A Preliminary Study of Biliary Microbiota in Patients with Bile Duct Stones or Distal Cholangiocarcinoma

Figure 2

Relative taxa abundance and OTUs comparison in patients with dCCA and the onset of common bile duct stones. The overall microbial composition at the phylum (a) and genus (b) level illustrated that the taxonomic composition varies widely among individuals, but Proteobacteria and Firmicutes were the dominant phylum among all individual, and Escherichia/Shigella and Halomonas were the major genus. It indicated that the core OTUs from patients with dCCA and the new onset of common bile duct stones were composed of 536 and 703 OTUs, respectively, of which 490 were shared between the two groups (c). The dCCA group (Tumor group, T) and the new onset of CBD stones group (CBD stones group, C) denoted as “Group T” and “Group C”, respectively, in the figure.
