Description:Principal coordinate analysis depicting the different sample types. Rectal swabs, fecal samples and mucosal biopsies may sometimes be very similar, but on a whole, these three sample types seem to harbor more or less distinct microbiota. Profiles are similar to those of fecal samples in unprepped patients, especially for the phylum Bacteroidetes. We suggest that rectal swabs may be ideally suited for large-scale studies and for routine clinical applications of microbiota profiling. Whereas correlation of swab profiles to fecal profiles was quite high in patients who did not undergo extensive intestinal preparation for colonoscopy, the similarity between different sample types was markedly lower in the colonoscopy group.
