abstract
Theileriosis in cattle is a very important disease that causes economic loss through abortion and even death of the dairy cattle. Oriental theileriosis caused by Theileria orientalis is a disease newly reported from cattle of Assam, India. Two numbers of newly registered Lakhimi cattle breed from Assam were reported with high fever, swollen pre-scapular lymph nodes and mild anaemia. Laboratory diagnosis revealed presence of intraerythrocytic piroplasms of Theileria orientalis. Previously no published document was found regarding the occurrence of Theileria orientalis in Lakhimi cattle of Assam from the area of the present communication. Hence, this may be considered as the first report of Theileria orientalis in the Lakhimi cattle from Eastern Himalayan foothills bordering the states of Assam and Arunachal Pradesh.
