Abstract

The course of simian retrovirus type 1 (SRV-1) infection was studied in 14 experimentally inoculated juvenile rhesus monkeys. Viral transmembrane protein antigenemia and antibodies to whole virus were measured by enzyme-linked immunosorbent assay and correlated with the clinical course of disease and virus isolation. Based on these parameters, animals with simian retrovirus type 1-induced disease were divided into three categories: (a) monkeys dying within a few months of fulminating simian acquired immunodeficiency syndrome in the face of a high level persistent antigenemia and viremia, and a nondetectable serum antibody response; (b) monkeys that developed a milder form of simian acquired immunodeficiency syndrome but remained alive in spite of a chronic low-grade antigenemia and viremia and only a transient initial antibody response; and (c) monkeys that never became ill and that were either transiently or nontransiently viremic and antigenemic. This latter group developed high levels of serum antibodies. The outcome of simian retrovirus type 1-induced disease was similar to that described for feline leukemia virus infection of cats, another retroviral disease of animals. The disease course differed considerably, however, from that reported for retrovirus-induced human acquired immunodeficiency syndrome.
