Conn. 06516). Epidemiologic studies of latent virus infections in captive monkeys and baboons. II. Serologic evidence of myxovirus infections with special reference to SV6. Atner. J. Epid., 1969, 89: 472-479.—From February through December 1966, a total of 365 pairs of sera were collected from rhesus and green monkeys and baboons while they were kept in captivity. Both rhesus and green monkeys showed a low rate of SVj and parainfluenza 3 virus infections at the time of arrival at the local laboratories as determined by the neutralization tests, but showed an average conversion rate of 3 0 % to parainfluenza 3 and 5 0 % to SVj during 3 0- 9 0 days of quarantine. None of the 193 paired sera tested showed antibody titers to either parainfluenza 1 or parainfluenza 2. On the other hand, both rhesus and green monkeys, as well as baboons, showed a high incidence of group A influenza anti-s antibody titers, but no inhibition could be demonstrated when these sera were tested against PR8, FM1, Jap /305 /57, Taiwan/1/64, and swine viruses. The specificity of the influenza A anti-s titers in monkey sera is under investigation
