Antibodies against measles virus (MV) and canine distemper virus (CDV) were measured by solid‐phase radioimmunoassay (RIA) of sera and cere‐brospinal fluid (CSF) from 28 patients with multiple sclerosis (MS) and matched neurological controls. When the groups were compared for MV antibody titers and CDV antibody titers of sera and MV/CDV serum antibody titer ratios, no significant difference was found. The CDV antibody titers and the MV antibody titers were in good correlation. CDV antibodies showed RIA titration curves typical of low avidity antibodies. In tests for MV antibodies in CSF, 82% of the MS patients and 19% of the controls were positive, whereas 36% of the MS patients and 4% of the controls were positive in CDV RIA. The correlation between MV and CDV antibody levels, the low avidity of CDV antibodies and the fact that absorption of the specimens with MV antigen abolished all CDV antibody activity suggest that the CDV antibodies are MV antibodies cross‐reacting with CDV. It is concluded that canine distemper virus is unlikely to be involved in the etiology of multiple sclerosis.
