Normal flora are the non-pathogenic microorganisms that live in and on our bodies in areas where they help maintain balance. By occupying niches on the skin, in the gut, and on mucous membranes, they prevent harmful microbes from taking hold (competitive exclusion). They also contribute to health by producing vitamins, aiding digestion, and helping train the immune system. They aren’t pathogens. While a non-pathogen describes harmless organisms, it doesn’t specify their resident, balancing role. A reservoir refers to places where pathogens persist, not to beneficial residents. So the term that best fits is normal flora.
