Gut microbiota refers to the diverse community of microorganisms, including bacteria, viruses, fungi, and archaea that reside in the gastrointestinal tract of humans and animals. These microorganisms play a crucial role in various physiological functions, such as digestion, immune regulation, nutrient absorption, and metabolism. Research in this area focuses on understanding the composition, diversity, and function of the gut microbiota, as well as its impact on health and disease. Studies have shown that imbalances in the gut microbiota, known as dysbiosis, have been linked to a variety of conditions, including obesity, inflammatory bowel disease, allergies, and even mental health disorders. Understanding the role of the gut microbiota in health and disease is an active area of research with promising implications for personalized medicine and therapeutic interventions.
