Mongolians core gut microbiota and its correlation with seasonal dietary changes.

ABSTRACT: Historically, the Mongol Empire ranks among the world's largest contiguous empires, and the Mongolians developed their unique lifestyle and diet over thousands of years. In this study, the intestinal microbiota of Mongolians residing in Ulan Bator, TUW province and the Khentii pasturing area were studied using 454 pyrosequencing and q-PCR technology. We explored the impacts of lifestyle and seasonal dietary changes on the Mongolians' gut microbes. At the phylum level, the Mongolians's gut populations were marked by a dominance of Bacteroidetes (55.56%) and a low Firmicutes to Bacteroidetes ratio (0.71). Analysis based on the operational taxonomic unit (OTU) level revealed that the Mongolian core intestinal microbiota comprised the genera Prevotella, Bacteroides, Faecalibacterium, Ruminococ
