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 …

Simian immunodeficiency viruses (SIVs) can be found naturally in a large number of African
primate species; already 31 species have been identified with serological evidence of SIV …

Primate lentiviruses (PLV) from closely related primate species have been observed to be
more closely related to each other than to PLV from more distantly related primate species …

Simian immunodeficiency viruses (SIVs) are found in an extensive number of African
primates and humans continue to be exposed to these viruses by hunting and handling of …

The human immunodeficiency viruses (HIV-1 and-2) together with the simian
immunodeficiency viruses (SIV) comprise the primate lentivirus family. Since the isolation of …

Lentiviruses are one of several groups of retroviruses. In early studies of the molecular
phylogenetic analysis of endogenous and exogenous retroviruses it was suggested that the …

The genomes of the four primate lentiviral groups are complex and contain several
regulatory or accessory genes. Two of these genes, vpr and vpx, are found in various …

Lentiviruses chronically infect a broad range of mammalian species and have been
transmitted from primates to humans, giving rise to multiple outbreaks of HIV infection over …

Studies of primate lentivirus phylogeny over the past decade have established a minimum of
five related, but genetically distinct, groups of simian immunodeficiency virus (SIV), each …

Simian immunodeficiency viruses (SIV) and the closely related human immunodeficiency
viruses (HIV-1 and HIV-2) belong to the lentivirus subfamily of retroviruses. SIVs are a large …
