Abstract
WHAT IS ALREADY KNOWN ABOUT THIS TOPIC? Lipooligosaccharides from Campylobacter jejuni (C. jejuni) have a mimicry antigen structure with gangliosides, which explains the mechanism by which C. jejuni caused Guillain-Barré syndrome (GBS). WHAT IS ADDED BY THIS REPORT? All 12 C. jejuni strains with class R LOSs and specific serotypes were isolated from seagulls in south China. These emerging C. jejuni strains had ganglioside-mimicry antigen structures and possessed a high potential for triggering GBS. WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE? Sialylated lipooligosaccharides (LOS) class R with GBS-associated serotypes isolated from seagulls highlight the risk of induced GBS around coastal or lakeside areas.
