A direct comparison of drug susceptibility to HW Type 1 from antiretroviral experienced subjects as assessed by the antivirogram and phenosense assays and by seven resistance algorithms.
Using the Antivirogram assay (Virco, Belgium) phenotypic resistance to lamivudine, emtricitabine, abacavir, didanosine and tenofovir was observed, with preserved susceptibility to zidovudine and stavudine (Table 3).
