  Seven patients with Miller Fisher syndrome (MFS), six in the acute phase and one in the recovery phase, were investigated for serum antibodies against gangliosides and purified lipopolysaccharides (LPS) from different strains of Campylobacter jejuni, including the MFS-associated serotypes O:2 and O:23. Immunoglobulin G antibodies against gangliosides GT1a and GQ1b were found in five of six patients in the acute phase of disease. Three of these patients also displayed antibodies to ganglioside GD2, a finding not previously reported for MFS. All anti-GT1a- and anti-GQ1b-seropositive patients showed antibody binding to C. jejuni LPS, predominantly to O:2 and O:23 LPS. Antibody cross-reactivity between gangliosides GT1a and GQ1b and O:2 and O:23 LPS was demonstrated by adsorption studies. This cross-reactivity between gangliosides and C.jejuni LPS, which is obviously due to oligosaccharide homologies, may be an important pathogenetic factor in the development of MFS after C. jejuni infection

  Three patients who had diarrhea prior to the development of Miller Fisher syndrome are presented. Campylobacter jejuni was isolated from stool specimens from all patients. High titers of anti-GQ1b IgG antibodies were demonstrated in the serum of these patients by enzyme-linked immunosorbent assay and thin-layer chromatography overlay. In enzyme-linked immunosorbent assay inhibition studies the anti-GQ1b IgG antibodies bound specifically to whole bacteria of the Miller Fisher syndrome-associated C. jejuni strains. The presence of anti-GQ1b IgG binding epitopes on the surface of the C. jejuni from the patients was not exclusively associated with a specific Penner serotype. It is suggested that anti-GQ1b antibodies are formed during the initial infection that elicits Miller Fisher syndrome. The cross-reactivity of anti-GQ1b IgG antibodies with surface epitopes on Miller Fisher syndrome-associated C. jejuni strains supports the hypothesis of molecular mimicry between bacteria and neural tissue.
