Abstract: This present invention provides a method for monitoring ARV resistance, to determine viral fitness, and to forecast possible drug failure. The method provides improved personalized HIV/AIDS care to the patient-physician over existing assays at a reduced cost. This set of assays will utilize the same PCR amplicon of the patient HIV genome, which encompasses all of the drug targeted HIV-1 genes (polPR-RT-IN-envgp120-gp41) and not just PR-RT as with the prior systems. The greatest advantage of this method over previous is the rapid cloning of this amplicon into an HIV-1 genome vector through yeast recombination/gap repair. The vectors can be directly passed from yeast to mammalian cell line which has been specifically engineered to produce replication competent HIV-1 particles and to test susceptibility to all ARVs, i.e. PRIs, NRTIs, NNRTIs, T20, as well as entry and integrase inhibitors in development/clinical trials.
