Relative abundance of bacterial phyla from mouse cecal contents after 28 days of oral gavage with 10 mg/kg bw/day of 110 nm PVP-coated AgNP in comparison to water and silver acetate. A. Mean % relative abundance of all phyla for mice from each group, with mean percentage of each phylum indicated. For all groups, Bacteroidetes was the major phylum present, followed by Firmicutes and the murine-specific phylum Deferribacteres. Other phyla (combined) were present at <4% in each group and consisted of unclassified phyla (most abundant, 1–2%), followed by Actinobacteria, Proteobacteria, Tenericutes, Verrucomicrobia, and TM7, each present at <1%. B. Median (horizontal bar), interquartile range (box) and minimum/maximum for major phyla in each group. There were no significant differences between groups with respect to microbial community composition and structure at the phylum level (ANOVA, p=0.861).
