SEROLOGICAL SURVEY OF A CAPTIVE MACAQUE COLONY IN CHINA FOR ANTIBODIES TO SIMIAN TYPE-D RETROVIRUSES

Sera from 510 macaques consisting of Macaca mulatta, Macaca assamensis, Macaca fascicularis, Macaca nemestrina, and Macaca arctoides were investigated for antibodies to simian AIDS type D retrovirus (SRV) by ELISA and Western blot with viral antigens purified from supernatants of SRV-1 infected cell cultures. Of these monkeys, 104 were seropositive by ELISA; only 23 were confirmed by Western blot. The true positive reaction to SRV was found in 15 of 463 (3.2%) M. mulatta and eight of eleven (72.7%) M. assamensis.
