life cycle if applicable) that commonly survive in chlorinated, potable municipal
water supplies
List 6 microorganisms (with the stage in their
life cycle if applicable) that commonly survive in chlorinated, & potable municipal
water supplies.
I was wondering if there's a way I can kill every germ (including "super-bugs") on my hand? And if so, how I can do it? And if not, why not? One microbiologist said I can kill every germ on my hand, by lathering my hands in soap, rinsing them with warm water, re-lathering them in soap, rinsing them with warm water again, wiping them dry, and then rubbing them vigorously with hand sanitizer. I was wondering, is that really true?
