title: Association of SAIDS/RF-related signs with current or past SAIDS type 2 retrovirus infection in a colony of Celebes black macaques.
abstract: The 83 members of the Celebes black macaque (Macaca nigra) colony were screened for viremia with simian acquired immunodeficiency syndrome (SAIDS) type 2 retrovirus and antibodies against the retrovirus. On the basis of this screening, the Celebes colony was divided into four groups: retrovirus-positive/seropositive (virus+/Ab+); retrovirus-negative/seropositive (virus-/Ab+); retrovirus-positive/seronegative (virus+/Ab-); and retrovirus-negative/seronegative (virus-/Ab-). Monkeys in the virus+/Ab+ group displayed more major clinical signs and required medication more times than monkeys in the other groups. In contrast, monkeys in the virus-/Ab- group had fewer health problems than monkeys in the other groups. The five monkeys that had surgically confirmed retroperitoneal fibromatosis (RF), palpable abdominal masses, or both, were in the virus+/Ab+ group. Some of the monkeys in groups with current or past retrovirus infection were well clinically. There were no statistically significant differences in the mitogen reactivities of mononuclear cells obtained from monkeys of the different groups.
