An Observational, Cross-Sectional Study on Gut Microbiota: Comparison of the Indigenous Baiga Tribe and an Urban Indian Population.</p><p>The transition from traditional, subsistence-based lifestyles to modernized urban environments is a primary driver of the global decline in human gut microbiome diversity (the "disappearing microbiota hypothesis"). This dataset contains raw metagenomic sequencing data derived from fecal (stool) samples of 50 adult volunteers from Madhya Pradesh, India, designed to evaluate the impact of urbanization, diet, and lifestyle on human gut ecology.</p><p>The study cohort comprises two distinct populations: 25 individuals from the indigenous Baiga tribe (a Particularly Vulnerable Tribal Group located in Khatiya Narangi) who maintain a traditional, high-fiber foraging and farming lifestyle, and 25 individuals from a geographically shared, highly modernized urban population in Bhopal. The primary objective of this cross-sectional study is to identify structural, taxonomic, and functional shifts in the gut microbiome driven by market integration, refined diets, and environmental exposures. These sequences provide critical insights into the ancestral state of the human gut ecosystem, capturing unique fiber-degrading microbial networks, and document the profound ecological restructuring associated with urbanization and metabolic disease risk.
