Abstract

We have investigated the capacity of irradiated larvae of each of six different isolates of Schistosoma mansoni to protect mice against challenge infections from the homologous or a different isolate. The isolates differed in respect of their geographic origins, and in the lengths of time they had been maintained in the laboratory. All isolates induced significant protection against unattenuated challenge infections, and neither the degree of geographic disimilarity between vaccinating and challenge parasites, nor the numbers of laboratory cycles, appeared to influence the degree of protection induced by irradiation-attenuated larvae.
