Comparison of fecal microbiota among children in the ten cities.
(a) Alpha-diversities of fecal bacterial community in individual samples in each city. Individual phylotype-composition data were rarified using 2,000 reads per participant in two iterations. The number of observed OTUs, PD_whole_tree and Shannon Wiener index were calculated for each rarified OTU composition and averaged within the two iterations. The covariance of these calculated indices was computed for each country and is graphed as a box plot. (b) The inter-individual similarity indices presented in Fig. 4c were averaged in each block of city pairs and are displayed according to the indicated color scale. (c) Cell numbers of family Enterobacteriaceae determined by RT-qPCR. Refer to Fig. 1b for definition of box plot. Red symbols of “>”, “≫” and “≫>” indicate significantly higher (P < 0.05) than other 2, 4 and 6 cities, respectively, in pairwise Wilcox test; Blue symbols of “<”, “≪”, and“≪≪” indicate significantly lower (P < 0.05) than other 2, 4 and 8 cities, respectively, in the pairwise Wilcoxon rank sum test with Bonferroni correction.
