PURPOSE:Babesia spp. and Theileria spp. are tick-borne pathogens of livestock globally. In this study, we investigated the presence and distribution of these pathogens in cattle from 20 locations in 4 Counties of Wuwei City. The aim of the present research was to evaluate the spread of piroplasms, so as to provide the epidemiological information for control piroplasmosis in the region.METHODS:The authors provided the molecular data for Babesia spp. and Theileria spp. and analyzed the obtained sequences of the 18S rRNA gene, Tams1 gene and MPSP gene by using the ClustalW program in MEGA version 6.06 software and BLASTn tool of NCBI GenBank database.RESULTS:The total infection rates were detected by nPCR with 1.8% for T. orientalis, 3% for T. sinensis, 0.6% for T. annulata, 1.8% for B. motasi and 0.6% for B. bigemina.CONCLUSIONS:To the best of our knowledge, this is the first report investigating T. sinensis from cattle by PCR in Wuwei City. In particular, ovine B. motasi has been for the first time detected in cattle in our study and its impact is worth discussing to figure out the potential reasons.

寄生虫病对养猪生产危害严重,一些寄生虫会引起猪急性发病甚至死亡.大部分寄生虫以夺取营养为主,导致猪出现消瘦、生长缓慢、生产效率低等问题.还有一些寄生虫病属于人畜共患病,对人类健康存在危害.本文将介绍民勤县乃至周边地区寄生虫对养猪业的影响以及防控措施,供养猪业者参考.
