ABSTRACT
Ayurveda is one of the ancient systems of medicine which is widely practised as a personalized scientific approach towardsthe general wellness. Ayurvedic prakriti is broadly defined as the phenotypes which are determined on the basis of physical,psychological and physiological traits irrespective of their social, ethnic, dietary and geographical stature. Prakriti is theconstitution of a person, which comprises vata, pitta, and kapha and is a key determinant of how one individual is differentfrom the other. Human microbiome is considered the ‘latest discovered’ human organ and microbiome research reiteratesthe fundamental principles of Ayurveda for creating a healthy gut environment by maintaining the individual-specificmicrobiome. Hence, it is important to understand the association of human microbiome with the Ayurvedic prakriti of anindividual. Here, we provide a comprehensive analysis of human microbiome from the gut, oral and skin samples of healthyindividuals (n=18) by 16S rRNA gene-based metagenomics using standard QIIME pipeline. In the three different prakritisamples differential abundance of Bacteroides, Desulfovibrio, Parabacteroides, Slackia, and Succinivibrio was observed inthe gut microbiome. Analysis also revealed prakriti-specific presence of Mogibacterium, Propionibacterium, Pyramidobacter, Rhodococcus in the kapha prakriti individuals Planomicrobium, Hyphomicrobium, Novosphingobium in the pittaprakriti individuals and Carnobacterium, Robiginitalea, Cetobacterium, Psychrobacter in the vata prakriti individuals.Similarly, the oral and skin microbiome also revealed presence of prakriti-specific differential abundance of diversebacterial genera. Prakriti-specific presence of bacterial taxa was recorded and only 42% microbiome in the oral samples and52% microbiome in the skin samples were shared. Bacteria known for preventing gut inflammation by digesting theresistant starch were abundant in the pitta prakriti individuals, who are more prone to develop gut-inflammation-relateddisorders. In summary, human gut, oral and skin microbiome showed presence
