Abstract

Ehrlichiosis is a disease transmitted by tick’s bite that affect dogs and humans caused by the species Ehrlichia canis and E. chaffeensis, respectively. These bacteria are obligated intracellular gram negatives, with a cocoid to pleomorph aspect and can infect monocytes and trigger symptoms such as high fever, anorexia, thrombocytopenia, hemorrhages, anemia, and some serious problems such as splenomegaly, hepatomegaly and meningitis. There are several diagnostic tests for ehrlichiosis such as the hematological ones that evaluate the morphology of the monocytes in search of morulae; serological tests that includes the search of anti-Ehrlichia antibodies, although they might be limited due to cross reaction with other species. In other hand, the culture of Ehrlichia species is an effective method to obtain antigens and even develop indirect immunofluorescence assays (IFA). The polymerase chain reaction offers a definitive diagnosis associated to the use of genus-specific and species-specific primers, as well as its increased sensibility and specificity, compared to the others methods. Thus, in this review, we will discuss various methods applied to the diagnosis of this disease, as well as the advantages and disadvantages that these present
