Fig. 3: Differences in gut microbiota bacterial composition.

a Violin plots presenting the abundances of Firmicutes, Bacteroidetes, and Proteobacteria in fecal samples obtained from the seven participants. P, participant. b Taxonomy tree of 58 genera identified in this study. Three bar charts from inside to outside show the total number of short-term blooms (Black bar chart), the number of short-term blooms in 7 participants (P1-P7) and the percentage of samples in which genus was detected in this study (Blue bar chart). The outermost red box plot shows the relative abundance of each genus in all samples. Boxplots display the distribution of data based on the five number summary: minimum, first quartile, median, third quartile, and maximum. General labeled in blue text are core genera identified in all samples. The background color represents the phylum. c Scores corresponding to the influence of nine factors (participant ID, date, workspace/office, drug use, yogurt consumption, fruit consumption, travelling abroad history, blood pressure, and blood sugar) on gut microbiota composition over time.
