[Qualitative and quantitative analysis of the residual hand flora after hygienic-type washing with a soap and a foaming antiseptic solution].
Activity of a liquid soap and of a 4% povidone iodine detergent solution on hand skin flora after application for one minute ("hygienic type" handwashing) was studied. Samples were taken using a "bag" washing method. Total aerobic flora was determined quantitatively. Transient flora (Gram negative bacilli and mannitol positive Staphylococci) was determined both quantitatively and qualitatively. 54 determinations were performed (29 with liquid soap and 25 with povidone iodine) on 17 volunteers of the staff of the hospital bacteriology laboratory. After application of liquid soap, total flora, i.e. 10(6) bacteria per hand, was not reduced and the number of mannitol positive Staphylococci was increased. With povidone iodine, the reduction in total flora was 0.2-0.3 log 10 and the number of mannitol positive Staphylococci was decreased. With both products, Gram negative bacilli were eliminated in 60% of cases and greatly reduced in the remainder.
