[Ehrlichiosis in dogs: literature review and case description].

: A case of E. canis in a 7 year old intact female bearded collie is described and possible clinical signs of Ehrlichiosis are discussed. Non-specific findings included elevated rectal temperature, depression and anorexia. Additional findings were generalized lymphadenomegaly, myalgia and painful swollen joints. Significant changes in the CBC were leucopenia and thrombocytopenia. The positive E. canis titer of 1:40 and rising titer to 1:160 were specific for Ehrlichiosis. Doxycycline and prednisolone were needed to obtain clinical remission, which underlines, that immune-mediated processes are important in the pathogenesis of Ehrlichiosis.
