Comparison of the mucosa-associated microbiota between the ulcerated and nonulcerated ileum.

<p>(A) Molecular fingerprinting of the mucosal bacterial communities. U indicates the ulcerated ileal mucosa and NU is the nonulcerated ileal specimen. (B) Hierarchical distance clustering of mucosal DGGE profiles from CD patients. The similarities between mucosal specimens are shown in the dendrogram.
