Phenotypic and Genotypic Analysis of Biologically Cloned Human Immunodeficiency Virus Type 1 Isolates from Patients Treated with Zidovudine and Lamivudine

摘要

Mutations at reverse transcriptase codons 44, 118, 207, and 208 were significantly correlated with reduced zidovudine susceptibility in biologically cloned human immunodeficiency virus type 1 (HIV-1) isolates. Sequences from the Stanford HIV RT and Protease Sequence Database showed that these mutations were more common in HIV-1 isolates from patients treated with zidovudine and lamivudine than in patients not treated with these drugs.
