3. Fig 2
Sources of bacteria detected in mattress dust (MD) and floor dust (FD) samples in 4 individual homes (A-D). Bars show the proportional allocation of bacterial dust sequences to their probable sources of origin. Source categories and sequence affiliation criteria are defined in detail in the Methods.

4. Principal coordinate analysis (PCA) of 12 individual sequence libraries as computed via the UniFraq method (skin surface swab [S, rhombuses], mattress dust [M, rectangles], floor dust [F, triangles]; individual A [blue], B [dark red], C [green], and D [orange]). Axes in the diagrams represent the first 3 PCs (PC1, PC2, PC3), explaining 18.0%, 10.8%, and 9.4% variation in the data, respectively.
