Ke. Dingle et al., Sequence typing confirms that Campylobacter jejuni strains associated withGuillain-Barre and Miller-Fisher syndromes are of diverse genetic lineage,serotype, and flagella type, J CLIN MICR, 39(9), 2001, pp. 3346-3349
Guillain-Barre syndrome (GBS) and Miller-Fisher syndrome (MFS) are correlat
ed with prior infection by Campylobacter jejuni in up to 40% of cases. Nucl
eotide sequence-based typing of 25 C. jejuni isolates associated with neuro
pathy permitted robust comparisons with equivalent data from approximately
800 C. jejuni isolates not associated with neuropathy. A total of 13 geneti
c lineages and 20 flaA short variable region nucleotide sequences were pres
ent among the 25 isolates. A minority of isolates (4 of 25) had the flaA sh
ort variable region nucleotide sequences that were previously proposed as a
marker for GBS-associated isolates. These 4 isolates probably represented
the Penner serotype 19 lineage, which has been proposed to have an associat
ion with GBS.
