Tabanids were collected in an area in northern Germany, where pastured cattle were abundant. Trypanosomatidae were identified in 14% of tabanids examined. Twelve cattle became infected with Trypanosoma theileri after applying usually 2-5 infected tabanids, to the intact oral mucosa. Haematopota pluvialis, Haematopota italica, Hybomitra micans and Tabanus bromius were identified as vectors. Infective stages of Trypanosoma theileri were identified in the gut and in the faeces of tabanids by transmission experiments. The minimum prepatent period was less than 4 days. No apparent signs of disease were observed in the infected cattle.
在德国北部一个放牧牛群密集的地区采集了虻类。在所检查的虻类中，14%被鉴定感染了锥虫科寄生虫。在完整的口腔黏膜上，通常让2至5只受感染的虻叮咬12头牛后，这些牛感染了泰勒锥虫。已确定雨大虻、意大利大虻、闪光角虻和厩螫蝇为传播媒介。通过传播实验，在虻的肠道和粪便中鉴定出了泰勒锥虫的感染阶段。最短潜伏期不到4天。在受感染的牛身上未观察到明显的疾病迹象。
