Amongst one such is, extreme environmental condition like High Altitude (HA) - very unique, difficult and full of health risk. Visiting population such as mountaineers, bikers, visitors, pilgrims, soldiers and special task forces who reaches High Altitude are at higher risks than at low landers. However, the reason how the extreme environment, stress, oxygen saturation and diet alter the oral & gut microbiota and affect its composition remains unclear. In this study we investigated the influence of High Altitude and stay at different heights, on the health of Indian population by using metagenomic approach to determine the variation in the gut microbiota. Fecal samples were collected from individuals, at four different time points viz. before the start of the ascending, after reaching 13000ft, descending at 11000ft and at the 16000ft –19000ft. Samples were analysed for whole genome sequencing. The oral & gut microbial diversity of members was significantly altered with the abundance of several bacteria, during the days of staying at 13000ft, 11000ft and 16000ft –19000ft. The oral & gut microbiota comprised mainly of the phyla Firmicutes, Proteobacteria, Bacteroidetes Euryachaeota, Actinobacteria and Unclassified at three time points. Further, the differential analysis of microbes across all the phyla and genus at all the four time points. Most of the identified microbial sequences were unclassified microbiota. Evidently, some metabolic pathways like amino acid, lipid and carbohydrate metabolism pathways were also altered.",

For microbiota analysis of the oral cavity and the gut, all provided stool and oral swab samples underwent 16S rDNA sequencing and subsequent bioinformatic analyses. Clinical outcome and MRI results were registered. Results: Compared to healthy controls, MS patients showed decreased alpha-diversity, significantly increased detection of Bacteroidetes and lower abundance of butyrate-producing members of the Firmicutes in their stool. Oral microbiota-patterns also had a reduced alpha-diversity yet showed unique and differential microbiota changes compared to stool such as increased levels of Proteobacteria and decreased abundance of Actinobacteria. Remarkably, following initiation of B-cell depletion, we observed increased alpha-diversity in the gut and the oral cavity as well as a long-term sustained reduction of pro-inflammatory Gram-negative bacteria (e.g., Escherichia/Shigella).Conclusion: MS patients have altered stool and oral microbiota diversity patterns compared to healthy controls, which are most pronounced in patients with higher disease activity and disability. Therapeutic B-cell depletion is associated with persisting regression of these changes. Whether these microbial changes are unspecific side-effects of B-cell depletion or indirectly modulate multiple sclerosis disease activity and progression is currently unknown and necessitates further investigations.",
