Serological survey for two simian retroviruses in macaques and African green monkeys.
Colonies of nonhuman primates at the Bowman Gray School of Medicine (BGSM) were tested for antibodies to two retroviruses associated with immunodeficiency by indirect immunofluorescence (IFA) and western blot. A total of 471 cynomolgus macaques (Macaca fascicularis), 144 rhesus monkeys (M. mulatta) and 67 stumptail monkey M. arctoides) were tested for SRV-1, and 152 African green monkeys (Cercopithecus aethiops) were tested for SIV. Of the macaques tested, 170 (36%) cynomolgus, 5 (3%) rhesus and 8 (12%) stumptails were positive for SRV-1 antibodies by IFA. Of the African green monkeys, 54 (36%) were IFA positive for SIV antibodies. A total of 143 African green monkeys tested by IFA also were tested by western blot. In the African green monkeys, the IFA had a positive predictive value of 98% and a negative predictive value of 96%. Of 176 IFA positive macaque sera tested by western blot, 49 (28%) were positive, 55 (31%) were considered equivocal (only one band, usually to p27 core protein), and 72 (41%) were negative.
