Background: Helicobacter saguini is a novel enterohepatic Helicobacter species isolated from captive cotton top tamarins with chronic colitis and colon cancer. Monoassociated H. saguini infection in gnotobiotic IL-10 −/− mice causes typhlocolitis and dysplasia; however, the virulent mechanisms of this species are unknown. Gamma-glutamyltranspeptidase (GGT) is an enzymatic virulence factor expressed by pathogenic Helicobacter and Campylobacter species that inhibits host cellular proliferation and promotes inflammatory-mediated gastrointestinal pathology. The aim of this study was to determine if H. saguini expresses an enzymatically active GGT homologue with virulence properties. Experimental procedures: Two putative GGT paralogs (HSGGT1 and HSGGT2) identified in the H. saguini genome were bioinformatically analysed to predict enzymatic functionality and virulence potential. An isogenic knockout mutant strain and purified recombinant protein of HSGGT1 were created to study enzymatic activity ...
Helicobacter species can colonise the mammalian gastrointestinal and hepatobiliary tract which usually results in a chronic infection coupled to an inflammatory host response. It is therefore not surprising that colonisation with Helicobacter species is linked with a range of inflammation associated gastrointestinal and hepatobiliary diseases.1 Recently, this range has been expanded, with an association of infection with enterohepatic Helicobacter species and the formation of cholesterol gallstones.2. In their study, Maurer and colleagues2 demonstrated that murine infection with the enterohepatic Helicobacter species H bilis and H hepaticus accelerated the formation of cholesterol gallstones in mice fed a lithogenic diet. Although the gallbladder mucosa in mice with gallstones displayed signs of inflammation, Helicobacter species were not cultured from the inflamed gallbladder or bile. Therefore, Maurer et al hypothesised that the chronic immune stimulation caused by Helicobacter species, rather ...
This study aimed to determine the prevalence of endoscopic and histological gastroduodenitis as well as helicobacter-like organisms in patients with end stage renal failure undergoing maintenance dialysis treatment. A total of 322 out of 422 patients in our dialysis programme underwent endoscopy and gastroduodenal biopsy specimens were taken from 260. Endoscopic gastroduodenitis occurred in 158 (49%). Histological gastritis occurred in the gastric body or antrum in 134 patients (52%) and duodenitis in 52 (21%). There was no correlation between endoscopic and histological gastritis in contrast to a significant correlation for duodenitis. Helicobacter-like organisms occurred in the body or antrum in 81 (31%). Their presence was associated with gastritis--in particular acute and acute on chronic gastritis rather than chronic gastritis. Patients with gastritis were significantly older than those without (p less than 0.001) and had lower basal and peak acid outputs.. ...

Previously, nine fecal isolates from wild birds and a domestic swine were identified as helicobacters by phenotypic characterization and reaction with a helicobacter genus-specific DNA probe. These isolates fell into three biotypes by analysis of phenotypic traits. To further characterize these isolates, full 16S rRNA sequences were determined for strains representing each biotype, and sequence comparison indicated that the strains represented three novel, phylogenetically defined Helicobacter species. Three 16S rRNA-based DNA probes were designed and used to identify the remaining strains. Probe reactivity divided the strains into the same three groups identified phenotypically. Six of the isolates represented a new species of the genus Helicobacter for which we propose the name Helicobacter pametensis sp. nov. The following phenotypic features distinguished H. pametensis from other Helicobacter and Campylobacter species: positive tests for oxidase, catalase, alkaline phosphatase, nitrate reduction,
The presence of Helicobacter spp. in the gastric mucosa is associated with inflammation and/or ulceration, and these bacteria are recognized as important pathogens in gastroduodenal disease. There is now mounting evidence that suggests that enterohepatic Helicobacter spp. may also be pathogenic for the host. Various other gastric Helicobacter spp. have now been isolated and characterized. Indeed, in rhesus and cynomolgus monkeys, these gastric Helicobacter spp. are indistinguishable from H. pylori, whereas pig-tailed macaques are colonized by H. nemestrinae. Several experimental models have been developed to study the inflammatory processes induced by the murine enterohepatic Helicobacter spp. As H. hepaticus, induces the proliferation of intestinal and hepatic host cells in vivo, it is unlikely that enterocytes or hepatocytes are the target cells for H. hepaticus cytolethal distending toxin (Cdt). Recently, studies in H. pylori SS1-infected mice demonstrated that Helicobacter infection models could
Helicobacter spp. are helical or curved, gram-negative bacteria. For culture, they need especially enriched culture media. The Helicobacter genus comprises at least 35 species. Some Helicobacter species colonise the gastric mucosa, while others colonise the intestine and liver of humans or animals. In humans, Helicobacter pylori is correlated with gastritis and stomach ulcers, but it is not normally relevant in animals. It is an anthroponotic disease - in other words, an infection of an animal with a human pathogen. Pathogenicity of Helicobacter spp. in animals has not yet completely been clarified. Helicobacter mustelae was detected in ferrets with gastritis and stomach ulcers, Helicobacter heilmanii was found in pigs with stomach ulcers. They also seem to be associated with gastritis, vomiting and inappetence in dogs and cats. Prevalence is very high, both in healthy as well as in infected animals. Hence, an infection does not always lead to the outbreak of the disease. It is likely that the ...

