Both HIV infection and antiretroviral therapy(ART)affect the oral *** successful treatment with ART in people living with HIV(PLWH),which leads to a significant decline in viral loads and immune reconstitution,is associated with changes in or recovery of the oral microbiome remains ***,we performed a cross-sectional study of 118 PLWH receiving regular ART and 40 healthy controls(HCs).Among the 118 PLWH,18 immunological nonresponders(INRs;immunological responders(IRs;≥500 CD4^(+)T cells/μL)were *** oral microbiota composition of all participants was analyzed using 16S rRNA gene sequencing of throat swab *** abundance of bacterial genera was compared between IRs and INRs,and Pearson correlations between bacterial abundance and peripheral blood immune cell counts were *** INR group showed lower alpha diversity than the IR and HC groups,which displayed similar alpha *** genera Alloprevotella,Prevotella and Neisseria were more abundant in PLWH than in HCs,whereas the genera Rothia,Streptococcus and Fusobacterium were more abundant in HCs than in *** genus Rothia was more abundant in the INR group,whereas Prevotella,Alloprevotella,Porphyromonas and Haemophilus were more abundant in the IR *** genera Rothia and Alloprevotella were negatively and positively associated with CD4^(+)T cell counts,***,an increased abundance of Rothia in the oral microbiome is associated with unfavorable outcomes regarding immune reconstitution in PLWH receiving regular ART,whereas Prevotella,Alloprevotella,Porphyromonas and Haemophilus are associated with favorable outcomes.
