Japanese Theileriosis, caused by hemoparasite Theileria orientalis sergenti, is one of the most serious diseases in Japan. As the pathogenicity is not strong, T. orientalis sergenti is a benign Theileria. The disease is found mainly in grazing cattle, and infected calves show anemia and growth retardation. Additionally, drug treatment is costly and labor-consuming. It has been required the genetic improvement of resistance to Japanese Theileriosis (Minami, 1989). The objects of our study are : 1) to discuss the feasibility of genetic improvement in disease resistance to Japanese Theileriosis and 2) to discuss the use of plasma lipid components information as physiological indicators for genetic improvement of disease resistance to Japanese Theileriosis.
