摘  要：
采用PCR技术,从新疆焦虫病疫区感染牛的全血中扩增到Tams1基因,该基因长度为846 bp,编码281个氨基酸。同源性分析表明,该基因与其他9个国际流行虫株的核苷酸同源性为93.6%~99.8%,氨基酸同源性为88.6%~99.6%。系统发育进化树分析表明,新疆分离株同印度株、毛利塔尼亚株、土耳其株、北非共和国株进化途径一致,与苏丹株和巴林株进化途径相差较远。氨基酸抗原决定簇分析发现新疆分离株编码的氨基酸有13个抗原决定簇。

摘  要：
In order to analyze gene sequence of the bovine Theileria annulata in Xinjiang,a pair of primers was designed,Tams1 gene fragment was amplified by PCR,sequence of positive clones was showed that the gene fragment has a total length of 846 bp,which encoded 281 amine acids.The homology of the nucleotide sequence was 93.6%-99.8%,and homology of the Amino acid sequence was 88.6%-99.6% compared with other 9 international prevalent strains.The phylogenetic evolution tree was shown that the isolated Xinjiang strain is closely related to those from India,Mauritania,Turkey,Tunisia,but not as well to those from Bahrain and Sudan.The analysis of antigenic determinant was shown that there were 13 antigenic determinats in the encoded strains isolated from Xinjiang Tams1.
