Excerpt from A Survey of the Intestinal Entozoa, Both Protozoal and Helminthic, Observed Among Natives in Johannesburg, From June to November, 1917

In a tropical or sub-tropical country, where there is a large resident, yet uctuating, native population, as well as a European community, it is desirable to have definite information as to what intestinal animal parasites are present among the coloured races, and the possibilities of sporadic or epidemic diseases of entozoal origin that may arise among these people.

During the six months June to November, 1917, I was engaged in a systematic examination of the stools of male Natives in hospital in Johannesburg, whether for surgical or medical reasons, suffering chie y from other than intestinal complaints, while the stools of a smaller number of similarly circumstanced white men were examined for Entozoa. A small number of dysenteric stools were also examined, which may be considered as representative of those cases of dysentery which normally occur among the indigenous population under non-war conditions. A detailed examination of the protozoal and helminthic contents of the intestines of over 100 Natives examined post mortem was also made. The work enables a preliminary statement to be made as to the nature and distribution of the animal parasites among the Natives. It further sheds some light on the existence of a very limited protozoal fauna that may, perhaps, be considered normal to the human intestine, although exceedingly limited in extent as compared with the abundant bacterial ora that is usually present. Definite inform ation as to the action and effects of certain parasitic Protozoa upon the human intestine has also been obtained.

The results, while not indicating the presence of parasites causing diseases of marked economic importance, yet clearly indicate that certain Protozoa do occur, e.g., Giardia (lamblia) intestinalis, which, under circumstances causing general lowered vitality among many Natives, would multiply rapidly, and produce intestinal diseases, such as diarrhoea, in epidemic form. Several comments regarding such Entozoa will be found in the paper.
