Co-infections by Leishmania (L.) chagasi, Trypanosoma evansi, Toxoplasma gondii and Neospora caninum in dogs were investigated. Amastigotes forms of Leishmania spp. were detected by cytopathological analysis of lymph nodes in 46,42% (39/84) of dogs. In a male dog, adult, without defined breed, from rural area and positive for Leishmania, were observed flagellated forms of T. evansi in blood smear. By immunofluorescence antibody test, 5,95% (5/84) of dogs were considered reactive to T. gondii, with titer equal to or higher than 1:64, while 3,57% (3/84) were reactive to N. caninum, with titer ≥1:50. Among the animals with visceral leishmaniasis, one showed positive serological response to T. gondii and two for N. caninum. All dogs reactive to N. caninum were from rural area and the predominance of infection by T. gondii was in dogs from urban area. A young male dog from the rural area and seropositive for T. gondii showed Ehrlichia spp. morulae in the cytology and positive reaction for canine distemper virus. Thus, further studies are needed to assess the epidemiology of these infections in canine population, especially with respect to the reservoirs of Trypanosoma spp. in rural areas.

Canine Distemper is a contagious, severe and multisystemic disease caused by a virus from Morbillivírus genus. The virus is distributed worldwide and it presents a high lethality rate, affecting mainly dogs. The diagnosis is based on clinical signs associated with hematological fi ndings. The observation of Lentz bodies in erythrocytes and leukocytes is the defi nitive diagnosis for the disease. The aim of this work was to test the hypothesis that the hematological profi le in dogs positive for canine distemper differs according to blood cell type presenting Lentz bodies. For this purpose, 25 dogs positive for the disease were evaluated at the Veterinary Hospital “Luís Quintiliano de Oliveira” UNESP, Araçatuba city. The diagnosis was based on the observation of Lentz bodies in blood smears. Fromthe total, 64% of dogs presented anemia, 16% leucopenia and 12% leukocytosis. Lymphopenia occurred in 76% of dogs. Viral inclusions were observed solely in neutrophils (32%), lymphocytes (28%) and erythrocytes (12%). Concomitant observation occurred in lymphocytes and erythrocytes (4 %), in lymphocytes and neutrophils (12%), in neutrophils and monocytes (4%) and in neutrophils and erythrocytes (4%). In an isolated case Lentz bodies were observed simultaneously in neuthrophils, monocytes and lymphocytes. In conclusion, hematological profi le is not associated with the presence of viral inclusion in a particular cell type.
