Fig. 2From: Effect of different sweeteners on the oral microbiota and immune system of Sprague Dawley ratsStatistical comparison of the relative abundance (a, b) and alpha diversities (c, d) of the oral microbiota observed in each of the four groups of rats. a Comparison of dominant phyla in the control (c group), xylose (x group), sucrose (s group), and saccharin (sa group) groups. b Comparison of the dominant genera in the control (c group), xylose (x group), sucrose (s group), and saccharin (sa group) groups. c Bacterial community richness in each of the four groups. d Bacterial community diversity in each of the four groups. p < 0.05 was considered significant. * 0.01 < p ≤ 0.05, ** 0.001 < p ≤ 0.01, *** p ≤ 0.001Back to article page
