Differentially abundant genera according to HIV infection and related factors. Data are means (SD) of relative abundance of 4 genera (Ruminococcus, Oscillospira, Bifidobacterium, and Collinsella) among (A) 57 individuals without HIV, 93 individuals with HIV with high CD4 counts (≥500 cells/mm³), and 35 individuals with HIV with low CD4 counts (<500 cells/mm³) and (B) 57 individuals without HIV, 94 individuals with aviremic HIV (undetectable viral load ≤20 copies/mL), and 34 individuals with viremic HIV (viral load >20 copies/mL). *P < .05; **P < .01. Abbreviations: HIV, human immunodeficiency virus; SD, standard deviation; –, negative; +, positive.
