Composition of caecal intestinal microflora of mice in the AR and CO groups. OTUs
(operational taxonomic units), which correspond to either T-RFs (terminal restriction
fragments) or T-RF clusters, were detected by T-RFLP analysis. Values are means ± SE
(n = 7). **Significantly different (p<0.01) from the CO group. The data were
analyzed using t-test analysis. The letters correspond to the following phylogenetic
bacterial groups: (A) Bacteroides, Clostridium cluster IV (OTU 370);
(B) Clostridium cluster IV (OTUs 168, 749); (C)
Clostridium cluster IX, Megamonas (OTU 110); (D)
Clostridium cluster XI (OTU 338); (E) Clostridium
subcluster XIVa (OTUs 106, 494, 505, 517, 754, 955, 990); (F)
Clostridium cluster XI, Clostridium subcluster
XIVa (OTU 919); (G) Clostridium subcluster XIVa,
Enterobacteriales (OTU 940); H: Clostridium
cluster XVIII (OTUs 423, 650); (I) Bacteroides (OTUs 469, 853); (J)
Bifidobacterium (OTU124); (K) Lactobacillales
(OTUs 332, 520, 657); (L) Prevotella (OTUs 137, 317); (M) Others.
