Hygienic hand disinfection tests in three laboratories.

摘要: A comparative study was made in three laboratories of a test for hygienic hand disinfection. Staphylococcus aureus applied to the fingertips total 74 volunteers (49 female and 25 male) effect washing with chlorhexidine preparations one non-medicated soap assessed after five applications. Fingertip inoculation is convenient realistic representation in-use situation. Although significant differences were obtained between log10 reductions organisms using same formulation different centres, periods centre, maximum single application preparation small, e.g. centres 0.39 centre 0.55, multiple applications difference 0.42 it 0.51. The similar all centres. This compares well other tests products can be placed rank order effectiveness. It concluded that this test, if carried out under controlled conditions described, sufficiently reproducible repeatable within used as standard test.
