Bovine babesiosis is a disease caused by Babesia bovis and Babesia bigemina, as part of the tick fever complex and relevant in the Northwest of Argentina. Clinical occurrence of this illness is uncommon in young cattle, considered resistant to babesiosis. This work described two cases of cerebral babesiosis in calves of different beef herds. Jaundice, splenomegaly, severe cerebral congestion and hemoglobinuria was observed at necropsy. Babesia bovis-like structures were identified in cerebral and blood smears Giemsa stained and confirmed by molecular techniques. Different situations were recognized following the evaluation of the epidemiological status of both herds: the first one was a single case in a herd with enzootic stability for babesiosis, with scarce clinical cases despite high rates of B. bovis transmission; the other case was in a context of outbreak with high level of mortality within a herd susceptible to babesiosis. Clinical babesiosis was not previously described in calves from Argentina. Babesiosis must be taken into account for the differential diagnosis in calves from endemic areas of the disease.