article{279c7ca3-4c9b-4e92-95e9-36ca7d4d1564, abstract = {In the 20 years since the discovery of Helicobacter pylori the number of formally described Helicobacter spp. has increased dramatically. The majority of species in the genus have been associated with some form of pathology. Similar to other Gram-negative bacteria, all helicobacters have lipopolysaccharides or endotoxins in the outer leaflet of their outer membrane which is an important modulator of the immune system. H. pylori endotoxin has a number of roles in the pathogenesis of the bacterium. Its relatively low biological and immunological activity and molecular mimicry may contribute to the chronic nature of infection through avoidance of host defence mechanisms and adhesion. In addition to endotoxins, various helicobacters also secrete distinct exotoxins capable of host cell damage. H. pylori has been shown to possess a cytotoxin capable of inducing vacuoles in epithelial cells termed vacuolating cytotoxin or VacA. Although VacA has ...
The International Committee of Systematic Bacteriology Subcommittee on the taxonomy of Campylobacter and related bacteria has agreed in principle on minimum requirements for the description of new species of the genus Helicobacter. These requirements include the recommendation that the description of a putative new species or subspecies be based on examination of at least five strains in order to provide a measure of phenotypic and genotypic variation. Recommendations for required phenotypic and molecular data are presented. The requirements are consistent with the polyphasic approach to bacterial systematics.

β-Lactams are often used to treat Helicobacter cinaedi infections; however, the mechanism underlying β-lactam resistance is unknown. In this study, we investigated β-lactam resistance in a H. cinaedi strain, MRY12-0051 (MIC of AMX and CRO: 32 and 128 μg/ml; obtained from human feces). Based on a comparative whole genome analysis of MRY12-0051 and the CRO-susceptible H. cinaedi strain MRY08-1234 (MIC of AMX and CRO: 1 and 4 μg/ml; obtained from human blood), we identified five mutations in genes encoding penicillin-binding proteins (PBPs), including two in pbpA, one in pbp2, and two in ftsI Transformation and penicillin-binding assays indicated that CRO resistance was mainly associated with mutations in pbpA; mutations in ftsI also led to increased resistance to AMX ...

Introduction. Helicobacter suis ( Helicobacter heilmannii type 1) commonly infects nonhuman primates but its clinical importance is in question. Aim. To characterize H. suis infection in a colony of rhesus macaques (Macaca mulatta) used in cognitive neuroscience research. Hypothesis/Gap Statement. Inquiries into the nature of Helicobacter suis in nonhuman primates are required to further define the organisms virulence and the experimental animals gastric microbiome. Methodology. Animals with and without clinical signs of vomiting and abdominal pain (n=5 and n=16, respectively) were evaluated by histology, culture, PCR amplification and sequencing, fluorescent in situ hybridization (FISH) and serology. Three of the five animals with clinical signs, an index case and two others, were evaluated before and after antimicrobial therapy. Results. The index animal had endoscopically visible ulcers and multifocal, moderate, chronic lymphoplasmacytic gastritis with intraglandular and luminal spiral bacteria.

