Major depressive disorder (MDD) is among the most prevalent mental disorders worldwide. Factors causing pathogenesis of MDD include gut microbiota (GM), which interacts with host through gut-brain axis. In previous studies GM in patients, 16S rRNA sequencing was used, provided information about composition but not function. our study, we analyzed whole metagenome data to assess changes both and functional profile GM. We looked at 36 compared that 38 healthy volunteers. Comparative taxonomic...
