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.
