The phylogenetic complexity of the primate lentiviruses is legendary and our understanding
of its scope was dramatically increased recently by the discovery of a new branch of the HIV …

The known universe of HIV-1 viruses is divided into two groups, a major “M” group and an
outlier “O” group,(reviewed in [9]). HIV-1 subtypes are clusters of sequences within the M …

Retroviruses are highly recombinogenic, but recombination can only occur between
genomes packaged within the same virion. Until about 1994, it was generally thought that …

HIV-1's are currently divided into two genetic groups, based on phylogenetic reconstruction
using DNA sequences. The majority of these sequences fall into the M (major) group, while …

Infectious molecular clones of the human immunodeficiency virus type 2 (HIV-2) will be
valuable tools for the study of regulatory gene functions and the development of an animal …

THE RAPID VIRAL TURNOVER and high mutation rate of HIV-1 result in remarkable genetic
variation among strains obtained from different parts of the world. 1 This has led to the …

The highly variable genome of the Human Immunodeficiency Virus Type-1 (HIV-1) has been
extensively studied for more than a decade. Over several years, multiple, distinct genotypes …

Thediverse GENOMic sequences of the worldwide human immunodeficiency virus type 1
(HIV-1) epidemic can be classified into discrete subtypes by their phylogenetic relation …

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 …

The picture of HIV-1 genetic diversity in the global pandemic continues to evolve.
Identification of new variants, including circulating and unique recombinant forms …
