What Is the Role of Commensal Microorganisms in the Body?
Commensal microorganisms play several crucial roles in maintaining homeostasis and overall health. They help in the digestion of food, synthesis of vitamins, development of the immune system, and protection against pathogenic microorganisms. For example, in the gastrointestinal tract, commensal bacteria such as Bacteroides and Lactobacillus aid in the breakdown of complex carbohydrates and the production of essential vitamins like K and B12.
