Emerging Sialylated Class R Lipooligosaccharides in Campylobacter jejuni from Seagulls Has the Potential to Trigger Guillain-Barré Syndrome - Yunnan Province, China, 2018-2023.

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.
Competing Interests: No conflicts of interest.
