A fatal case of generalized amoebiasis due to a protozoon closely resembling, if not identical with, Iodamoeba bütschilii

Abstract

A Japanese soldier, aged 22, captured in New Guinea, later died of generalized amoebiasis. The only organism present was an amoeba apparently indistinguishable from I. butschlii. This amoeba was very abundant and occupied all the sites usually occupied by Endamoeba histolytica in such cases. If this organism is the true causative agent of the pathological conditions present, then it is the first authenticated example of tissue pathology due to what seems to be I. butschlii.
