Bacterial operational taxonomic units (OTUs) derived from clone libraries
| Bacterial species* | n† | % |
|---|---|---|
| *Nomenclature according to Bergey’s Manual of Determinative Bacteriology (Holt, 1994). | ||
| †Full length 16S rDNA sequences from a total of 1019 clones from three biopsies of patients with ulcerative colitis, Crohn’s disease, and a normal control using all bacteria primer sets. Specific bacteria were identified by NCBI BLAST analysis using search results of at least 97% similarity (NCBI BLAST, http://www.ncbi.nlm.nih.gov/). | ||
