The study was carried out to determine the prevalence and associated risk factors of theileriosis in goats of Chattogram district, Bangladesh. Molecular characterization of circulating Theileria in this area was also undertaken. A total of 400 samples were collected from goats of different breeds, ages and sex with relevant information of rearing and management. The prevalence of theileriosis was 8.50% (34/400) by polymerase chain reaction though all of those samples were test-negative by microscopic examination. Among different risk factors season, breed and tick infestation were found to be significantly (p ≤ 0.05) associated with the prevalence of theileriosis in goats. Serous nasal discharge and swollen lymph nodes were determined to be significant clinical signs. The Theileria spp. detected in the present study closely resemble isolates which were previously detected in Myanmar and China. Further large scale epidemiological studies are required to identify the circulating species and responsible vectors, which would facilitate control measures for this disease in Bangladesh.
本研究旨在确定孟加拉国 Chattogram 地区山羊泰勒虫病的流行情况和相关风险因素。还对该地区循环中的泰勒虫进行了分子特征分析。共采集了 400 份来自不同品种、年龄和性别的山羊样本，并收集了饲养和管理的相关信息。聚合酶链反应检测到的泰勒虫病流行率为 8.50%（34/400），尽管所有这些样本的显微镜检查均为阴性。在不同的风险因素中，季节、品种和蜱虫感染与山羊泰勒虫病的流行呈显著相关（p≤0.05）。浆液性鼻漏和淋巴结肿胀被确定为显著的临床症状。本研究中检测到的泰勒虫属与之前在缅甸和中国检测到的分离株非常相似。需要进一步开展大规模的流行病学研究，以确定循环种和责任载体，这将有助于在孟加拉国控制这种疾病。
