The causes of false-positives encountered during the screening of old-world primates for antibodies to human and simian retroviruses by ELISA	1986-11-30		.txt	text/plain	3923	190	51	False-positive ELISA antibody tests were particularly common among sera from mandrills, crab-eating macaques, lion-tailed macaques, African green monkeys, and DeBrazza's and moustached guenons. False positive ELISA antibody tests, while sporadically encountered among most of the 50 species of oldworld primates, were especially prevalent in Mandrillus sphinx (mandrills), Macaca fasicularis (crab-eating macaques) , Macaca sifensus (lion-tailed macaques), Cercopithecus aethiops (African green monkeys), Cercopithecus neglectus (De-Brazza's guenons), Cercopithecus cephus (moustached guenons) and Miopithecus talapoin (talapoins) . Specific antibodies to HTLV-III were found in 23 monkeys, 4/7 sooty mangabys, 11/15 talapoins, 2/11 False-positive ELISA antibody reactions to one or more viruses were found in a low proportion of individuals from many different species of old-world primates (Table 1) . Studies with African green monkey sera established the cause of false-positive ELISA antibody tests in this species; sera appeared to contain a specific antibody or antibodies that was directed against cell-associated protein(s) that were co-purified with the various virus preparations.	./cache/cord-317223-juw4xt8q.txt	./txt/cord-317223-juw4xt8q.txt
