FIG. 2.
Relative contributions of detected bacterial phyla with pyrosequencing using four different forward primers and HITChip analysis for community data at level 1. Pearson product-moment correlation coefficients (r) between pairs of profiles are shown above the bars. The phylum Firmicutes was subdivided into Bacilli, Clostridium clusters, uncultured Mollicutes, and uncultured Clostridiales. Pyrosequences that could not be classified above the confidence threshold of 80% are grouped to Unclassified_Human unique OTU, which is indicated in the microbial profiles with shadowing (black bars). Phylogenetic groups that contribute at least 1% to one of the profiles are indicated in the color key.
