Longitudinal cervicovaginal bacteriome and virome alterations associate with discordant shedding and ART duration in women living with HIV in Peru.

ABSTRACT: Despite successful suppression of plasma HIV replication by antiretroviral therapy (ART), some women living with HIV (WLHIV) can still experience genital HIV shedding (discordant shedding). Female genital tract (FGT) bacterial and viral microbiome (bacteriome and virome) community dynamics during long-term ART in WLHIV are poorly understood but might contribute to discordant HIV shedding, as the bacteriome and virome are known to influence FGT health. Here, using metagenomic next-generation sequencing, we characterize the bacteriome and virome in 125 cervicovaginal specimens collected over two years from 31 WLHIV in Lima, Peru, and show that FGT bacteriome instability is associated with discordant HIV shedding, while longitudinal changes in FGT virome composition are associated with ART du
