Figure 3.
Venn diagram showing (A) the distribution of all 343 duodenum OTUs, calculated at 97% dissimilarity, identified in the 52,880 16S rDNA sequences. 13 OTUs were common to all 4 individuals. (B) The distribution of all 219 Jejunum OTUs identified in 61,139 sequences. 2 OTUs were common to the 4 individuals. (C) The distribution of all 438 ileum OTUs identified in 51,567 sequences. 14 OTUs were common to the 4 individuals. (D) The distribution of 129 OTUs common in all 4 individual in the different intestinal segments. Only 1 OUT was found in all 4 segments. The cecum data were obtained from Bennett et al.13 (D1–D4: duodenum of the 4 emus examined, J1–J4: jejunum, I1–I4: ileum, C1–C4: ceca).
