Causes AIDS in man

The simian sarcoma virus (SSV) and its associated helper virus, simian sarcoma associated virus (SSAV) were isolated from a spontaneous fibrosarcoma in a pet woolly monkey. These viruses were, in retrospect, actually the first isolate of the GaLV group. SSAV is genetically as similar to the other members of the GaLV group as the latter are to each other. The woolly monkey from which SSV was isolated lived in the same household as a pet gibbon ape, and it has become clear, from the otherwise restricted distribution of GaLV to gibbons and their absence in New World monkeys, that the woolly monkey was infected by a strain of GaLV from the gibbon.
