Abstract

Surveys of human intestinal protozoa in the United States have been confined mostly to Eastern sections of the country and to the Pacific coast. There has been little work done concerning these parasites in western mountain states, and no previous surveys have been made of these organisms in the Intermountain West.

It is important that the kinds and numbers of these parasitic protozoa be determined for this locality; and it is only through surveys that the harmful, as well as the commensal, intestinal protozoa can be determined and treated.

In 1933, the city of Chicago experienced a general epidemic of amoebic dysentery, believed to be caused by a Endameba histolytica carrier. The seriousness of this epidemic led to the realization that the amoebic dysentery of the tropics could occur in temperate regions. It is one of the purposes of surveys to recognized the incidence of pathogenic protozoa, with the purpose of averting possible epidemics of dysentary, diarrhea and other minor intestinal disturbances.
