Hi Morgan,
I did a quick google search and found some interesting articles-

Of course, you must distinguish between "good" bacteria and "bad" bacteria..but I hope this helps

dear morgan,

The amount of bacteria vaires between different toilets and different mouths. You could do an experiment to determine this. You could take samples by swabbing toilet seats and mouths with different cotton swabs (sterile ones for the mouth). Then swab the samples into different agar petri dishes. Then incubate and count the number of bacterial colonies. If you want more information about the experiment post more posts. Also, if you do this experiment or another experiment be careful because working with bacteria could be dangerous. Take safety precautions like wearing gloves and placing the petri dishes away from food, people, pets, and other things.

good luck,
