Campylobacter jejuni infections are thought to induce
antiganglioside antibodies in patients with Guillain-Barré
syndrome (GBS) and Miller Fisher syndrome (MFS) by molecular mimicry
between C. jejuni lipopolysaccharides (LPS) and
gangliosides. We used purified LPS fractions from five
Campylobacter strains to induce antiganglioside responses
in rabbits. The animals that received injections with LPS from
GBS-associated strains developed anti-GM1 and
anti-GA1 antibodies. Animals injected with LPS from one
MFS-related C. jejuni strain produced anti-GQ1b
antibodies. Rabbits that were injected with Penner O:3 LPS had a strong
anti-LPS response, but no antiganglioside reactivity was observed. The
antiganglioside specificity in the rabbits reflected the specificity in
the patients from whom the strains were isolated. In conclusion, our
results indicate that an immune response against GBS- and
MFS-associated C. jejuni LPS results in antiganglioside
antibodies. These results provide strong support for molecular mimicry
as a mechanism in the induction of antiganglioside antibodies following infections.
