Gorillas are the source of a form of HIV/AIDS in human beings
Scientists in Cameroon say that simian immunodeficiency viruses (SIVs) that are more closely related to HIV-1 Group O than any other simian virus yet detected are endemic within the gorilla population.
A report of their study in the journal Nature suggests that the virus was transmitted to people who butcher gorillas as part of the bushmeat or traditional medicine trades.
HIV-1 has been shown to come from three sources. In two cases chimpanzees were found to be the origin, but the third was a mystery. Analysis suggests it was transmitted to gorillas from chimpanzees, although the route has still to be established.
