ABSTRACT

For years I have longed to have the medical profession observe the human intestinal protozoa as plainly as I have seen them.

On account of the immensity of the subject this film is limited to those protozoa of major importance to medicine today; viz., Endameba dysenteriae (histolytica) and E. coli.
