ABSTRACT
Objective: To observe other hemoprotozoan diseases with canine ehrlichiosis and to evaluate the clinical and hematological aspects of dogs naturally infected with ehrlichiosis with other hemoprotozoan diseases.Methods:Blood was collected for hematological value and Giemsa stained blood smear was made for diagnosis of Ehrlichia sp. and other hemoprotozoan parasites from naturally infected dogs. Case history was taken from the owner and clinical signs and symptoms were noted.Results:A total of 47 cases of ehrlichiosis in dogs were reported with babesiosis (8.51%) and hepatozoonosis (6.38%) hemoprotozoan diseases. Ehrlichia canis, Ehrlichia ewingii, Brucella canis,Babesia gibsoni and Hepatozoon canis were observed under oil immersion lense of microscope in Giemsa stained peripheral blood smears. Marked anaemia and neutrophilic leukocytosis were observed.Conclusions:The results of this study stated that clinical and haematological changes occurred in canine ehrlichiosis with babesiosis and hepatozoonosis due to parasitemia. In mixed infection, the disease more severe, and also it depended on immunity of animals. Babesia gibsoni andHepatozoon canis with Ehrlichia sp. were first reported from West Bengal state of India by this study.
