From: Metaproteomic profiling of fungal gut colonization in gnotobiotic mice
Description of a gnotobiotic colonisation model by label-free quantitative metaproteomics. A Experimental design of shotgun label-free proteomic experiment, including enrichment of fecal microbial cells by differential centrifugation. B Detected fecal metaproteome composed of proteins originating from 12 bacterial, 5 fungal species, and mouse. C PCA score plot based on the relative levels of 3845 proteins quantified for mouse, bacteria, and fungi/yeast. X- and Y-axis show the first and second principal components, accounting for 53.1% and 12.2% of the total variation, respectively. Abbreviations of the mice treatment groups: B, bacteria; BY, bacteria-yeast; BY_ABX/AFX, bacteria-yeast and antibiotic or antifungal treatment; GF, germ-free; Y, fungi/yeast
