Description: Differentially represented taxa between normal breast tissue samples (from cancer-free donors) and breast tumour tissue. (A) Comparison of the microbiome in primary tumours of Slovak patients and normal breast tissue of Slovak cancer-free donors. Since standard conditions identified too many results, to visualise data, LEfSe was run with parameters (LDA > 3, Kruskal Wallis testp-value < 0.05, Wilcoxon testp-value < 0.05)
