Differential bacterial genes in male athletes after race and probiotic supplementation.

Male	C vs R	Total: 146	Male	C vs P	Total: 145
Firmicutes	2		Firmicutes	7
Bacteroidetes	2		Bacteroidetes	2
Proteobacteria	4	Diff: 19	Proteobacteria	2	Diff: 19
Actinobacteria	8		Actinobacteria	5
Others	3		Others	3

Note: ‘C vs R’ or ‘C vs P’ represents the change in microbiota after race or probiotic supplementation, respectively; ‘Total’ means the number of genus detected in total, and ‘Diff’ means the number of differences in significant genus.
