Babesiosis or "Tick fever" is a feverish and anemic disease, produced in domestic and wild animals and occasionally in humans by species of the genus Babesia, which are intra-erythrocytic protozoans. Ehrlichiosis and anaplasmosis are called a group of bacterial infections transmitted by hard ticks (Ixodidae), which affect humans and animals. They are of universal distribution, and are related to several species of the genera Anaplasma and Ehrlichia (family Anaplasmataceae). Fever of unknown origin in patients with a history of travel to endemic areas of Ixodes results in a high index of suspicion for the search for Babesia, Borrelia and Ehrliquia infections, since they can occur simultaneously, particularly with these last two genera. We report a case of female patient, 49 years old, from Tumeremo Bolívar state, mining occupation, who consulted for fever with chills, headache and myalgias predominant in lower limbs. He entered intensive therapy for respiratory distress and septic shock. Malaria was ruled out by gross negative strains, blood culture and urine culture showed no bacterial growth. White-coat smears were positive for monocytic Ehrliquia and Babesia bigemina. The patient progressed satisfactorily after treatment with Doxycycline, clindamycin plus meropenem. The purpose of this report is to make the medical community aware of the existence of ehrlichiosis as an emerging clinical entity in our country and the possibility of coexisting with other microorganisms that share the same vector in order to consider timely empirical treatment in patients with factors risk in rural areas.
