Conclusions
-
1.
The incidence of intestinal protozoal infection in all parts of the United States is such that each physician is confronted frequently by infected persons.
-
2.
The exact relationship of these parasites to the host is not yet proven.
-
3.
Proper statistical evaluation of protozoal infection and assay of the part played by a protozoon in the symptomatology of a patient depend on compensation for the fact that protozoa are not present daily in the stool of infected persons.
-
4.
Material may be rendered unfit for examination by improper collection or by giving the examinee oil, barium or bismuth.
