Transovarial transmission of a newly isolated large intraerythrocytic parasite, Babesia sp. 1 by Haemaphysalis longicornis was experimentally demonstrated. Larvae of H. longicornis were transovarially infected with the parasite by feeding as adults on the calf which had been experimentally infected with B. sp. 1. Piroplasms of B. sp. 1 were observed in peripheral blood of the calf which was infested with the parasite-infected larvae. Based on the transmissibility of the parasite with vector ticks, this parasite was suggested to be a variety of B. ovata. Thus, we propose a new variety name for B. sp. 1 as B. ovata oshimensis n. var.
实验证明了长角血蜱可经卵传递一种新分离的大型红细胞内寄生虫——巴贝斯虫1号种。长角血蜱的幼虫通过成虫吸食经实验感染了巴贝斯虫1号种的小牛血液而经卵感染该寄生虫。在感染了寄生虫的幼虫的小牛外周血中观察到了巴贝斯虫1号种的梨形虫。基于该寄生虫与媒介蜱的传播性，该寄生虫被认为是卵形巴贝斯虫的一个变种。因此，我们为巴贝斯虫1号种提出一个新的变种名称——卵形巴贝斯虫大岛变种。
