Can a person become allergic to any of the natural bacteria colonizing his skin, nose, or bowels, so that he has permanent allergy symptoms?

In brief: No

Natural bacteria are just that' natural' they coexist with body.
When immunity( bodys fighting ability)is down they can cause infections. Allergies are seasonal or due to exposure to " allergens" in the environment and sometimes food.Gut natural bacteria can cause diarrhea in some people after antibiotic use.
