Human gut microbiota analysis from different racial/ethnic groups. The 16S rRNA gene (v1-v3 regions) was sequenced from fecal samples using 454 Jr. sequencing and analyzed using QIIME platform. A: The phylum distribution among different groups was generated by comparing with the GreenGene (gg_otus-4feb2011) data base; B: The ratio of Firmicutes and Bacteroidetes is represented among different racial/ethnic groups. Statistics were performed using unpaired two-tailed t test using Graphpad Prism 4.0 software (aP < 0.05 vs control).
