Abstract

Summary

During a study of the occurrence and treatment of natural infections of in , another amoeba was encountered which produces only mononucleate cysts, but which possesses rod-shaped chromatoidal bodies and nuclear structures which may be similar to those of . Judged on the basis of morphology this amoeba appears to be identical with Prowazek 1912 of the domestic pig and with Swellengrebel 1914 of monkeys. An amoeba with similar morphological appearances has also been found in man.

often possesses a spherical or ovoidal inclusion mass in the encysted stage and this structure differentiates it from cysts of or of

appears to be a commensal in the domestic pig and in the monkey. When found in the monkey it does not respond to amebicidal therapy as readily as does .

The similarity of these amoebae as here reported is based only on morphological structure since there has been no opportunity to attempt reciprocal animal infection experiments.
