The host antigen phenomenon in experimental murine schistosomiasis: The transfer of 3-week old Schistosoma mansoni between two inbred strains of mice

A surgical technique for the transfer of 3-week old Schistosoma mansoni to the mesenteric veins of mice is described. Parasites grown in a donor C3H/StCrl strain survive on transfer to recipient C57BL/10J mice despite prior immunization with C3H/StCrl cells or skin grafts. The findings indicate that the ‘species-specific’ mouse host antigens associated with adult worms in xenogeneic transfers do not have an allogeneic basis in these two strains.
