Beta diversity of the penile microbiota. Principal Coordinates Analysis (PCoA) plots of the weighted UniFrac distances of the penile microbiota coloured according to a) high-risk human papillomavirus (HR-HPV) infection status, b) human immunodeficiency virus (HIV) infection status, c) HIV and HR-HPV infection, and d) CD4+ T-cell count status. The first two principal coordinate axes of variations and the percentage variation explained by each (Axis.1: 45.3% and Axis.2: 14.9% (a-c); and Axis.1: 42.9% and Axis.2: 16.0% (d)) are shown. Each solid point is a bacterial community
