Metagenomic Data Utilization and Analysis (MEDUSA) and Construction of a Global Gut Microbial Gene Catalogue

Taxonomic analysis of the gut metagenome.
(a) Genus abundance of each sample ordered by increasing Bacteroides relative abundance. There is a continuous gradient of increasing Bacteroides relative abundance in the studied samples. The 20 most abundant genera are shown, whereas the rest of the annotated reads are grouped into other. (b) Boxplots showing the relative abundance of Bacteroides, Prevotella and Ruminococcus. The Prevotella abundance is low in most samples but a few samples have a major Prevotella abundance. (c) Shannon diversity index of the species abundance shows that Swedish and Metahit samples have a higher diversity compared to Chinese and American. (d) Pan and core species with a relative abundance above 10−4 in the subjects (repeated samples from the same subject excluded). The core percentage means that a species was present in at least % of the subjects.
