The tag number of each taxonomic rank (species) or OTU in the samples were summarized in a profiling table or histogram, drawn with R(v3.1.1) software. The nonparametric Wilcoxon Rank-Sum test was used to identify OTU among different groups in QIIME. In order to determine the differences between the two groups not reported in QIIME, the OTU:s of P<0.1 in QIIME analysis were classified into generic levels, and then statistical tests were implemented using Graphpad prim6. A chi-square test was used for categorical variables. A value of P<0.05 was considered statistically significant in the comparison groups.
