Resumen
Campylobacter jejuni causes campylobacteriosis, a bacterial gastroenteritis with high
incidence worldwide. Moreover, C. jejuni infection can trigger the polyneuropathic disorder
denominated Guillain-Barré syndrome (GBS). The C. jejuni strains that can elicit GBS carry either
wlaN or cgtB, coding both genes for a β-1,3-galactosyltransferase enzyme that is required for the
production of sialylated lipooligosaccharide (LOSSIAL). We described a differential prevalence of the
genes wlaN and cgtB in C. jejuni isolates from three different ecological niches: humans, broiler
chickens, and wild birds. The distribution of both genes, which is similar between broiler chicken
and human isolates and distinct when compared to the wild bird isolates, suggests a host-dependent
distribution. Moreover, the prevalence of the wlaN and cgtB genes seems to be restricted to some
clonal complexes. Gene sequencing identified the presence of new variants of the G- homopolymeric
tract within the wlaN gene. Furthermore, we detected two variants of a G rich region within the cgtB
gene, suggesting that, similarly to wlaN, the G-tract in the cgtB gene mediates the phase variation
control of cgtB expression. Caco-2 cell invasion assays indicate that there is no evident correlation
between the production of LOSSIAL and the ability to invade eukaryotic cells.
