泰勒虫特异性小亚基（SSU）rRNA基因扩增证实了牛以及从密苏里州牛群中采集的美洲钝眼蜱和变异革蜱中存在微生物。索引动物的血液具有A型和D型泰勒虫SSU rRNA基因。D型基因也在两个队列牛的血液和蜱组织中发现。A型SSU rRNA基因先前从得克萨斯州和北卡罗来纳州的牛泰勒虫分离株中报道; D型基因从患有泰勒虫病的得克萨斯州奶牛中报道。
Theileria sp.-specific small subunit (SSU) rRNA gene amplification confirmed the presence of the organism in cattle and in Amblyomma americanum and Dermacentor variabilis ticks collected from a cattle herd in Missouri. Blood from the index animal had type A and type D Theileria SSU rRNA genes. The type D gene was also found in blood from two cohort cattle and tick tissues. The type A SSU rRNA gene was previously reported from bovine Theileria isolates from Texas and North Carolina; the type D gene was reported from a Texas cow with theileriosis.
