Using monoclonal antibodies, which bind to specific proteins and thus act like biological homing pigeons, the Einstein researchers eventually isolated and identified A-68. Subsequent autopsies, as well as two rare brain biopsies of living Alzheimer's patients, confirmed that A-68 is unique to the disease, and further tests showed it can be found in spinal fluid...
...disclosed the existence of LAV-II in March, after finding the new AIDS virus in the blood of two West Africans. At the time, Montagnier's colleague Dr. Francois Clavel warned that LAV-II could elude current blood-screening tests for AIDS.

Subsequent testing of West Africans, however, turned up 63 more victims infected with LAV-II; eleven of them have contracted AIDS, and ten have AIDS-related illnesses. Though no American has yet been found to harbor the new virus, Montagnier reported that...

Studies of the sex partners of AIDS victims -- people who have had hundreds of sexual encounters with carriers of the virus -- show that 40% to 50% do not become infected with the virus...
