Abstract

An organic load of 5%-10% fetal calf serum significantly reduced hypochlorite and UV radiation killing of Clostridium difficile spores, but organic material collected from hospital surfaces did not affect hypochlorite and only modestly affected UV killing of spores. Hypochlorite reduced aerobic microorganisms on unclean surfaces with no wiping.

摘要

5%-10%的胎牛血清的有机负荷显著降低了次氯酸盐和紫外线辐射对艰难梭菌孢子的杀灭作用，但从医院表面收集的有机物质不会影响次氯酸盐，并且只会适度影响孢子的紫外线杀灭作用。次氯酸盐在不擦拭的情况下减少了不洁表面上的需氧微生物。
