Abstract
Type-C rotavirus are propagated in swine testicular cells with reduced concentrations of proteolytic enzyme for subsequent production of antigen and antiserum for use in diagnostic kits and for killed vaccines to prevent Type C rotavirus infections. Propagation of Type C rotavirus in the ST cells can also lead to virus modification for subsequent use as a modified live virus vaccine to prevent Type C rotavirus infections.
