Marchin explains that antibacterials use a variety of chemical compounds that destroy bacteria in different ways. Typically, bacteria don't develop a resistance to these compounds like they do to antibiotics. The QUATs slowly rupture the bacterial envelope, or cell membrane. Alcohol products dry bacteria up and the iodine compounds use oxidation to modify and destroy crucial proteins. Though these organisms have always lived with humans, certain advertisements might be making bacteria out to be more menacing than they really are.
Bacteria can be harmful to humans through outbreaks such as meningitis, pink eye, or food poisoning.
According to Marchin, it's not realistic to prevent all bacteria from entering or living on us. Despite the public image of germs, this does not have to be a disgusting or frightening idea. It is good to have a normal variety of bacteria to prevent other harmful bacteria from getting into your system. We have common bacteria on our skin, under our eyelids, in our throats. To keep the harmful bacteria away, Marchin says that washing hands is the best solution, which doesn't necessarily mean using a special product.
