A continual increase in intrapatient HIV-1 heterogeneity is thought to contribute to evasion of host immune response and eventual progression to AIDS. Tuberculosis (TB) is diagnosed both early and late during the course of HIV-1 disease and may increase diversity of HIV-1 quasispecies by activating the HIV-1 immune response and increasing HIV-1 replication. We examined whether HIV-1 heterogeneity is altered in HIV-1-infected individuals with TB.
