E-mail: mararrps@yahoo.com.br Ehrlichia canis, is the primary etiologic agent of canine monocytic ehrlichiosis. The disease is mainly transmitted by the brown dog ticks Rhipicephalus sanguineus in different endemic regions of Brazil. The purpose of this study was determinated using the Nested Polymerase Chain Reaction (nested-PCR) the prevalence of Ehrlichia canis in 85 dogs, regardless of race, age, sex or health status, treated at the Veterinary Hospital of Federal University of Espirito Santo, in Alegre-ES and evaluate its correlation with the presence of morulae and thrombocytopenia. It was observed that 1.17% of the samples were positive by blood smear, for the presence of morulae. However, the nested-PCR showed 5.88% positivity of samples. And 17.64% samples showed thrombocytopenia. By analyzing all the techniques, it was concluded that the introduction of diagnostic techniques such as nested-PCR is an important method for aid in early diagnosis of pathologies.
