Variation in gut microbiota density in gut-colonized mice. Total fecal DNA levels per mg wet weight of feces. Ordinary one-way ANOVA was performed for comparisons between the samples. ^ap < 0.0001 versus Conventional, ^bp < 0.0001 versus Germ-free, ^cp < 0.0001 versus Env MT, ^dp < 0.05 versus Env MT and ^ep < 0.0001 versus Mouse FMT.
