In South Asia, Theileria annulata is known to be less pathogenic to local breeds of Bos indicus cattle comparing to Bos taurus cattle and some of mix breeds between them. Seroepidemiological surveys have revealed high sero-prevalence of T. annulata in asymptomatic local breeds of cattle in Bangladesh. Therefore, these asymptomatic infection in local breeds can be infectious sources to more sensitive breeds. In this study, 59 bloods of cattle showing no symptom were screened by species specific PCRs for hemoto-protozoan parasites, to prove the existence of T. annulata parasite in asymptomatic cattle in Bangladesh. The T. annulata infection was confirmed along with other parasitic species, and this is the first report of T. annulata DNA detection in Bangladesh.
在南亚，已知环形泰勒虫对本地瘤牛品种的致病性低于对普通牛品种以及它们之间的一些杂交品种。血清流行病学调查显示，孟加拉国无症状本地牛品种中环形泰勒虫的血清阳性率很高。因此，这些本地品种中的无症状感染可能是更敏感品种的传染源。在本研究中，通过针对血液原虫寄生虫的种特异性聚合酶链反应（PCR）对59头无症状牛的血液进行了筛查，以证实孟加拉国无症状牛中存在环形泰勒虫寄生虫。除其他寄生虫种类外，还确认了环形泰勒虫感染，这是孟加拉国首次报道检测到环形泰勒虫DNA。
