The composition, relative abundance, and diversity of oral microbiota in HIV-infected groups and controls (A) at the phylum level; (B) at the genus level; (C) Alpha diversity exemplified by the Chao1 index; (D) Alpha diversity exemplified by the Shannon index; (E) Beta diversity represented by Principal coordinate analysis (PcoA) of unweighted UniFrac distances; (F) Beta diversity represented by Principal coordinate analysis (PcoA) of weighted UniFrac distances. A0, people living with acute HIV infection at baseline; B0, people living with chronic HIV infection at baseline; D, HIV-uninfected controls; A12, people living with acute HIV infection after 12 weeks of ART; B12, people living with chronic HIV infection after 12 weeks of ART. *p < 0.05; **p < 0.01; ***p < 0.001.
