I use to be really particular about stuff until I became more responsible. Bacteria is bacteria and it is all over the place. The bathroom is the least of your worries. Urine is fairly sterile until bacteria in the environment gets in it. In most cases we all have the same bacteria in our digestive tracks. The biggest problem people use to have was with parasites: round worms, tape worms and other creepy crawlers. Trust me, I'd rather come in contact with E coli than the flu. You can't avoid germs unless you spend your life inside a bubble. Growing up my parents had me so afraid of feces, decay, mold, and dirt. From a science point of view, they were over reacting. Follow a baby around for awhile and see what they put in their mouths.
