Abstract
We investigated the acidic and alkaline electrolyzed waters generated in an approved automatic endoscope-washing and -disinfecting apparatus for their eliminating effect on the ceramic cylinder and endoscope which were contaminated with in vitro with mycobacteria, Helicobacter pylori and bovine viral diarrhea virus as an alternative of hepatitis C virus. It turned out that washing with the acidic electrolyzed water (pH2.5; 30ppm available chlorine) following the alkaline electrolyzed water (pH11.0) was effective for the elimination of the contaminated bacterial species and virus. The results suggested the approved endoscope-washing and -disinfecting apparatus should work well in its clinical use.
