Results of Certain Studies on the Stomach in Schistosomiasis Japonica

Until the opportunity to study American soldiers with Schistosoma japonicum infections presented itself during World War II, there was little doubt or inquiry into the generally accepted belief that the mature Schistosoma japonicum largely inhabit the radicles of the superior mesenteric vein, draining the small intestine. This concept was based on the careful and critical animal experimentations of Faust and Meleney (1), and the assumption that the worms choose similar sites in the human host was propagated because of the lack of accessible reports to the contrary on human autopsy material.

Although postmortem studies on soldiers infected in the southwest Pacific have not yet been published, some investigations have been reported which shed light on the probable distribution of adult S. japonicum in the human lower splanchnic area, and which have necessitated some revision of previous ideas on the subject.
