Abstract
Pyrexia, anemia, tachypnea, palpitation, and hemoglobinuria were manifested in experimental, as well as spontaneous, cases of eperythrozoonosis in sheep. Eperythrozoon ovis was polymorphic in blood smearsprepared from spontaneous cases and identified electron microscopically.
In the case of artificial infection E. ovis appeared in the blood 15 days after inoculation, but disappeared almost completely at the climax of anemia. It seemed to have multiplied mainly in the bone marrow before it did in the peripheral blood.
