Abstract
Some observations are recorded on blood parasites of sable antelopes. Of 124 blood smears from South Africa and Zimbabwe 7 were positive for a Babesia sp., identified as B. irvinesmithi Martinaglia 1936. Of the smears, 70 were positive for theilerial piroplasms, while 1 smear had macroschizonts (with cytomeres) and microschizonts of a Theileria (= Cytauxzoon) sp.; 1 smear was positive for an Anaplasma sp. Attempts to isolate the Babesia sp. by subinoculating blood from sable to splenectomized and intact sable and splenectomized cattle were unsuccessful. Attempts to infect sable with B. bovis and B. bigemina were likewise unsuccessful. Theilerial piroplasms reached high levels in a splenectomized sable but could not be transmitted with blood to cattle. The Anaplasma sp. was infective for sheep but not for cattle.
