The primary focus of microbiome research is to understand the diverse communities of microorganisms that inhabit various environments, particularly the human gut. This field explores the complex interactions between bacteria, viruses, and fungi, and their impact on human health, disease, and overall well-being. Microbiomes influence metabolism, immune response, and even behavior. Insights from microbiome studies can lead to innovative therapies, improved understanding of diseases, and the development of probiotics or dietary interventions to restore gut health, emphasizing the intricate link between microorganisms and human physiology.
