Isolation and genotype analysis of rubella virus from a case of Guillain-Barré syndrome.

Rubella virus (RV) infection has sporadically been linked to Guillain-Barré syndrome (GBS), but the association with RV has been based only on clinical and/or serological backgrounds. In the present case it was possible to isolate RV (genotype 1a) from cerebrospinal fluid and peripheral blood mononuclear cells of an 18-year-old woman diagnosed with GBS after clinical manifestations of rubella. This report contributes to confirm RV as one of the triggering pathogens of this peripheral nervous system disease.
