Primary breast tumor microbiota may predict tumor recurrence. Tumor 16S sequencing results were grouped by whether patient developed metastases within 5 years of primary tumor resection surgery (n=9) or whether patient did not develop metastases (n= 24). A. Total bacterial load was not different between primary tumors that displayed recurrence. B. Shannon diversity. Later on tumor recurrence did not impact bacterial diversity within the primary tumor. C. Relative abundance of bacterial genera in different tumor samples is visualized by bar plots. Each bar represents a single tumor and each colored box a bacterial taxon. The height of a color box represents the relative abundance of that organism within the sample. “Other” represents lower abundance taxa. D. Primary breast tumors from patients that later on developed metastases did not display differences in bacterial phylum level proportional abundances. E. At the genes level, primary breast tumors from patients that later on develop metastases have elevated proportional abundance of Brevundimonas and Staphylococcus taxa. *p<0.05 and error bars show the min to max distribution.
