从苏丹的两个地方收集了安纳托利璃眼蜱：苏丹北方的Eddamer和苏丹中部的Wad-Medani。允许它们蜕皮为成年蜱，使用Feulgen染色评估其唾液腺中的泰勒虫感染。在Eddamer，检查的123只蜱中有49.6%感染泰勒虫，平均感染强度为1.3（即感染腺泡数/感染蜱数）。在Wad-Medani，162只蜱中有8.6%被感染，平均感染强度为7.9。在这两个地方，感染率在女性比男性蜱。当成年H. a. anatolicum应用于两只易感小牛，两只动物都发展为严重形式的泰勒虫病。
Hyalomma anatolicum anatolicum nymphs were collected from two localities in the Sudan: Eddamer in Northern Sudan and Wad-Medani in Central Sudan. They were allowed to moult to adult ticks, which were assessed for Theileria infection in their salivary glands using Feulgen stain. At Eddamer, 49.6% of 123 ticks examined were infected with Theileria and the mean intensity of infection was 1.3 (i.e. the number of infected acini/number of infected ticks). At Wad-Medani, 8.6% of 162 ticks were infected and the mean intensity of infection was 7.9. The prevalence of infection was higher in female than in male ticks at both localities. When adult H. a. anatolicum were applied onto two susceptible calves, both animals developed the severe form of theileriosis.
