What Bacteria is Associated with Guillain-Barré syndrome (GBS)?
Campylobacter jejuni has been shown by several studies to be strongly associated with Guillain-Barré syndrome (GBS). In the landmark Kuroki et al. studyC. jejuni was found in approximately 30% of GBS patients compared with only 1.2% of a healthy control population. Several studies have demonstrated similar findings. Another notable cause is cytomegalovirus (CMV).
