Immunoglobulin M specific for measles in serum and cerebrospinal fluid of patients with multiple sclerosis and other neurological diseases.

Serum and cerebrospinal fluid of patients with multiple sclerosis, subacute sclerosing panencephalitis and other neurological disease have been tested by the indirect fluorescent antibody method for immunoglobulin M specific for measles. Only sera of three patients were positive. This feature is of little statistical importance. Nevertheless the authors emphasize the role of a possible viral infection in the pathogenesis of multiple sclerosis.
