Abstract
A 37-year-old man presented with acute dizziness, nausea, headache and fever. Later on, he developed diplopia, swallowing difficulties, numbness and ataxia. MRI on day 6 showed hypo-intense, contrast-enhancing lesions on TI-weighted scans in the brainstem and cerebellum. Cerebrospinal fluid (CSF) findings on day 6 included pleiocytosis, a mildly-elevated protein level and mildly-decreased glucose level. CSF and blood cultures were initially negative for both bacteria and viruses. Acute disseminated encephalomyelitis (ADEM) was suspected and dexamethasone therapy was started. On day 26, a blood culture was positive for Listeria monocytogenes. The diagnosis 'Listeria rhombencephalitis' was made and the patient was treated with amoxicillin. This resulted in good recovery. In patients with a subacute onset of progressive cranial nerve dysfunction, ataxia, CSF pleiocytosis, and MRI lesions in the brainstem and cerebellum, Listeria rhombencephalitis should be considered. Early diagnosis and treatment improve the prognosis.

Abstract
Molecular mimicry of Campylobacter jejuni lipooligosaccharides (LOS) by gangliosides in peripheral nerve tissue probably triggers the Guillain-Barré syndrome due to the induction of cross-reactive antibodies. PCR-restriction fragment length polymorphism analysis of C. jejuni genes involved in the biosynthesis of LOS demonstrated that specific genes were associated with the expression of ganglioside mimics and the development of neuropathy.

Abstract
Molecular mimicry between lipooligosaccharides (LOS) of Campylobacter jejuni and gangliosides in peripheral nerves plays a crucial role in the pathogenesis of C. jejuni-related Guillain-Barré syndrome (GBS). We have analyzed the LOS outer core structures of 26 C. jejuni strains associated with GBS and its variant, Miller Fisher syndrome (MFS), by capillary electrophoresis coupled with electrospray ionization mass spectrometry. Sixteen out of 22 (73%) GBS-associated and all 4 (100%) MFS-associated strains expressed LOS with ganglioside mimics. GM1a was the most prevalent ganglioside mimic in GBS-associated strains (10/22, 45%), and in eight of these strains, GM1a was found in combination with GD1a mimics. All seven strains isolated from patients with ophthalmoplegia (GBS or MFS) expressed disialylated (GD3 or GD1c) mimics. Three out of 22 GBS-associated strains (14%) did not express sialylated ganglioside mimics because their LOS locus lacked the genes necessary for sialylation. Three other strains (14%) did not express ganglioside mimics because of frameshift mutations in either the cstII sialyltransferase gene or the cgtB galactosyltransferase gene. It is not possible to determine if these mutations were already present during C. jejuni infection. This is the first report in which mass spectrometry combined with DNA sequence data were used to infer the LOS outer core structures of a large number of neuropathy-associated C. jejuni strains. We conclude that molecular mimicry between gangliosides and C. jejuni LOS is the presumable pathogenic mechanism in most cases of C. jejuni-related GBS. However, our findings suggest that in some cases, other mechanisms may play a role. Further examination of the disease etiology in these patients is mandatory.

Abstract
Campylobacter jejuni is the predominant cause of antecedent infection in Guillain-Barré syndrome (GBS) or Miller Fisher syndrome (MFS). C. jejuni probably triggers GBS or MFS through molecular mimicry between bacterial sialylated lipo-oligosaccharides (LOS) and gangliosides in peripheral nerve tissue. We investigated whether co-infections with multiple C. jejuni strains occur in GBS or MFS patients and we further characterized these strains. PFGE analysis of 83 C. jejuni isolates from single primary colonies from stool cultures of 13 patients with GBS or MFS revealed co-infection with two different strains in one patient (8%). We showed that only strain GB5.1 contained an LOS biosynthesis gene locus that is associated with neuropathy. The patient serum strongly reacted with the LOS of strain GB5.1 and not with the LOS of strain GB5.2. Mass spectrometry revealed that both strains expressed a non-sialylated outer core structure in their LOS. The patient serum contained anti-asialo-GM2 antibodies that cross-reacted with the LOS of strain GB5.1. This study demonstrates that co-infection with multiple C. jejuni strains occurs in GBS patients. Consequently, not all C. jejuni strains isolated from the faeces of a GBS patient are involved in the pathogenesis of GBS per se. Furthermore, this is the first report in which cross-reactivity of antibodies to asialo-GM2 and to the LOS of a C. jejuni strain from a GBS patient has been demonstrated. This finding suggests that molecular mimicry with non-sialylated structures may also be involved in the pathogenesis of GBS.

