An exploration of Prevotella-rich microbiomes in HIV and men who have sex with men
Abstract Background Gut microbiome characteristics associated with HIV infection are of intense research interest but a deep understanding has been challenged by confounding factors across studied populations. Notably, a Prevotella-rich microbiome described in HIV-infected populations is now underst...
