Alterations of Microorganisms in Tongue Coating of Gastric Precancerous Lesion Patients with a Damp Phlegm Pattern

Figure 4

(a) Column figure of differential microorganism of the GPL group compared with the healthy control group (E: GPL group, N: healthy control group). (b) Column figure of differential microorganism of the GPL damp phlegm pattern group compared with the GPL nondamp phlegm pattern group (C: GPL damp phlegm pattern group, D: GPL non-damp phlegm pattern group). The abscissa represented the species of microorganisms (showing the top 20 species with the lowest value), the ordinate represented the relative abundance of species, the columns with different colors represented each sample, and the “” on the column represented significant difference (). (a) The microorganisms named Solobacterium, Rothia, Oribacterium, and Alloprevotella with significant differences in the relative abundance between the GPL and healthy control groups at the genus level. Compared to healthy controls, the relative abundances of four microorganisms were significantly higher in the GPL group (). (b) The microorganisms named Terrisporobacter, Solobacterium, Porphyromonas, Parvimonas, Lactobacillus, Johnsonella, Gemella, Fusibacter, Azoarcus, and Acidothermus with significant differences in the relative abundance between the GPL damp phlegm pattern group and the GPL nondamp phlegm pattern group at the genus level. The relative abundances of ten microorganisms were significantly lower in the GPL damp phlegm pattern group compared to those in the GPL nondamp phlegm pattern group ().
