Serological and morphological comparison of Theileria orientalis stocks from Australia, Britain, Iran, Japan and the USA with a more pathogenic stock from Korea, corresponding to T sergenti of Russian literature, showed that they all belong to one species, for which the name T orientalis is recommended. T orientalis is now known to occur on all continents. Macroschizonts and microschizonts, found in some of the calves infected with the Korean stock, are described and illustrated. Infections with the Korean stock were associated with early hyperthermia during the period schizonts are found, and commonly with high parasitaemias and anaemia even in unsplenectomised calves. The higher pathogenicity of this stock may be related to a faster rate of division. T orientalis may cause latent infection in sheep. With the exception of the stock from the USA, all stocks could be transstadially transmitted by Haemaphysalis longicornis and, or, H punctata.
对来自澳大利亚、英国、伊朗、日本和美国的东方泰勒虫毒株与来自韩国的一种致病性更强的毒株（相当于俄罗斯文献中的瑟氏泰勒虫）进行血清学和形态学比较，结果表明它们都属于同一个物种，建议将其命名为东方泰勒虫。现已知道东方泰勒虫在各大洲均有出现。文中描述并展示了在一些感染韩国毒株的犊牛体内发现的大裂殖体和小裂殖体。感染韩国毒株与裂殖体出现期间的早期发热有关，即使在未进行脾切除的犊牛中，通常也会出现高虫血症和贫血。该毒株较高的致病性可能与更快的分裂速度有关。东方泰勒虫可能会在绵羊中引起潜伏感染。除了来自美国的毒株外，所有毒株都可以经长角血蜱和/或微小牛蜱进行跨期传播。
