东方泰勒虫（Theileria orientalis）是一种良性的牛源寄生原虫，偶尔会给畜牧业造成严重的经济损失。我们报告了T.在越南Thua Thien Hue省的94头越南黄牛、43头水牛、21只绵羊、21只山羊和85头牛的吸血蜱中发现东方蜱。将T.用聚合酶链反应从13头牛（13.8%）、11头水牛（25.6%）、1只绵羊（4.8%）和9只蜱（10.6%）中检出东方蜱。利用MPSP基因序列的系统发育分析表明，存在7种基因型，4种先前分类的基因型（1型、3型、5型和7型）和3种新的基因型（N-1型、N-2型和N-3型）。
Theileria orientalis is a benign bovine protozoan parasite that occasionally causes serious economic loss in the livestock industry. We report the findings of a molecular epidemiological survey of T. orientalis in 94 Vietnamese yellow cattle, 43 water buffaloes, 21 sheep, 21 goats and 85 blood-sucking ticks of cattle in the Thua Thien Hue province of Vietnam. The major piroplasm surface protein (MPSP) gene of T. orientalis was detected using polymerase chain reaction from 13 cattle (13.8%), 11 water buffaloes (25.6%), 1 sheep (4.8%) and 9 ticks (10.6%). Phylogenetic analysis using MPSP gene sequences showed the presence of seven genotypes, four previously categorized genotypes (Types 1, 3, 5 and 7) and three new genotypes (Types N-1, N-2 and N-3).