Abstract
The Inflammatory Neuropathy and Treatment (INCAT) group developed a standardized ELISA method for the detection of serum anti-GM1 antibodies. The diagnostic value of anti-GM1 antibodies determined by this method has not yet been established in large groups of patients. We assessed the reproducibility, sources of variation, optimal cut-off values and evaluated the diagnostic relevance of the INCAT-ELISA in various groups of patients and controls (N=1232). The coefficient of variance was 11.2% for IgM and 3.8% for IgG. High IgG titers were only found in Guillain-Barré syndrome (GBS) and other inflammatory polyneuropathies. High IgM titers were associated with GBS and multifocal motor neuropathy. Low IgM titers had no additional diagnostic value. The INCAT-ELISA is a reliable test with additional diagnostic value in specific clinical situations.

Abstract
Molecular mimicry of Campylobacter jejuni lipo-oligosaccharides (LOS) with gangliosides in nervous tissue is considered to induce cross-reactive antibodies that lead to Guillain-Barre syndrome (GBS), an acute polyneuropathy. To determine whether specific bacterial genes are crucial for the biosynthesis of ganglioside-like structures and the induction of anti-ganglioside antibodies, we characterized the C. jejuni LOS biosynthesis gene locus in GBS-associated and control strains. We demonstrated that specific types of the LOS biosynthesis gene locus are associated with GBS and with the expression of ganglioside-mimicking structures. Campylobacter knockout mutants of 2 potential GBS marker genes, both involved in LOS sialylation, expressed truncated LOS structures without sialic acid, showed reduced reactivity with GBS patient serum, and failed to induce an anti-ganglioside antibody response in mice. We demonstrate, for the first time, to our knowledge, that specific bacterial genes are crucial for the induction of anti-ganglioside antibodies.

Abstract
Molecular mimicry between microbial antigens and host tissue forms an attractive hypothetical mechanism for the triggering of autoimmune disease by preceding infections. Recent crucial reviews state that molecular mimicry, as the causative mechanism, remains unproven for any human autoimmune disease. However, the peripheral neuropathy Guillain-Barré syndrome (GBS) is largely overseen in this debate. Based on recent evidence, we argue that GBS should be considered as an excellent paradigm and an attractive model for elucidation of both host and microbial aspects of molecular mimicry.

Abstract
A steady increase in the incidence of Guillain-Barré syndrome (GBS) with a seasonal preponderance, almost exclusively related to Campylobacter jejuni, and a rise in the incidence of laboratory-confirmed Campylobacter enteritis have been reported from Curaçao, Netherlands Antilles. We therefore investigated possible risk factors associated with diarrhea due to epidemic C. jejuni. Typing by pulsed-field gel electrophoresis identified four epidemic clones which accounted for almost 60% of the infections. One hundred six cases were included in a case-control study. Infections with epidemic clones were more frequently observed in specific districts in Willemstad, the capital of Curaçao. One of these clones caused infections during the rainy season only and was associated with the presence of a deep well around the house. Two out of three GBS-related C. jejuni isolates belonged to an epidemic clone. The observations presented point toward water as a possible source of Campylobacter infections.

Abstract
Campylobacter jejuni GB11, a strain isolated from a patient with Guillain-Barré syndrome, has been shown to be genetically closely related to the completely sequenced strain C. jejuni NCTC 11168 by various molecular typing and serotyping methods. However, we observed that the lipooligosaccharide (LOS) biosynthesis genes strongly diverged between GB11 and NCTC 11168. We sequenced the LOS biosynthesis locus of GB11 and found that it was nearly identical to the class A LOS locus from the C. jejuni HS:19 Penner serotype strain (ATCC 43446). Analysis of the DNA sequencing data showed that a horizontal exchange event involving at least 14.26 kb had occurred in the LOS biosynthesis locus of GB11 between galE (Cj1131c in NCTC 11168) and gmhA (Cj1149 in NCTC 11168). Mass spectrometry of the GB11 LOS showed that GB11 expressed an LOS outer core that mimicked the carbohydrate portion of the gangliosides GM1a and GD1a, similar to C. jejuni ATCC 43446. The serum from the GB11-infected patient was shown to react with the LOS from both GB11 and ATCC 43446 but not with that from NCTC 11168. These data indicate that the antiganglioside response in the GB11-infected patient was raised against the structures synthesized by the acquired class A LOS locus.

