To clarify the origin and evolution of the primate lentiviruses (PLVs), which include human
immunodeficiency virus types 1 and 2 as well as their simian relatives, simian …

In the absence of direct epidemiological evidence, molecular evolutionary studies of primate
lentiviruses provide the most definitive information about the origins of human …

Exploration of the diversity among primate lentiviruses is necessary to elucidate the origins
and evolution of immunodeficiency viruses. During a serological survey in Cameroon, we …

The human immunodeficiency virus types 1 and 2 (HIV-1 and HIV-2) appear to have
originated by cross-species transmission of simian immunodeficiency virus (SIV) from …

Introduction 3. Discovery of SIVs in African non-human primate species: the path from the
discovery of the simian origin of HIVs to the characterization of the largest and most diverse …

With the exception of human immunodeficiency virus (HIV), which emerged in humans after
cross-species transmissions of simian immunodeficiency viruses from nonhuman primates …

Two related but distinct viruses have been shown to cause AIDS in humans. These viruses,
human immunodeficiency virus type 1 and type 2 (HIV-l and HIV-2), are members of what is …

Acquired immune deficiency syndrome (AIDS) can be caused by either of two retroviruses,
known as human immunodeficiency virus types 1 and 2 (HIV-l and HIV-2). Related viruses …

We designed a universal primer (UNIPOL) for DNA amplification of AIDS-related viruses.
The phylogenetic tree constructed from the presumed sequences amplified with UNIPOL …

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 …
