Theileria? taurotragi: a probable agent of bovine cerebral theileriosis.
نویسندگان
چکیده
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.

BACKGROUND Bovine theileriosis results from infection with obligate intracellular protozoa of the genus Theileria. The phylogenetic relationships between two isolates of Theileria annulata, and 36 Theileria spp., as well as 6 outgroup including Babesia spp. and coccidian protozoa were analyzed using the 18S rRNA gene sequence. METHODS The target DNA segment was amplified by PCR. The PCR produ...

East Coast fever caused by Theileria parva parva has been eradicated from South Africa, but tick-borne infections with other species of Theileria still occur, particularly in cattle and African buffalo (Syncerus caffer). One such infection is Corridor disease caused by T. parva lawrencei, which is controlled by restricting the movement of African buffalo. Other species reviewed are T. parva bov...
