toxin production by campylobacter spp.	of all the virulence factors that were proposed for campylobacter jejuni and related species to cause disease in humans, the discovery of toxin production was the most promising but led to a rather confusing and even disappointing stream of data. the discussion of whether proteinaceous exotoxins are relevant in disease remains open. one important reason for this lack of consensus is the anecdotal nature of the literature reports. to provide a basis for an unbiased opinion, this review compiles a ...	1997	9227862
molecular discrimination between campylobacter jejuni, campylobacter coli, campylobacter lari and campylobacter upsaliensis by polymerase chain reaction based on a novel putative gtpase gene.	polymerase chain reaction (pcr) mediated dna fingerprinting has resulted in the identification of a novel campylobacter jejuni gene, encoding a gtpase protein. the gene, consisting of 383 amino acids contained semi-conserved gtp-binding sites (designated g-1 to g-4), that are characteristic for members of the gtpase protein superfamily. remarkably, this gene from c. jejuni appears to encode a member of a novel family of gtp-binding proteins, containing two separate putative gtp-binding domains, ...	1997	9232616
differentiation of campylobacter jejuni and campylobacter coli by polymerase chain reaction.	a multiplex pcr assay was developed using two primer sets for the identification and differentiation of campylobacter coli and campylobacter jejuni. primer set i amplifies a 460-bp fragment present in c. coli and c. jejuni. set ii amplifies a 160-bp target unique to c. jejuni. when the assay was performed on reference strains, amplification of c. coli yielded only the 460-bp fragment. amplification of c. jejuni generated both the 160- and 460-bp fragments. campylobacter field strains (n = 85) is ...	1997	9232618
evaluation of the nasba nucleic acid amplification system for assessment of the viability of campylobacter jejuni.	although nasba uses rna as a target molecule for amplification, the nucleic acid amplification system cannot be used for differentiating viable and non-viable c. jejuni. it was shown that 16s rrna, or the defined sequence within the 16s rrna enclosed by the primer set applied, is fairly stable and resistant to heating at 100 degrees c. false-positive results can occur in case of direct nasba detection of c. jejuni in foods. these false positive results due to amplification of rna from dead cells ...	1997	9237117

reactivity of serum igg anti-gm1 ganglioside antibodies with the lipopolysaccharide fractions of campylobacter jejuni isolates from patients with guillain-barre syndrome (gbs).	campylobacter jejuni (cj) enteritis is the most frequently recognised infection preceding guillain-barre syndrome (gbs) and this combination is commonly associated with anti-gm1 ganglioside (anti-gm1) antibodies. we have examined the hypothesis that the anti-gm1 antibodies represent an immune response against the cj lipopolysaccharide (lps). we prepared the lps fraction from 8 isolates of cj, 3 from gbs patients with acute inflammatory demyelinating polyradiculoneuropathy (aidp), 3 from patients ...	1997	9058756
immunological investigation of chronic inflammatory demyelinating polyradiculoneuropathy.	in order to investigate the hypothesis that chronic inflammatory demyelinating polyradiculoneuropathy (cidp) is an autoimmune disease related to the acute inflammatory form of guillain-barre syndrome (gbs), we studied 40 patients, 40 age and sex matched controls with other forms of peripheral neuropathy (onp) and 37 controls from the same family or household (fc). we sought antibodies to gangliosides gm1 and lm1 by enzyme linked immunoassay (elisa) confirmed by immuno-overlay. only 6 (15%) cidp ...	1997	9058768
lineages within campylobacter jejuni defined by numerical analysis of pulsed-field gel electrophoretic dna profiles.	forty-seven penner heat-stable (hs) serotype reference strains for campylobacter jejuni and 47 serologically non-typable strains were examined by pulsed field gel electrophoresis (pfge) dna restriction analysis. the smai and kpni digest profiles were compared by numerical analysis. most strains grouped differently in the two analyses but strain lineages were inferred where the two agreed. genetic relationships between reference strains in the cross-reacting hs4 complex were examined. three clona ...	1997	9060876
