SELF-STERILIZING POWERS OF THE SKIN

Abstract
In a previous communication,1 it was shown that the ingestion of carbohydrates had a pronounced effect on the activity of micro-organisms on the skin. Because of this it was felt that the exhibition of agents which alter the blood sugar content might help toward rationalizing the observed relation between carbohydrate ingestion and the self-sterilizing process of the skin. A number of such substances were used, and, for comparison, other agents which do not alter the level of the blood sugar were also tried. METHOD The principle of the previous methods for determining the inactivation of organisms remained the same. In order to do away with certain apparent objections one new procedure was inaugurated. Previously an area was swabbed with a thin emulsion of organisms. At intervals of ten minutes, succeeding fourths of this area were swabbed with a cotton applicator moistened with distilled water. Then the organisms
