Figure 1: Genus composition and dispersion of 60 sequencing samples.

From: Alterations in Gastric Microbiota After H. Pylori Eradication and in Different Histological Stages of Gastric Carcinogenesis

Figure 1

(a) The relative abundance distribution of major genera across 60 sequencing samples. Only genera with relative abundance > 0.5% were shown, and the others were grouped into “Other” item. Genera were sorted by the decreasing order of average relative abundance. Samples were ordered according to their histological information. Samples with the same prefix were from the same individual. For IM samples, 1 indicates antral biopsy sample while 2 is corpus biopsy sample. For cancer samples, 1 indicates adjacent tissue biopsy sample while 2 is tumor biopsy sample. The “E” suffix represents samples after HP eradication. (b) The Veen plot of common OTUs among different group of samples. The number indicates the number of shared OTUs. (c) Principle coordinate analysis (PCoA) based on OTUs relative abundance profile. The variance explained by PC1 and PC2 are 55.3% and 13.3%, respectively. The distance was measured by root Jessen-Shannon divergence (rJSD). Points represent samples, and the color indicates group information. The accompany dendrogram was given in Supplementary Figure 5.
