Human Gut Microbiome contains collection of diverse species which help carry out various functions for the proper functioning of the human body. However, IBD is a condition where the diversity of this microbiome is significantly altered. Little is known about the causes and effects of these variations in the present literature. The next generation sequencing techniques provide suitable data for Metagenomic analysis leading to identification of uncluttered microorganisms, and make it possible to get detailed functional insights into the functional footprint of these altered microorganisms. This study uses of KEGG pathways for mapping functionality of the diverse gene sets in order to better understand function level changes caused due to the altered microbiome in case of IBD.
