Abstrakt: Levels of neutralizing antibody to lymphocytic choriomeningitis (LCM) virus in the sera of 66 infected persons were assayed by a rapid fluorescent focus-inhibition test (RFFIT). The test was more sensitive than the mouse-neutralization (MN) test and could be completed in less than 24 h. The RFFIT titers were compared with titers obtained by the indirect fluorescent-antibody (IFA) and complement-fixation (CF) tests. Neutralizing antibody detected by the RFFIT remained positive after IRA, CF and MN antibodies had disappeared. The RFFIT for detection of LCM antibody is specific and reproducible and seems especially useful for determining the incidence and epidemiology of LCM virus infections.
