Abstract:
The successful transmission of Theileria ovis Rodhain, 1916 to splenectomized sheep by Rhipicephalus evertsi mimeticus Donitz and R. bursa Canestrini & Fanzago is recorded. The protozoon is acquired by the immature stages of these two ticks and transmitted by the ensuing adults. The course of the disease is accompanied by pyrexia and a transitory appearance of schizonts in films prepared from swollen lymph nodes while endoglobular parasites are demonstrable during the reaction and for long periods after recovery.
