RESUMO
Erliquiose canina é uma donça causada por infecção de células mononucleares pela Ehrlichia spp., riquétsias transmitida pelo carrapato que formam agrupamentos intracelulares. Com o objetivo de avaliar As alterações hematológicas em cães domésticos naturalmente infectados com Ehrlichia spp., foram realizados hemograma de 109 animais com presença de mórulas nos leucócitos em extenões de sangue coletado de capilares marginais da orelha. Observou-se com maior frequência anemia (77,98%) trombocitopenia (87,15%), eosinopenia (64,22%), desvio nuclear de neutrófilos para a esquerda (50,46%), leucopenia (24,77%) e linfopenia (22,02%). A anemia de maior frequência foi do tipo normocítica normocrômica quanto à morfologia e arregenerativa quanto à resposta da medula óssea. Concluiu-se que, embora não específicos, trombocitopenia, anemia arregenerativa, eosinopenia e desvio nuclear de neutrófilos para a esquerda, são achados frequentes na erliquiose canina.
Canine ehrlichiosis is a disease trnsmitted by tick caused by na a obligate, intracellular parasite, Ehrlichia spp., rickettsial agent, which form intracellulars groupings. With the objective to evaluate the hematologic alterations in domestic dogs naturally infected by Ehrlichia spp., hemograms were put into practice in 109 animals with the presence of morulae in the leukocyte in blood extensions collected from margins capillarys of the ear. The hematologic alterations observed with larger frequency were: anaemia (77.98%), thrombocytopenia (87.15%), eosinopenia (64.22%), nuclear deviation of neurophils to the left (50.46%), leukopenia (24.77%) and lynphopenia (22.02%). Among the anemic animals, the anaemia with larger frequency was the one of type normocytic normochromic as for the morphology and nonregenerative as for the answer of the bone medulla. It is ended that, although not specific, trombocytopenia, nonregenarative anaemia, eosinopenia, nuclear deviation of neutrophils to the left, they are found frequent in the canine ehrlichiosis.
