AB In the course of the global pandemic, the human immunodeficiency virus
type-1 (HIV-1) has established at least eight distinct genotypes in the
main (M), or prevalent, group of isolates, a variety of rare outlier
forms, and intergenotypic recombinants of group M viruses. This
genotypic diversity has been documented, for the most part, by
sequencing of subgenomic segments of the provirus. Using DNA from virus
cultures on peripheral blood mononuclear cells (PBMC) and recent
improvements of the PCR technique, we have amplified virtually
full-length HIV-1 genomes from genetic subtypes A through G of group M
viruses and molecularly cloned several of them. Resequencing of the
complete genome of a prototype strain after long PCR amplification and
cloning has established a PCR error rate of 0.14%. We also report the
first complete PCR-derived sequence of a U.S. clinical isolate of
genotype B expanded only in primary PBMC; this provirus harbors a
uniquely truncated V3 loop.
