Comparison of beta diversity in bronchoalveolar lavage at the operational taxonomic unit level between uninfected subjects and treated subjects infected with HIV using weighted UniFrac Distance visualized by NMDS. Subjects infected with HIV who have been treated for 1 year (A), and for 3 years (B). The population infected with HIV (red) remains significantly different compared with bronchoalveolar lavage from uninfected subjects (black) even after 1 year on therapy. This difference is slightly less after 3 years of highly active antiretroviral therapy. NMDS = nonmetric multidimensional scaling.