Abstract
To seek evidence for a role of molecular mimicry in the induction of Guillain-Barré syndrome (GBS), the authors studied Campylobacter jejuni-reactive T lymphocytes in patients with GBS. In contrast to controls, gammadelta T cells of patients with GBS with antecedent C jejuni infections failed to respond to C jejuni. Supplementing cell cultures with the cytokines interleukin-2 or interleukin-15 resulted in restoration of the gammadelta T cell proliferative response. Gammadelta T cell non-responsiveness may lead to defective regulation of antibody production, and in this way an (auto)immune response against ganglioside-like epitopes on peripheral nerve may cause GBS.

Abstract
A 68 year old woman developed oculomotor paresis shortly after metastatic progression of her melanoma was discovered. She was then immunised with the tumour antigen MAGE-3 in combination with an immunological adjuvant. During immunisation her symptoms worsened and she developed severe, predominantly proximal axonal motor neuropathy and became bedridden. IgM antibodies against gangliosides GM2, GD3, and GQ1b were detected in serum obtained two weeks before and nine weeks after the onset of symptoms. Immunohistochemically, the patient's IgM reacted with the tumour and co-localised with GQ1b. She improved neurologically following steroid treatment and became ambulatory.

Abstract
Campylobacter jejuni is currently the prime cause of food-borne bacterial gastro-enteritis. An important complication of C. jejuni enteritis is Guillain-Barré syndrome (GBS), an immune-mediated disorder of peripheral nerve tissue. Because little is known about T cell reactivity to C. jejuni, we have analyzed the in vitro immune response of normal individuals against five isolates of C. jejuni representing five different serotypes. We found a preferential expansion of peripheral blood gammadelta T cells after exposure to crude sonicates of all five C. jejuni serotypes. Expansion of gammadelta T cells was dependent on the presence of CD4+/alphabeta+ T cells in the cultures or addition of exogenous IL-2 or IL-15. C. jejuni stimulation was mediated via the TCR and appeared to be induced by a non-proteinaceous bacterial antigen, most likely of phosphoantigenic origin.

Abstract
Anti-galactocerebroside (GalC) antibodies are reported to be present in GBS patients with preceding Mycoplasma pneumoniae (MP) infection. We investigated the presence of anti-GalC reactivity in serum of a large group of GBS patients using ELISA and compared this with healthy controls and individuals with an uncomplicated MP infection. Anti-GalC antibody reactivity was present in 12% of the GBS patients. Furthermore, anti-GalC antibodies were associated with MP infections, a relatively mild form of the disease and demyelinating features. Anti-GalC antibodies cross-reacted with MP antigen. In conclusion, anti-GalC antibodies in GBS patients may be induced by molecular mimicry with MP.

Abstract
The core oligosaccharides of Campylobacter jejuni lipopolysaccharides (LPS) display molecular mimicry with gangliosides. Cross-reactive anti-LPS-antiganglioside antibodies have been implicated to show a crucial role in the pathogenesis of the Guillain-Barré and Miller Fisher syndrome. The specificity of the antiganglioside response is thought to depend on the oligosaccharide structure of the ganglioside mimic. To test this hypothesis and to investigate the potential of LPS from Campylobacter strains from enteritis patients to induce an antiganglioside response, we immunized rabbits with purified LPS from eight Campylobacter jejuni reference strains with biochemically well-defined distinct ganglioside mimics and determined the presence of antiganglioside antibodies. All rabbits produced immunoglobulin G (IgM) and IgG anti-LPS antibodies, and the specificity of the cross-reactive antiganglioside response indeed corresponded with the biochemically defined mimic. Most rabbits also had antibody reactivity against additional gangliosides, and there were slight differences in the fine specificity of the antibody response between rabbits that had been immunized with LPS from the same Campylobacter strain. High anti-LPS and antiganglioside titers persisted over a 10-month period. In conclusion, the structure of the LPS only partly determines the antiganglioside specificity. Other strain-specific as well as host-related factors influence the induction and fine-specificity of the cross-reactive anti-LPS-antiganglioside response.

