The distribution of neutralizing antibody to Yaba virus and 1211 agent in the sera of three Asian and one African monkey species was examined.
Cynomolgus (Macaca irus), bonnet (M. radiata) and rhesus (M. mulatta) monkeys possessed antibody to Yaba virus at incidences of 19·9, 8·4 and 0%, respectively. In African green monkeys (Cercopithecus aethiops) the incidence was as high as 76·4%.
As for 1211 agent, no Asian monkeys had neutralizing antibody and 5·5% of African green monkey sera neutralized the virus.
