Guillain-Barré syndrome associated Campylobacter jejuni serotype Penner 2: A case report

: We described a 15-year-old male who had Guillain-Barre syndrome(GBS). Nine days after watery diarrhea, the patient developed pain and weakness of foot muscles. On admission, the nerve conduction studies revealed peripheral neuropathy with axonal degeneration and demyelination. Campylobacter jejuni(C. jejuni) with serotype of Lior 4, Penner 2 was isolated from his stool culture. IgM anti-GM 1 antibody and other various anti-ganglioside antibodies were detected in his serum. After receiving plasma exchange and intravenous immunoglobulin therapy, he was able to walk without assistance. In general, C. jejuni with the serotype Penner 19 has been isolated from many GBS patients. In this patient, C. jejuni with the serotype of Penner 2 was isolated. The serotype is detected commonly in Miller Fisher syndrome.
