The picture of dynamic interaction between oncogenic viruses and the vaginal bacteria-immune host milieu is incomplete. We evaluated the impact of , , and oncoviruses on the vaginal Community State Types (CSTs) and host immune response in reproductive-age women. In our cohort, only and were detected and were associated with changes in the resident bacteria of CST I and IV ( < 0.05). increased in CST I while and increased in CST IV. Conversely, CST II and III showed an alteration of the immune response, with the decrease of Eotaxin, MCP-1, IL-7, IL-9, and IL-15 ( < 0.05), leading to reduced antiviral efficacy. An efficient viral clearance was observed only in women from CST I, dominated by . Our in vivo study begins to address the knowledge gap with respect to the role of vaginal bacteria and immune response in susceptibility to oncoviral infections.
