Fig. 3From: Genome-resolved metaproteomic characterization of preterm infant gut microbiota development reveals species-specific metabolic shifts and variabilities during early lifeTaxonomic shifts in infants a 03, b 19, c 21, and d 23 based on protein abundance. Relative abundance of microbial community is based on assigning proteomic data to constructed metagenomes. Shannon diversity index is used to characterize species diversity (both abundance and evenness of the species present) and calculated from the relative abundance of proteins at the species levelBack to article page
