (IFA) with antigens of Babesia canis vogeli, Ehrlichia canis, and six Rickettsia species. The frequency of dogs containing anti-B. canis vogeli, anti-E. canis, and anti-Rickettsia spp. antibodies was 42.6%, 16.2%, and 31.7%, respectively. Anti-B. canis vogeli antibodies were detected in 59.6% of the urban dogs, and in 29.1% of the rural dogs (P < 0.05). For E. canis, seroprevalence was similar among urban (15.7%) and rural (16.6%) dogs. For Rickettsia spp., rural dogs presented significantly higher (P < 0.05) prevalence (40.3%) than urban animals (21.1%). This first study on tick-borne pathogens in dogs from the Brazilian eastern Amazon indicates that dogs are exposed to several agents, such as Babesia organisms, mostly in the urban area; Spotted Fever group Rickettsia organisms, mostly in the rural area; and Ehrlichia organisms, in dogs from both areas studied. Ehrliquiose canina e babesiose canina s o as doen as parasit¨¢rias transmitidas por carrapatos de maior preval¨ºncia em c es do Brasil. Poucos estudos pesquisaram doen as transmitidas por carrapatos na regi o da Amaz nia brasileira. Um total de 129 amostras de sangue foram colhidas de c es da Amaz nia oriental brasileira. Setenta e dois c es eram de ¨¢reas rurais de 19 munic¨ªpios do Estado do Par¨¢, e 57 amostras foram colhidas de c es errantes vadios da ¨¢rea urbana do munic¨ªpio de Santar¨¦m-PA. As amostras de soro foram submetidas ao ensaio de imunofluoresc¨ºncia indireta, com ant¨ªgenos de Babesia canis vogeli, Ehrlichia canis, e seis esp¨¦cies de Rickettsia. A frequ¨ºncia de c es com anticorpos anti-B. canis vogeli, anti-E. canis, e anti-Rickettsia spp. foi de 42,6%, 16,2% e 31,7%, respectivamente. Anticorpos anti-B. canis vogeli foram detectados em 59,6% dos c es urbanos, e em 29,1% dos c es rurais (P < 0.05). Para E. canis, a soropreval¨ºncia foi parecida entre os c es urbanos (15,7%) e rurais (16,6%). Para Rickettsia spp., c es rurais apresentaram preval¨ºncia (P < 0.05) significativamente maior (40,3%) do que os c es urbanos (21,1%).
