Monkey viruses related to HIV may have swept across Africa more recently than previously thought, according to new research from The University of Arizona in Tucson. A new family tree for African green monkeys shows that an HIV-like virus, simian immunodeficiency virus, or SIV, first infected those monkeys after the lineage split into four species. The new research reveals the split happened about 3 million years ago. Previously, scientists thought SIV infected an ancestor of green monkeys...

WASHINGTON -- Mutations in a single gene may have turned the AIDS virus from a fairly benign infection of monkeys and apes into a global pandemic that has killed more than 25 million people in 25 years, researchers said on Thursday. The virus in humans appears to have lost a genetic characteristic that protected the immune system in apes and monkeys, the researchers report in this week's issue of the journal Cell. "The observed difference in Nef function may provide -- for the first time -- a...

By Maggie Fox, Health and Science Correspondent WASHINGTON -- A shot that helps keep AIDS-infected monkeys alive may offer the best clues yet about how to make an effective HIV vaccine, researchers reported on Thursday. The experiment provided important clues about how the AIDS virus destroys the immune system, and how to track the health of infected people, the researchers said. "A vaccine of this type does not appear to prevent infection," Dr. Norman Letvin of Harvard Medical School in...

By Maggie Fox, Health and Science Correspondent DENVER -- An injection of two drugs normally used to treat HIV patients completely protected monkeys from becoming infected with the AIDS virus, U.S. researchers reported on Monday. While it is too early to tell whether people can pop a pill and escape infection, the study provides the strongest evidence yet that it might be possible, the researchers said. Dr. Walid Heneine of the Centers for Disease and Prevention studied rhesus monkeys that...

Experiments in female monkeys have for the first time shown that when used in combination, vaginal gels known as microbicides can protect against an HIV-like virus. The research, funded largely by the National Institute of Allergy and Infectious Diseases (NIAID), one of the National Institutes of Health (NIH), suggests that similar combination microbicides could potentially provide a safe, effective and practical way to prevent HIV transmission to women, according to study investigators. The...

Research with female monkeys at the Tulane National Primate Research Center has for the first time shown that three different anti-viral agents in a vaginal gel protect the animals against an HIV-like virus. The research suggests that a microbicide using compounds that inhibit the processes by which HIV attaches to and enters target cells could potentially provide a safe, effective and practical way to prevent HIV transmission in women, according to study investigators. The study, published...

Scientists have identified the first reported case in Asia of primate-to-human transmission of simian foamy virus (SFV), a retrovirus found in macaques and other primates that so far has not been shown to cause disease in humans. The transmission of the virus from a monkey to a human took place at a monkey temple in Bali, Indonesia, the researchers report in the July issue of the journal Emerging Infectious Diseases. Even though this particular virus jumping to humans may not prove dangerous,...

DURBAN -- Chimpanzees may hold vital clues for mankind's war against the AIDS virus, but the apes could be wiped out before they reveal their secrets, a leading genetic expert warned on Wednesday. Paul Sharp of Britain's University of Nottingham told an AIDS conference in Durban that the latest research indicated that chimpanzees -- humanity's closest living relative -- were an important but increasingly endangered resource for scientists hoping to better understand the HIV virus....

Sooty Mangabey, Cercocebus atys
2012-06-28 20:49:18

The sooty mangabey (Cercocebus atys) is an Old World Monkey that can be found throughout the area stretching from Senegal to eastern Ghana. Its other common names include the white-naped mangabey, the white-crowned mangabey, and the white-collared mangabey, which causes some confusion with the collared mangabey. There are currently two recognized subspecies of this mangabey, although they can be considered distinct species. The sooty mangabey resides in forests within its range, preferring...

Simian immunodeficiency virus (SIV), also known as African Green Monkey virus, is a retrovirus able to infect at least 33 species of African primates. SIV has been present in monkeys and apes for at least 32,000 years, probably longer. Strains from two of these primate species have crossed the barriers into humans resulting in HIV-2 and HIV-1. Contraction involves contact with the blood of chimps that are often hunted for bushmeat in Africa. SIV infections appear in many cases to be...
