Abstract:
A case of bovine cerebral theileriosis was confirmed at autopsy on a farm where 4 animals out
of 70 died. All were less than 2 years old and all showed nervous signs.
Serologically, no evidence was found of Theileria mutans or the Theileria parva group in young
animals born on the farm. Six out of 13 calves 6-9 months of age were, however, serologically positive
for Theileria? taurotragi and it was concluded this species was the probable cause of death of
the 4 animals.
