They concluded that the SIVcpz strain arose in chimpanzees through a series of transmission and recombination or genetic exchange events between SIVs in two species of monkeys: The lack of transport routes into the North and East of the country accounts for the significantly fewer reports of infections there at the time.

The researchers who discovered this connection concluded that it proved chimpanzees were the source of HIV-1, and that inn virus had at some point crossed species from chimps to humans. Use these social-bookmarking links to share HIV may be a hybrid mix of monkey viruses.

HIV first began to spread along the historic trade routes of the Congo basin in the s. Rather than small incremental changes in characteristics due to straight-forward Darwinian evolution, retroviruses are capable of changing in huge jumps as a result of genetic recombination, Cribb said.

At first the disease was called all sorts of names chjmpanzees to the word ‘gay’. For all the latest ABC Science content click here. We will not hold your personal data or use it for any other purpose. These smaller monkeys infected the chimps with two different strains of SIV.


Bailes and colleagues note that chimpanzees prey on both of these species, and their territorial ranges overlap in west central Africa.

HIV may have originated orkgin separate pathogens in monkeys Pic: Byit had reached Brazzaville, about km west of Kinshasa. When it transmutes into HIV, it becomes one of the worse killers of chimpanzeea beings and Asian monkeys. You can find out more about the origins and history of HIV through our interactive timelinewhere you can read, watch, listen and explore key events from the history of the epidemic.

The same scientists then conducted more research off how SIV could have developed in the chimps. This supports the hunter theory because chimpanzeee time SIV passed from a chimpanzee to a human, it would have developed in a slightly different way within the human body, and produced a slightly different strain. Cribb also argues such findings have implications for the possible risks of transplants across species, a developing technique known as xenotransplantation. In this scenario, SIVcpz was transferred to humans as a result of chimps being killed and eaten, or their blood getting into cuts or wounds on people in the course of hunting.

Hybrid origin of SIV in chimpanzees.

Bythis subtype had caused 75 million infections. Would you like to comment on this page? It is far rarer, and less infectious than HIV There is now a wealth of evidence on how, when and where HIV first began to cause illness in humans. SIV is oorigin in African monkeys. News Video Nick Kyrgios is bitten by a spider over Christmas. Apart from suggesting the current strains of HIV are likely to recombine in an unpredictable fashion – making the task of developing vaccines and treatments even more challenging than it already is – Cribb believes the findings have important implications for our understanding of retroviruses, the group of viruses to which SIV and HIV belong.

Julian Cribb, an Australian science writer and author of a book on the origin of AIDS, believes there is no evidence to support the idea that SIVcpz arose as a result of chimpanzees eating monkeys. Leave hybtid field blank.

But the origin of SIVcpz itself has been a mystery. Many of the first cases of AIDS were recorded there too. You are here Home. Latest In Depth Value of money is based on chimpnazees Bitcoin: The area around Kinshasa is full of transport links, such as roads, railways and rivers. The AIDS-causing HIV virus is a hybrid of two monkey pathogens that swapped genes inside a chimpanzee, becoming the deadly global epidemic it is today, an international sv of scientists report.
