Species of the genus LENTIVIRUS, subgenus primate immunodeficiency viruses (IMMUNODEFICIENCY VIRUSES, PRIMATE), that induces acquired immunodeficiency syndrome in monkeys and apes (SAIDS). (lookformedical.com)
Longer sequence data, or full genomes from a greater representation of Asian primates, including gibbons, leaf monkeys, and Sumatran orangutans are needed to fully elucidate these evolutionary dates and relationships using the model criteria suggested herein. (bvsalud.org)
Simian2
While human T-lymphotropic virus type 1 (HTLV-1) originates from ancient cross-species transmission of simian T-lymphotropic virus type 1 (STLV-1) from infected nonhuman primates, much debate exists on whether the first HTLV-1 occurred in Africa, or in Asia during early human evolution and migration. (bvsalud.org)
Four types of human T cell lymphotropic viruses (HTLV) have been described (HTLV-1 to HTLV-4) with three of them having closely related simian virus analogues named STLV-1, -2, and -3. (bvsalud.org)
Human immun2
External envelope protein of the human immunodeficiency virus which is encoded by the HIV env gene. (lookformedical.com)
Transmembrane envelope protein of the HUMAN IMMUNODEFICIENCY VIRUS which is encoded by the HIV env gene. (lookformedical.com)
Type1
Human T-cell leukemia/lymphoma virus type 1 (HTLV-1) was the first oncogenic human retrovirus discovered in 1980. (bvsalud.org)
Primates9
Description of a new species of Hoolock gibbon (Primates: Hylobatidae) based on integrative taxonomy. (academictree.org)
Nonhuman primates can be naturally infected with a plethora of viruses with zoonotic potential, including retroviruses. (bioone.org)
These simian viruses present risks to both captive nonhuman primate populations and persons exposed to nonhuman primates. (bioone.org)
Simian retroviruses, including simian immunodeficiency virus, simian type D retrovirus, simian T-lymphotropic virus, and gibbon ape leukemia virus, have been shown to cause clinical disease in nonhuman primates. (bioone.org)
In contrast, simian foamy virus, a retrovirus that is highly prevalent in most nonhuman primates, has not been associated with clinical disease in naturally infected primates. (bioone.org)

A suborder of PRIMATES consisting of six families: CEBIDAE (some New World monkeys), ATELIDAE (some New World monkeys), CERCOPITHECIDAE (Old World monkeys), HYLOBATIDAE (gibbons and siamangs), CALLITRICHINAE (marmosets and tamarins), and HOMINIDAE (humans and great apes). (lookformedical.com)
It is unclear if nonhuman primates also serve as a reservoir of human dengue viruses under certain conditions. (lookformedical.com)
Simian4
Although it has been shown that human retrovirus infections with human T-lymphotropic virus and human immunodeficiency virus originated through multiple independent introductions of simian retroviruses into human populations that then spread globally, little is known about the frequency of such zoonotic events. (bioone.org)
Four types of human T cell lymphotropic viruses (HTLV) have been described (HTLV-1 to HTLV-4) with three of them having closely related simian virus analogues named STLV-1, -2, and -3. (bvsalud.org)
This virus serologically cross-reacts with simian T-cell leukemia virus, which may be the causative agent of the present neoplasm. (lookformedical.com)
Lymphoma2
Human T-cell leukemia/lymphoma virus type 1 (HTLV-1) was the first oncogenic human retrovirus discovered in 1980. (bvsalud.org)
The neoplastic cells, which were highly pleomorphic, resembled those in adult T-cell lymphoma-leukemia in humans. (lookformedical.com)
Multiple1
Multiple isolates of viruses or transposable elements are considered distinct if at least one promoter region fails to fulfill the above similarity criterion. (expasy.org)
