The significance of studying the role of microbes in health is increasingly recognized as these tiny organisms play critical roles in human physiology and disease processes. Microbes, including bacteria, fungi, and viruses, are essential for digestion, nutrient absorption, and maintaining a balanced microbiome that supports the immune system. Disruptions in microbial communities can lead to health issues such as gastrointestinal disorders and autoimmune diseases. Research into these microorganisms can inform treatments, promote health, and enhance our understanding of the relationship between humans and their microbial counterparts.
