Abstract
Samples of cutaneous flora were obtained from the antecubital fossa of 20 healthy volunteers before and after treatment with hydro-alcoholic solutions of chlorhexidine (CHX) and of hexamidine (HXM). Percentage reductions in bacterial flora were statistically greater (p <0.001) after CHX (99 to 100%) than after HXM (about 70 to 90%). Furthermore, CHX had a smaller disturbing effect upon the natural balance of the bacterial population than HXM with a more rapid return towards the initial proportions of the different organisms one hr after treatment.
