Diseases transmitted by arthropods such as Rhipicephalus sanguineus, are caused by a spectrum of pathogens. Among these are the canine monocytic ehrlichiosis and cyclical thrombocytopenia with a cosmopolitan distribution. Aiming to verify the presence of DNA of Anaplasma platys and Ehrlichia canis in ticks R. sanguineus collected in the period 2008 to 2009 of 380 infected dogs. Ticks, after maceration, were subjected to DNA extraction and then nested PCR was performed for amplification of A. platys and E. canis. Of these, 81 (29.7%) amplified DNA from ehrlichiais agents, where 38 (17.9%) amplified in E. canis and 32 (15.7%) for A. platys. The observation of two pathogens, combined with worldwide distribution of the tick R. sanguineus, demonstrates the high risk of infection with these pathogens in dogs in the city of Cuiaba.
