Genotypic resistance to all antiretroviral classes was widespread among human immunodeficiency virus type 1 isolates failing therapy. Resistance to nonnucleoside reverse transcriptase inhibitors was found most frequently and resistance to protease inhibitors was found least frequently, most likely due to differences in the number of enzymatic amino acid substitutions leading to resistance to each particular drug class.
