We reported a 28-year-old woman who had Guillain-Barré syndrome (GBS). Eight days after fever up and abdominal pain, she had weakness and dysesthesia of both hands and feet. Campylobacter jejuni (C. jejuni) was isolated from her stool culture without diarrhea. IgG anti-GM1 antibody was detected in her serum. Nerve conduction studies revealed a predominantly axonal neuropathy. After intravenous immunoglobulin therapy, her symptoms promptly improved. Penner 19 of C. jejuni was isolated more frequently from the GBS patients than from sporadic enteritis patients. In this case, C. jejuni with the serogroup Penner A was isolated. The serogroup is detected rarely in GBS.
