What enteric infection has been associated with GBS?
Respiratory and intestinal infections, vaccinations, and other immunologic influences have been associated with GBS, an autoimmune demyelinating or axonal peripheral neuropathy usually manifesting as progressive ascending weakness and paralysis. Campylobacter jejuni infection is the most common infection associated with GBS and is usually of an axonal subtype . Molecular mimicry of the bacterial lipopolysaccharide and ganglioside moieties on peripheral nerves appears to be a dominant mechanism. In the developing world, it is estimated that one third of all cases of acute flaccid paralysis are GBS caused by Campylobacter.
