Re: Can H.pylori in mouth cause reinfection?

as long as you are sure that your h. pylori has been eradicated, it is very hard to get reinfected. of course, basic hygiene is required to reduce the chances of true reinfection. H. pylori will not survive outside human body. It's sensitive to oxygen and it's very slow growing. slow growing means, it cannot compete with other organism for nutrient. Therefore, it cannot survive on your tooth brush nor your yogurt. Not in soup, not in utensils, not in the air, not in water and not from soil. you may, in small chance, find h. pylori in toilet door handle, flush, and saliva. with a lot higher chance in someone else's vomit.
