Nares-associated bacterial diversity in healthy and hospitalized adults¹.

1Table summarizes most abundant species/genera 0f 16S rRNA sequences in anterior nares swabs. See supplemental information for complete dataset. 2S. aureus non-colonized (Neg) with colonized (Pos) ICU patients, classified by culture and femA gene PCR. 3Inferred from highest bit-score in BLAST query. Blast %IDs <97 are named only to the genus level. Sequence abundances are listed for phyla (bold) and the 10 most abundant species/genera (italics; 90% of total sequences). 4p-value for Student's t-test comparison of colonized and non-colonized patients. Only values <0.1 are noted. 5Abundance of sequences for each category. Values are averages for subjects in a category. 6Number of sequences analyzed in each category. 7Subjects included in category. 8Specimens included in category. If more than one specimen/subject were analyzed, mean rRNA abundances were weighted by the number of specimens so that all subjects contribute equally to the mean value. 9Operational taxonomic units (OTUs) were assembled by complete-linkage clustering at a threshold of 99% uncorrected sequence identity. Tabulated values are means obtained through 1000 boot-strap replicates using rarefaction to normalize for differences in sampling efficiency. 10Schao1 non-parametric estimate of species richness for 99% OTUs.
