Role of Gut Microbiota in Human Health

Over the last 15 years, microbiome has attracted the attention of medical scientist and microbiologists. Human gastro intestinal tract harbors a complex and dynamic population of microorganism which exerts influence on the host during homeostasis and diseases. Establishment of human gut microbiota during infancy depends on multiple factors. One of the main drives in shaping the gut microbiota across the lifetime is the quality of diet. Gut bacteria play a crucial role in maintaining the immunity and metabolic homeostasis and help in protection against various enteric pathogens. Advancement in computational biology and DNA sequence technology has revolutionized the quality research in the field of microbiome. Alteration in microbiome is associated with disease including inflammatory bowel disease, cardiovascular disease, asthma, obesity, metabolic syndrome and immune mediated conditions.
