Abstract

Tick-borne diseases are diseases of great importance in the medical practice of small animals, due to the high casuistry and wide vectorial distribution in the Brazilian territory. The main agents responsible for infections in dogs are Babesia sp., Ehrlichia canis and Hepatozoon canis. Infected animals are asymptomatic or present nonspecific clinical signs, requiring the use of diagnostic tests to define the etiologic agent, and safe diagnosis. The objective of the present study was to determine the occurrence of these microorganisms in naturally infected dogs domiciled in the municipalities of Vila Velha and Anchieta, Espírito Santo, using different detection tests: polymerase chain reaction (PCR), serology to detect antibodies against Ehrlichia canis and research of hematozoa in blood smears. Sixty-five blood samples obtained by venipuncture of the cephalic vein of dogs were analyzed. In the PCR test, 4.62% of the animals were positive for Babesia vogeli and 1.54% for Ehrlichia canis, and the results for Hepatozoon canis were negative. In the serological test for E. canis, 90.77% of the animals were positive for the presence of antibodies, and in the research in blood smear slides, 3.02% presented other hemoparasites. The results indicate the dispersion of these hemoparasites in the canine population of the study region, however with low occurrence. The PCR test proved to be the most sensitive, in which Babesia vogeli was the most observed agent.