Abstract
Anti-GQ1b antibodies are associated with the Miller Fisher syndrome (MFS), a variant of the Guillain-Barré syndrome (GBS). In the ex vivo mouse diaphragm, anti-GQ1b-positive MFS serum induces muscle fiber twitching, a temporary dramatic increase of spontaneous quantal acetylcholine release, and transmission blockade at neuromuscular junctions (NMJs). These effects resemble those of alpha-latrotoxin (alpha-LTx) and are induced by antibody-mediated activation of complement. We developed an assay for detection of the alpha-LTx-like effect, using muscle fiber twitching as indicator. We tested 89 serum samples from GBS, MFS, and control subjects, and studied correlations with clinical signs, anti-ganglioside antibodies, micro-electrode physiology, and complement deposition at NMJs. Twitching was observed with 76% of the MFS and 10% of the GBS samples. It was associated with ophthalmoplegia and anti-GQ1b antibodies in patients, and with increased spontaneous acetylcholine release and C3c-deposition at mouse NMJs. This study strongly suggests that antibodies to GQ1b (with cross-reactivity to related gangliosides) are responsible for the alpha-LTx-like activity. The twitching assay is an efficient test for detection of this effect, and allows for screening of large numbers of samples and modifying drugs.

Abstract
Ganglioside mimicry in the lipopolysaccharide (LPS) fraction of Campylobacter jejuni isolated from Guillain-Barré syndrome (GBS) and Miller Fisher syndrome (MFS) patients was compared with isolates from patients with an uncomplicated enteritis. The antibody response to C. jejuni LPS and gangliosides in neuropathy patients and controls was compared as well. LPS from GBS and MFS-associated isolates more frequently contained ganglioside-like epitopes compared to control isolates. Almost all neuropathy patients showed a strong antibody response against LPS and multiple gangliosides in contrast to enteritis patients. Isolates from GBS patients more frequently had a GM1-like epitope than isolates from MFS patients. GQ1b-like epitopes were present in all MFS-associated isolates and was associated with anti-GQ1b antibody reactivity and the presence of oculomotor symptoms. These results demonstrate that the expression of ganglioside mimics is a risk factor for the development of post-Campylobacter neuropathy. This study provides additional evidence for the hypothesis that the LPS fraction determines the antiganglioside specificity and clinical features in post-Campylobacter neuropathy patients.

Abstract
OBJECTIVE Twenty-eight percent of patients with the Guillain-Barré syndrome remain able to walk unaided. Studying patients with the mild form of Guillain-Barré syndrome can further contribute to knowledge of the spectrum of the syndrome and explore whether this subgroup may need treatment with IV immunoglobulin. METHODS Patients fulfilling the National Institute of Neurologic and Communicative Disorders and Stroke criteria for Guillain--Barré syndrome were included in a nationwide survey over a 2-year period. Clinical characteristics and serum samples were collected prospectively. In addition, a questionnaire was completed concerning the course and outcome of the disease. RESULTS A total of 139 patients were included. Nineteen of the patients (14%) included were mildly affected, and 120 (86%) were severely affected. Infections with Epstein-Barr virus were found more frequently in mildly affected patients (p = 0.02). Antiganglioside antibodies were less frequently found in the mildly affected patients (p = 0.03). The degree of severity of the disease between mildly and severely affected patients was different on the day of admission (p < 0.01). Thereafter, the groups showed a remarkably similar rate of progression. Thirty-eight percent of mildly affected patients report problems in hand function and an inability to run at 3 and 6 months (all women, p = 0.02). CONCLUSION The difference in severity of Guillain--Barré syndrome seems to be determined in an early phase of the disease. Preceding infections and antiganglioside antibodies may influence the initial immune attack, determining the severity of the disease. The presence of residual signs in patients with mild disease may advocate the use of early treatment in mildly affected patients.

Abstract
Anti-ganglioside antibodies are consistently found in Guillain-Barré syndrome (GBS) patients from different geographical parts of the world. Several studies indicated differences in relative frequencies of anti-ganglioside reactivity and isotype distribution between GBS patients from Asia and from Europe. We investigated antibody reactivity against the gangliosides GM1, GM1b and GalNAc-GD1a in GBS patients from Japan and The Netherlands in two different laboratories. The proportion of GBS patients with anti-ganglioside antibodies did not differ between the two countries. GBS patients from The Netherlands more frequently had cross-reacting anti-GalNAc-GD1a/anti-GM1b antibodies and a stronger IgM anti-ganglioside response. Our findings indicate that geographical determined factors, dependent on either the host or the triggering infectious agent, determine the isotype distribution and fine specificity of anti-ganglioside antibodies in GBS patients.
