The prevalence of antibodies to 3 retroviruses in the macaque colony of the New England Regional Primate Research Center (NERPRC) was determined using enzyme‐linked immunosorbent assay procedures as well as radioimmunoprecipitation‐SDS polyacrylamide gel electrophoresis and indirect immunofluorescence tests. Out of 848 macaques, 3 (0.35%) had antibodies to simian immunodeficiency virus (SIV), 27 (3.2%) had antibodies to simian T‐lymphotropic virus type I (STLV‐I) and approximately 285 (34%) had antibodies to type D retrovirus. Of 3 macaques infected with SIV, 2 were rhesus monkeys (Macaca mulatta) and I was a cynomolgus monkey (Macaca fascicularis). STLV‐I and D retrovirus infection occurred in all 4 macaque species examined. SIV, STLV‐I and D retroviruses were isolated from sero‐positive macaques. The low prevalence of SIV infection suggests that SIV is not being readily transmitted among macaques at NERPRC; this contrasts markedly with the high SIV prevalence in some captive mangabey colonies. In contrast to African green monkeys from eastern Africa, 160 Caribbean green monkeys examined showed no sign of SIV infection. These results provide a framework for monitoring spontaneous disease associated with infection by these 3 retroviruses and will help in further definition of STLV‐I and SIV infection of non‐human primates as animal models for human disease.
