A deep-rough mutant of campylobacter jejuni 81-176 is noninvasive for intestinal epithelial cells
(American Society for Microbiology, 2004-03-23)A waaF mutant of Campylobacter jejuni 81-176 showed decreased invasion of INT407 cells in vitro and increased sensitivity to some antibiotics compared to what was seen with the wild-type strain. -
Anti‐ganglioside antibody induction by swine (a/nj/1976/h1n1) and other influenza vaccines: insights into vaccine‐associated guillain‐barré syndrome
(Oxford University Press (OUP), 2008-07-15)Background. Receipt of an A/NJ/1976/H1N1 "swine flu" vaccine in 1976, unlike receipt of influenza vaccines used in subsequent years, was strongly associated with the development of the neurologic disorder ... -
Campylobacter jejuni from patients with guillain-barre syndrome preferentially expresses a gd1a-like epitope
(American Society for Microbiology, 2002-09-01)GM(1)- and GD(1a)-like ganglioside mimicry in Campylobacter jejuni lipooligosaccharide (LOS) is considered to be involved in the pathogenesis of Campylobacter-induced Guillain-Barre syndrome (GBS). Compared with ... -
Different effectiveness of helicobacter pylori lipopolysaccharides with or without lewisxy determinants in stimulating the secretion of proinflammatory cytokines il-8 and tnf-α by peripheral blood mononuclear leukocytes
(Termedia Sp. z.o.o., 2011-01-01)Introduction: Helicobacter pylori is an aetiological agent of chronic gastritis, gastric and duodenal ulcers, and gastric cancers. It is suggested that H. pylori must have undergone evolutionary changes that enable the ... -
Expression of surfactant protein d in the human gastric mucosa and during helicobacter pylori infection
(American Society for Microbiology, 2002-03-01)Helicobacter pylori establishes persistent infection of gastric mucosa with diverse clinical outcomes. The innate immune molecule surfactant protein D (SP-D) binds selectively to microorganisms, inducing aggregation and ... -
In vivo phase variation and serologic response to lipooligosaccharide of campylobacter jejuni in experimental human infection
(American Society for Microbiology, 2004-01-23)Some Campylobacter jejuni strains which exhibit mimicry of gangliosides in their lipooligosaccharides (LOSs) are associated with development of Guillain-Barre syndrome, which complicates the selection of a suitable C. ... -
Influence of medium composition on the growth and antigen expression of helicobacter pylori
(Wiley-Blackwell, 1997-06-01)An evaluation of the ability of various solid and liquid media to support both growth and antigen expression, particularly lipopolysaccharide (LPS) expression, by Helicobacter pylori culture collection strains and clinical ... -
Lectin typing of campylobacter concisus
(American Society for Microbiology, 2002-02-01)A total of 44 clinical isolates and the type strain of the putative pathogen Campylobacter concisus were grouped based on their reactions with plant lectins. The optimized lectin typing system used C. concisus strains ... -
Molecular origin of two polysaccharides ofcampylobacter jejuni81116
(Oxford University Press (OUP), 2006-10-01)The nature of the polysaccharide molecules of the human enteric pathogen Campylobacter jejuni has been the subject of debate. Previously, C. jejuni 81116 was shown to contain two different polysaccharides, one acidic ... -
Novel myelin penta- and hexa-acetyl-galactosyl-ceramides: structural characterization and immunoreactivity in cerebrospinal fluid
(American Society for Biochemistry & Molecular Biology (ASBMB), 2010-02-12)Fast migrating cerebrosides (FMC) are derivatives of galactosylceramide (GalCer). The structures of the most hydrophobic FMC-5, FMC-6, and FMC-7 were determined by electrospray ionization linear ion-trap mass spectrometry ... -
Phase variation of campylobacter jejuni 81-176 lipooligosaccharide affects ganglioside mimicry and invasiveness in vitro
(American Society for Microbiology, 2002-02-01)The outer cores of the lipooligosaccharides (LOS) of many strains of Campylobacter jejuni mimic human gangliosides in structure. A population of cells of C.jejuni strain 81-176 produced a mixture of LOS cores which consisted ... -
Phenotypic variation of helicobacter pylori isolates from geographically distinct regions detected by lectin typing
(American Society for Microbiology, 2002-01-01)A total of 309 Helicobacter pylori isolates from 18 different countries were analyzed with a previously developed lectin typing system. The system was developed by using a proteolytic pretreatment to enhance the carbohydrate ... -
Relationship of anti-lewis x and anti-lewis y antibodies in serum samples from gastric cancer and chronic gastritis patients to helicobacter pylori-mediated autoimmunity
(American Society for Microbiology, 2001-08-01)Lewis (Le) antigens have been implicated in the pathogenesis of atrophic gastritis and gastric cancer in the setting of Helicobacter pylori infection, and H. pylori-induced anti-Le antibodies have been described that ... -
Sialylation of lipooligosaccharide cores affects immunogenicity and serum resistance of campylobacter jejuni
(American Society for Microbiology, 2000-12-01)Three genes involved in biosynthesis of the lipooligosaccharide (LOS) core of Campylobacter jejuni MSC57360, the type strain of the HS:1 seretype, whose structure mimics GM(2) ganglioside, have been cloned and characterized. ...
