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.
