As shown in Figure 3, there were four phyla represented in the PMP core microbiome; the relative abundance of each phyla was similar to what was seen for the individual tumor and mucin samples, with the majority of sequences being classified as Proteobacteria (77%), followed by Actinobacteria (15%), Firmicutes (5.7%) and Bacteroidetes (2.3%). The gene discussed is MUC5AC; the disease is neoplasm.
