The pathogenicity of Theileria recondita infection in both splenectomised and non-splenectomised sheep was investigated. Following transmission of T. recondita to splenectomised animals both by adult ticks and blood transfusion a fever and severe macrocytic hypochromic anaemia developed which lasted the 9 days or more of patent infection. The prepatent period following tick attachment was about 8 days, but was variable following blood transfusion. Infection of normal animals caused a transient macrocytic hypochromic anaemia and slight fever which lasted throughout the period of low parasitaemia (7 days). The increase in mean cell volume was due to an increase in numbers of juvenile red cells in the peripheral blood. There was a transient neutrophilia and lymphocytopenia but no significant changes in thrombocyte or leucocyte numbers.
研究了绵羊泰勒虫（Theileria recondita）感染在脾切除和未脾切除绵羊中的致病性。通过成年蜱和输血将绵羊泰勒虫传播给脾切除动物后，出现了发热和严重的大细胞低色素性贫血，这种情况在显性感染的9天或更长时间内持续存在。蜱附着后的潜伏期约为8天，但输血后的潜伏期则有所不同。正常动物感染会导致短暂的大细胞低色素性贫血和轻微发热，在低虫血症期（7天）持续存在。平均细胞体积的增加是由于外周血中幼稚红细胞数量的增加。有短暂的中性粒细胞增多和淋巴细胞减少，但血小板或白细胞数量没有显著变化。
