Outline of Final Research Achievements	The purpose of this study was to determine the conditions of fine bubbles suitable for cleaning and disinfecting medical equipment and the hands of medical personnel. As a result, (1) the sterilization or growth inhibition effects of control (air-dissolved water), air-fine bubble water, ozone-fine bubble water, and ozone-dissolved water on E. coli were verified, suggesting that ozone-fine bubble water has cleaning and sterilization effects. The results indicated that ozone-fine bubble water had a bactericidal effect on hand hygiene. (3) Experiments on the germicidal effect of ozone fine bubble on indigenous bacteria on hands were conducted with the aim of introducing it into hand hygiene, and it was suggested that there was a reduction effect on indigenous bacteria on hands.
