Abstract

Two Theileria parva stocks were isolated from control cattle during East Cost fever (ECF) field immunization trials at SAO Hill and West Kilimanjaro in the southern and northern parts of Tanzania respectively. Both parasite stocks caused severe clinical ECF which required antitheilerial treatment for 3 of the 5 experimentally infected cattle. Cattle recovering from infection with the two T. parva stocks did not develop a fever and only 1 of 4 animals developed scanty schizont parasitosis for one day during a challenge with T. parva (Kasoba) from northern Malawi. In contrast, both control cattle developed fever and schizonts, and one required antitheilerial treatment to survive.

摘要

在坦桑尼亚南部的圣山和北部的西乞力马扎罗进行东海岸热（ECF）现场免疫试验期间，分别从对照牛中分离出两株泰勒虫。这两种寄生虫株均引起严重的临床ECF，5头实验感染牛中有3头需要进行抗泰勒虫治疗。从这两株泰勒虫感染中恢复的牛没有发烧，在来自马拉维北部的泰勒虫（卡索巴）攻击期间，4头牛中只有1头在一天内出现少量裂殖体寄生虫血症。相比之下，两只对照牛都出现了发烧和裂殖体，其中一只需要进行抗泰勒虫治疗才能存活。