motor nerve terminal degeneration provides a potential mechanism for rapid recovery in acute motor axonal neuropathy after campylobacter infection.	we investigated the possible mechanisms of paralysis and recovery in a patient with the acute motor axonal neuropathy (aman) pattern of the guillain-barré syndrome. the aman pattern of gbs is characterized clinically by acute paralysis without sensory involvement and electrodiagnostically by low compound motor action potential amplitudes, suggesting axonal damage, without evidence of demyelination. many aman patients have serologic or culture evidence of recent campylobacter jejuni infection. pa ...	1997	9065554
hydrophobic characterization of thermophilic campylobacter species and adhesion to int 407 cell membranes and fibronectin.	cell surface hydrophobicity of campylobacter jejuni, c. coli, c. lari and c. upsaliensis was tested by hydrophobic interaction chromatography on octylsepharose cl-4b. the hydrophobicity was influenced by cultivation mode, presence or absence of intact lipopolysaccharide (lps) and outer membrane protein structures. species-specific differences of hydrophobic characteristics were not detected. bacteria grown in fluid medium exhibited a high degree of hydrophobicity. agar-grown bacteria showed hydr ...	1997	9075218
chey-mediated modulation of campylobacter jejuni virulence.	four motile, non-adherent and non-invasive mutants of campylobacter jejuni 81-176 generated by a site-specific insertional mutagenesis scheme were characterized at the molecular level and all contained a duplication of the same region of the chromosome. when this region was cloned from wild-type 81-176 and transferred into 81-176 on a shuttle plasmid, the same non-invasive phenotype as the original mutants was observed, suggesting that the region contained a repressor of adherence and invasion. ...	1997	9076738

preferential interaction of the his pause rna hairpin with rna polymerase beta subunit residues 904-950 correlates with strong transcriptional pausing.	rna secondary structures (hairpins) that form as the nascent rna emerges from rna polymerase are important components of many signals that regulate transcription, including some pause sites, all rho-independent terminators, and some antiterminators. at the his leader pause site, a 5-bp-stem, 8-nt-loop pause rna hairpin forms 11 nt from the rna 3' end and stabilizes a transcription complex conformation slow to react with ntp substrate. this stabilization appears to depend at least in part on an i ...	1997	9237994
carbon load in aquatic ecosystems affects the diversity and biomass of water biofilm consortia and the persistence of the pathogen campylobacter jejuni within them.	the influence of carbon load on autochthonous water microflora population distribution and diversity, and on the persistence of campylobacter jejuni, was examined with a two-stage aquatic biofilm model. serine was chosen since it is a carbon source utilised by c. jejuni and concentrations were chosen to reflect upper limits of amino acid load reported in surface water. the total viable count of the autochthonous biofilm microflora increased with increasing serine concentration (10-fold and 20-fo ...	1998	21182705
serological evidence for infection with campylobacter jejuni/coli in patients with multifocal motor neuropathy.	campylobacter jejuni/coli (cjc) infection has been implicated in the immunopathogenesis of guillain-barré syndrome (gbs), acute motor axonal neuropathy (aman), and miller fisher syndrome (mfs). however, its role in chronic immune mediated neuropathies such as multifocal motor neuropathy (mmn) or chronic inflammatory demyelinating polyradiculoneuropathy (cidp) is less clear. anti-ganglioside antibodies are associated with chronic motor neuropathies such as mmn and igm anti-gm1, and igm anti-asial ...	1998	18644284
incidental finding of myxobolus spores (protozoa: myxozoa) in stool samples from patients with gastrointestinal symptoms.	myxozoan spores were detected in fecal samples from three patients presenting with abdominal pain and/or diarrhea. the spores were identical to those of myxobolus plectroplites, a previously described pathogen from the freshwater fish plectroplites ambiguus. all patients had recently eaten fish caught from local waters, and frozen fillets of such fish were found to be infected with m. plectroplites cysts. the passage of spores unchanged through the alimentary tract suggests they were incidental ...	1998	9817910
