Figure 1. Survey of microbial communities residing in breast tissue from breast cancer patients.

Figure 1

A) Phylum level distribution of microbial communities comparing paired normal adjacent (“paired normal”) and breast cancer tissue from 20 patients with ER-positive breast cancer (n = 20). Each bar represents 100% of the bacteria detected in a given sample. B) Combined distribution at the phylum level in paired normal and breast tumor tissue (n = 20). C) Number of OTUs found in each community (n = 20). D) Analysis of OTUs with differential abundance between paired normal and tumor tissue (n = 20). E) Correlation of relative abundances of M. radiotolerans and S. yanoikuyae (n = 20). F) Relative abundances of commonly found skin bacteria (n = 20). p-values from Student’s paired t-test are shown, with P<0.05 considered significant. Error bars represent mean ± s.e.m.
