title: Investigations on the sporicidal and fungicidal activity of disinfectants.
abstract: The sporicidal and fungicidal activity of disinfectants was studied in a suspension test. Glutaraldehyde 4%, sodium-dichloroisocyanurate-dihydrate (2400 ppm active chlorine) and peracetic acid 0.25% demonstrated after 30 min of exposure at 20 degrees C in the presence of 4% horse serum a clear activity against spores of Bacillus cereus. Under the same conditions formaldehyde 4% and glutaraldehyde 2% were also found to be sporicidal, but only after a longer time of exposure. Spores of Bacillus anthracis and B. cereus appeared to be comparably resistant against the investigated disinfectants, whereas conidiospores of Aspergillus fumigatus and Aspergillus niger were less resistant. Of the micro-organisms tested Candida albicans proved to be slightest resistant, while spores of Bacillus subtilis were found the most resistant.
