What type of microorganisms can be beneficial?

Nonpathogenic bacteria are microorganisms that do not cause disease and can actually provide beneficial effects. These bacteria play essential roles in various environments, including the human body, where they contribute to digestion, synthesize vitamins, and help maintain a healthy balance of the microbiome. They can even be used in skincare and beauty treatments to promote healthy skin, as they can assist in the prevention of harmful infections by outcompeting pathogenic bacteria for resources.

In contrast, while other microorganisms such as fungi can have beneficial strains, not all fungi are inherently advantageous, and some can be harmful. Bacteria also include pathogenic strains that cause infections. Therefore, recognizing nonpathogenic bacteria specifically as beneficial helps underline their unique role in health and wellness without the ambiguity that comes with other categories of microorganisms.
