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.
