Susceptibility of Chinese rhesus monkeys to SIV infection

The use of China-derived monkeys in AIDS research has been limited by reports of reduced susceptibility to SIV. We performed a serial passage of SIV in Chinese macaques, which resulted in a viral stock capable of inducing simian AIDS and high levels of replication in these animals. Similar to HIV in humans, SIV pathogenesis in non-human primates is not limited by geographical origin. Chinese macaques are useful in pathogenesis, vaccine, and therapeutic studies in AIDS.
