Laboratory evaluation demonstrates genetic divergence between primary cells and cultured isolates in zidovudine-resistant HIV-1, highlighting limitations of relying solely on viral stocks.

Key Points

To evaluate the efficacy of self-sustained sequence replication amplification combined with bead-based sandwich hybridization for detecting zidovudine-resistance mutations in HIV-1 RNA.
Extracted viral RNA from HIV-1-infected peripheral blood mononuclear cells (PBMCs) and cultured viral stocks to assess pol gene codons 67, 70, 215, and 219.
Performed self-sustained sequence replication (3SR) amplification coupled with differential bead-based sandwich hybridization (BBSH), validating results via dideoxynucleotide sequencing and comparing with PCR and Southern hybridization.
Genotype determinations by 3SR and BBSH were corroborated by dideoxynucleotide sequencing, identifying mutations associated with zidovudine resistance.
Genotypes differed between uncultured PBMCs and corresponding cocultured HIV-1 isolates at the monitored codons, with isolates sharing identical resistance genotypes showing a threefold variation in ID50 measurements.
