Theileria sergenti proliferates in SCID mice with bovine erythrocyte transfusion.
The unavailability of in vitro or in vivo experimental systems has been the major factor hampering the progress of research studies on Theileria sergenti, causative agent of theileriosis, a major disease of cattle in Japan. We report the first successful propagation of T. sergenti in SCID mice into which uninfected bovine erythrocytes (Bo-RBC) were supplied periodically. The infectivity of T. sergenti proliferated in an SCID mouse was ascertained by successful transfer of infection into another SCID mouse into which uninfected Bo-RBC were supplied periodically.
