Leishmaniasis are diseases of a zoonotic nature with importance in public health, which has as a protozoa n etiological agent of the genus Leishmania spp It has a heteroxhenic biological cycle, with a phlebotomin e vector and among the hosts stands out the dog as the main reservoir, but it can affect wild mammals and man. In Brazil there is a description of the occurrence of tegumentary leishmaniosis and visceral leishmaniosis. The tegumentary form presents high casuistics in humans in the northern region. The present work evaluated 152 hematological samples obtained by peripheral venopuncture of dogs serororreagents to the DPP in the municipalities of Manaus/AM and Presidente Figueiredo/AM, endemic regions for t egumentary leishmaniosis. Erythrogram and leukogram were performed using a traditional manual technique and the differential leukocyte count was performed under optical microscopy, in immersion lens (100x). Of the 152 samples 32 were reagents for Leishmania spp. However, blood count, erythrocytes values, globular volume, leukocytes, platelets and total plasma protein showed no statistical difference between reactive and non reactive animals (p>0.05). However, dogs with leishmania spp may remain asymptomatic not presenting suggestive hematological alterations, since the most frequent clinical manifestation is dermatological. It is concluded that PPD is useful tool for screening leishmania sp p. although it does not present specificit y, false positives may occur. The hematological carcaterization of the samples studied did not present diagnostic indication. Thus, further studies are needed to investigate leishmania spp species involved in infections in domestic dogs in the Amazon r egions and their relationship with cases of human tegumentary leishmaniasis.
