Piroplasmosis has been reported by the investigators in many area of the world. However, no detailed reports have been made on this disease in China. This project a comparison of Piroplasmosis in Japan with those other Theileria and Babesia species in China.Piroplasmosis in Japan except in the Okinawa Prefecture is caused by Theileria sergenti, Babesia ovata, and Babesia gibsoni, All three infectious agents are transmitted by tick species, Haemaphysalis longicornis. In china, ten species of piroplasmas that infect horse, cattle, buffalo, sheep and dog have been identified.B.bigemina mainly exists in the southern provinces. B.bovis is prevalent in Guizhou, Anhui, Shanxi and Henan provinces, and B.ovata in Guizhou, Hunan, Hebei, Henan and Jilin provinces.The epidemic areas of T.annulata are Neimeng, Xinjiang and the northern provinces. T.Sergenti is primarity distributed in Guizhou, Jilin, Liaoning, Hebei, Henan, Hunan, Yunnan, Shaanxi, Gansu and Ningxia provinces. B.gibsoni is the only identified piroplasmas infecting dog in China. It was initially found in Henan and Jiangsu provinces.From those results. We regard the following line :1. Investigation of comparative studies of piroplasma and vector ticks.2. Methods of artificial stimulation of resistance to vector ticks.3. Methods of immunization of cattle against disease.We blieve that further work to establish this is in progress.

梨形虫病在世界许多地区均有报道。然而，在中国，对这种疾病还没有详细的报道。本研究将日本梨形虫病与我国其他泰勒虫和巴贝虫病进行了比较，除冲绳县外，日本梨形虫病由瑟氏泰勒虫、卵形巴贝虫和吉氏巴贝虫引起，三种病原均由长角血蜱传播。在我国已发现10种梨形虫，主要感染马、牛、布法罗、羊和狗，其中二联B.bigemina主要分布在南方各省。牛B.bovis主要流行于贵州、安徽、山西、河南等省，卵形B.ovata主要流行于贵州、湖南、河北、河南、吉林等省，环毛癣菌主要流行于内蒙古、新疆和北方各省。长颈细颈蜱主要分布于贵州、吉林、辽宁、河北、河南、湖南、云南、陕西、甘肃、宁夏等省。吉氏B.gibsoni是我国唯一发现的感染犬的梨形虫。它最初是在河南和江苏省发现的。我们认为以下路线：1.梨形虫与媒介蜱的比较研究调查.人工刺激媒介蜱抗性的方法.牛的免疫方法。我们相信进一步的工作正在进行中。
