Microbiota abundance for household control (HC) and Parkinson’s disease (PD) groups. The relative abundance of phylogenetic gut microbiome taxa composition at the (A) genus, (B) family, (C) order, and (D) phylum level for individual participants (n = 81 HCs and n = 103 PD) showed a statistically significant compositional difference between PD and HC groups at each studied taxonomic level (PERMANOVA, p < 0.01 genus, p < 0.01 family, p < 0.01 order, p = 0.02 phylum).
