Bovine babesiosis (Babesia bovis infection) in Zambia.

Two cases of Babesia bovis, a parasite associated with the tick Boophilus microplus, are reported for the first time from the central part of Zambia. It is concluded that infected B. microplus ticks are occasionally introduced into central Zambia by tick-infested cattle from the north-eastern part of the country where B. bovis is endemic. The spread of B. microplus in Southern Africa in a westward direction is discussed and related to the epidemiology of bovine babesiosis in Zambia.
