That's what I thought as well. When I took a biology class in college we asked why hand sanitizer that kills 99.9 percent of germs is fine, but excessive use of antibiotics breeds super germs. The professor told us that it just destroys it at a molecular level, so there's nothing to resist, it'd be like trying to develop a resistance to being torn apart by a black hole.

- lima 8y agoIt's known that some bacteria can survive just fine in moderate concentrations (the paper points out lactic acid bacteria in sake, surviving at more than 18%) by means of membrane transporters. The authors suggest that insufficient concentrations could allow tolerant bacteria to survive. > As alcohol tolerance increases, we hypothesize that there will be skin surfaces in contact with alcohol-based hand rubs or inanimate surfaces in contact with other alcohol-based cleaning agents that do not receive the maximum biocide concentration or contact time required for effective bacterial killing.
