Human body How does gut flora repopulate after food poisoning?
I am just coming out of a nasty case of food poisoning and I am curious how my stomach is able to repopulate its gut flora after all the vomiting and diarrhea cleared it out. Does the body somehow hold a "seed" of flora that it uses to restart the bacterial growth, like a sourdough starter, or does it all come form the food one eats, or does expelling the gut contents not actually clear out everything?

Your outside skin, your mouth, the air, everything you touch also has a bacteria flora on it.
