Plain-English summary
A study in the Eastern Amazon of Brazil found that many dogs are exposed to tick-borne diseases like ehrlichiosis and babesiosis. Blood samples from 129 dogs showed that 42.6% had antibodies for Babesia canis vogeli, which was more common in urban dogs (59.6%) compared to rural dogs (29.1%). About 16.2% had antibodies for Ehrlichia canis, with similar rates in both urban and rural dogs. Rickettsia species were found more often in rural dogs (40.3%) than in urban ones (21.1%). This highlights the need for pet owners to be aware of tick-borne diseases in their dogs, especially in these regions.

Abstract
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 Santarém 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.
