从蜱虫幼虫中分离出一种斯里兰卡牛巴氏杆菌菌株（指定为A菌株），并通过在20头切除脾脏的小牛中传代，然后辐照制备疫苗。用从澳大利亚引进的牛巴氏杆菌A株和疫苗株（命名为K株）对37头从澳大利亚南部进口的易感公牛进行了免疫。接种后3周，监测直肠温度、红细胞压积、寄生虫血症和明显的临床体征。结果表明，A株毒力略强于K株，但适合于有良好监督的牛的免疫。
A Sri Lankan strain of Babesia bovis (designated A strain) was isolated from larval ticks and prepared for use as vaccine by syringe-passage in 20 splenectomised calves followed by irradiation. The A strain and a vaccine strain of Babesia bovis (designated K strain) brought in frozen form from Australia were used to vaccinate 37 susceptible bulls imported from southern Australia. Rectal temperatures, packed cell volumes, parasitaemias and overt clinical signs were monitored for three weeks following vaccination. The results indicated that the A strain was slightly more virulent than the K strain but suitable for the vaccination of well-supervised cattle.
