Piroplasmosis in Donkeys-A Hematological and Serological Study in Central Ethiopia

Working donkeys (n = 395) originating from three different districts of the Oromia region of Ethiopia were examined October 2009 and April 2010 for the prevalence of equine piroplasmosis between. Apart from hematological and serological examination, tick vectors were collected and determined. Intraerythrocytic stages of Theileria equi and Babesia caballi were detected in 12.2% and 1.8% of examined stained blood smears, respectively. The seroprevalence of T. equi and B. caballi was 55.7% and 13.2%, respectively. The majority of active infection coincided with anemia. Only 16 donkeys were infested with four species of hard ticks: Rhipicephalus turanicus, Rhipicephalus evertsi evertsi, Rhipicephalus pulchellus, and Amblyomma variegatum.
