SRV-3; Mason Pfizer monkey virus; monkey virus, Mason-Pfizer; retrovirus 1, Simian; retrovirus 2, Simian
A species of BETARETROVIRUS isolated from mammary carcinoma in rhesus monkeys. It appears to have evolved from a recombination between a murine B oncovirus and a primate C oncovirus related to the baboon endogenous virus. Several serologically distinct strains exist. MPMV induces simian AIDS (SAIDS).
