Two of four strains of the virus that can cause AIDS come from gorillas in southwestern Cameroon, an international team of scientists reported in studies published Monday in the United States.
The new information means that researchers now know the origins of all strains of the HIV virus that occur in people.
HIV (HIV-1) has at least four strains. Known as Groups M, N, O and P, each one had its own origin – from ape to man, on at least four separate occasions.
Groups M and N were known to have come from chimpanzees in Cameroon. But until now the origin of the O and P strains had been unknown. …
Group P has only been detected in two people so far. And Group O has been found in central and western Africa, infecting about 100,000.
The breakthrough was made possible thanks to genetic samples from chimpanzees and gorillas from Cameroon, Gabon, Uganda and the Democratic Republic of Congo.
