Comparison of serological tests for the detection of antibody to natural and experimental murine cytomegalovirus.

[摘要] Three serological tests, i.e. complement fixation test, indirect immunofluorescent assay, and enzyme-linked immunosorbent assay (ELISA) were compared for sensitivity in the detection and titration of murine cytomegalovirus antibody. The three tests were compared using sera from experimentally inoculated and naturally infected mice bled at intervals from 3 to 140 days postinfection. In the acute infection, complement fixation and indirect immunofluorescent assay tests were of comparable sensitivity for early detection of antibody, whereas the ELISA was less sensitive. In persistent infection, higher titers were recorded with ELISA. Since murine cytomegalovirus has been shown to exert significant effects on the immune response of infected mice, this antigen should be included routinely in viral antibody screening programs.
