Campylobacter jejuni strains from patients with guillain-barré syndrome belong mostly to penner serogrpup 19 and contain β-N-acetylglucosamine residues



Campylobactor jejuni was isolacted from stool cultures from 14(30%) of 46 partients with Guillain-Barré syndrome and from 6(1.2%) of healthy persons, and the difference was highly significant (P<0.0001). In addition, serological evidence of recent. C. Jejuni infection. Ten of 12(83%) isolated from partients with Guillain-Barré syndrome belonged to Penner serogroup 19, which is a rare serogroup in sporadic patients with C. Jejuni enterties. In the lection typing stude, all serogroup 19 strains from patients with Guillain-Barré syndrome patients with Guillain-Barré syndrome were shown to contain terminal b̃-N-acetylglucosamine residues on their cell surface, bur serogroup 19 strains from patients with enteritis were not.
