RESUMO

We used a focal infectivity assay with HeLa H1-JC.37 cells to directly compare susceptibilities of simian immunodeficiency virus (SIV) and human immunodeficiency virus type 1 (HIV-1) to protease inhibitors. SIVmac239 was inhibited by indinavir, saquinavir, and ritonavir, with 50% effective concentrations (means ± standard deviations) of 39 ± 8, 55 ± 3, and 13 ± 5 nM, respectively. The corresponding values for inhibition of HIV-1 were 66 ± 4, 47 ± 10, and 25 ± 14 nM, respectively.
