Comparison of Campylobacter jejuni lipooligosaccharide biosynthesis loci from a variety of sources.

ABSTRACT: Campylobacter jejuni strains exhibit significant variation in the genetic content of the lipooligosaccharide (LOS) biosynthesis loci with concomitant differences in LOS structure. The C. jejuni LOS loci have been grouped into six classes based on gene content and organization. Utilizing PCR amplifications of genes from these loci, we were able to classify a majority (80%) of the LOS biosynthesis loci from 123 strains of C. jejuni that included 39 of the Penner serotype reference strains. We found that a particular LOS class was not always associated with a specific Penner serotype, and 14 of 16 Guillain-Barré syndrome-associated isolates tested in this study shared the same LOS class. The remaining isolates that could not be classified were often distinguishable from each other based on th
