Competitive radioimmunoassay to detect antibodies to herpes B virus and SA8 virus.

摘要

A monoclonal competitive radioimmunoassay (CompRIAm) which detects antibody to herpesvirus simiae (B virus) in monkey and human sera and antibody to SA8 virus in monkey sera but not antibody to herpes simplex virus in human sera is described. Of 232 serum samples from wild-caught cynomolgus monkeys, 117 serum samples were positive when tested by CompRIAm. The results were in close agreement (97.5%) with B virus neutralizing antibody results on the same sera. Sera from 97 wild-caught rhesus monkeys and 92 wild-caught baboons were also tested. The CompRIAm was able to differentiate between sera that had neutralizing antibody to B virus and SA8 virus and those that did not, although the discrimination was not as clear as that in the tests on cynomolgus monkey sera. Sequential sera from two humans with confirmed cases of B virus infection were tested by CompRIAm. B virus antibody was detected in sera from both humans. None of 237 other serum samples from blood donors and patients attending sexually transmitted disease clinics reacted in the CompRIAm.
