RESUMO

Canine babesiosis is endemic in Brazil, and transmitted by the tick Rhipicephalus sanguineus. This study aims to determine the occurrence of infection by Babesia spp., identify the infective sub-species, characterize the main hematological and biochemical changes, and determine the frequency of co-infections with other hemoparasites in the peri-urban region of Brasília ( Fercal and Lago Oeste), Distrito Federal. We used 187 blood samples from dogs, being 124 from Fercal and 63 from a rescue shelter in Lago Oeste. The animals were divided into three groups: G1 (dogs only infected by Babesia spp.), G2 (dogs infected with Babesia spp. and co-infections with Hepatozoon sp., Ehrlichia sp. and Leishmania sp.) and G3 (dogs negatives for Babesia spp.). The occurrence of Babesia spp. infection was found 22.99%. B. canis vogeli and B. canis rossi were identified as the causative agents of babesiosis in this regions, the latter until now had not been reported in Brazil. We observed the following hematological and biochemical changes in infected dogs anemia (65.78%), monocytosis (89.47%), thrombocytopenia (60.52%), hyperprotein (68.42%), hypoalbumin (60.52%) and decreased albumin / globulin. This study concluded that canine babesiosis is endemic in peri-urban areas of Brasilia, two sub-species (B. canis vogeli e B. canis rossi) infect dogs in this region, and infection with B. canis rossi is present in the region of Brasilia.
