Abstract
Schistosomiasis ranks high on the list of diseases affecting large numbers of people throughout the world. With the increase of transoceanic travel and the discovery of new reservoir hosts, the problem has become more complex. Investigation and experimentation have increased correspondingly. Schistosomatium douthitti (Cort), non-pathogenic for man, but with a life cycle similar to forms parasitizing man, has been the subject of wide study within the last ten years.
Although invertebrates from Protozoa to Arthropoda have been exposed to X-irradiation, parasitic forms have been used in very few instances. Rabbits and dogs infected with Schistosoma japonicum (Katsurada) were X-rayed by Kawamura et al. (1924). Ascaridia galli (Schrank), Trichina and Rhabditis have been irradiated (Babero, 1952; Gould et al., 1953; Thomas and Quastler, 1949).
The present study was undertaken to determine what effect X-irradiation would have upon the life cycle of this digenetic trematode in the laboratory, and to compare the sensitivity of eggs with that of cercari ae to varying dosages of X-rays [TRUNCATED]