CD4(+)CD25(+) regulatory T (T(R)) cells can inhibit a variety of autoimmune and inflammatory diseases, but the precise mechanisms by which they suppress immune responses in vivo remain unresolved. Here, we have used Helicobacter hepaticus infection of T cell-reconstituted recombination-activating gene (RAG)(-/-) mice as a model to study the ability of CD4(+)CD25(+) T(R) cells to inhibit bacterially triggered intestinal inflammation. H. hepaticus infection elicited both T cell-mediated and T cell-independent intestinal inflammation, both of which were inhibited by adoptively transferred CD4(+)CD25(+) T(R) cells. T cell-independent pathology was accompanied by activation of the innate immune system that was also inhibited by CD4(+)CD25(+) T(R) cells. Suppression of innate immune pathology was dependent on T cell-derived interleukin 10 and also on the production of transforming growth factor beta. Thus, CD4(+)CD25(+) T(R) cells do not only suppress adaptive T cell responses, but are also able to control
The existence of breed-specific intestinal diseases would suggest that there is an underlying genetic cause to each disease. However, many gastrointestinal (GI) diseases have an infectious aetiology, and suspected inherited diseases can be due to infection transmitted between relatives. In humans, for example, gastric Helicobacter infection most commonly follows infection from the mother, and can lead to a spectrum of disease raging from gastritis to ulcers, mucosal lymphoma and gastric carcinoma. Gastric carcinoma is the most common gastric neoplasm of dogs, and the marked over-representation of the disease in collies, especially Rough collies, suggests a genetic predisposition. However, passage of a pathogenic strain of Helicobacter from dam to pup as the initiating cause cannot be ruled out. For whilst the pathogenicity of Helicobacter in dogs and cats is debated, there is no doubt in veterinary dermatology that the transmission of Demodex from dam to pups occurs, and similar transmission of ...

Doctors-naturopathic or otherwise-practicing in the Northeast will tell you that Lyme disease is an epidemic illness affecting large parts of their practices. Fewer than fifty percent of people who acquire Lyme disease dont remember being bit by a tick and wont actually manifest the bulls-eye rash commonly associated with Lyme. These patients wont realize that theyve been infected by the spiral-shaped bacteria called Borrelia burdorferi until they start manifesting other clinical signs and symptoms of Lyme that include fatigue, visions changes, memory changes, mood swings, nervous system abnormalities and joint inflammation. In fact, the first outbreak of Lyme in 1975 in Lyme, CT was actually diagnosed based on what, at that time, was considered a bizarre outbreak of arthritis. When 11-year old Samanthas mother Anne checked her in at Dr. Ginger Nashs office, she had telltale signs of Lyme such as joint pain, headache and stomach upset after eating. But she had also been manifesting some of ...

Whole-genome sequencing is becoming a leading technology in the typing and epidemiology of microbial pathogens, but the increase in genomic information necessitates significant investment in bioinformatic resources and expertise, and currently used methodologies struggle with genetically heterogeneous bacteria such as the human gastric pathogen Helicobacter pylori. Here we demonstrate that the alignment-free analysis method feature frequency profiling (FFP) can be used to rapidly construct phylogenetic trees of draft bacterial genome sequences on a standard desktop computer and that coupling with in silico genotyping methods gives useful information for comparative and clinical genomic and molecular epidemiology applications. FFP-based phylogenetic trees of seven gastric Helicobacter species matched those obtained by analysis of 16S rRNA genes and ribosomal proteins, and FFP- and core genome single nucleotide polymorphism-based analysis of 63 H. pylori genomes again showed comparable ...
Rapid and reliable identification of Arcobacter and Helicobacter species, and their distinction from phenotypically similar Campylobacter species, has become increasingly important, since many of them are now recognized as human and/or animal pathogens. Matrix-associated laser desorption/ionization-time of flight (MALDI-TOF) MS has been shown to be a rapid and sensitive method for characterization of micro-organisms. In this study, we therefore established a reference database of selected Arcobacter, Helicobacter and Campylobacter species for MALDI-TOF MS identification. Besides the species with significance as food-borne pathogens - Arcobacter butzleri, Helicobacter pullorum, Campylobacter jejuni and Campylobacter coli - several other members of these genera were included in the reference library to determine the species specificity of the designed MALDI Biotyper reference database library. Strains that made up the reference database library were grown on Columbia agar, and yielded reproducible and
Inflammatory bowel disease (IBD) is thought to result from either an abnormal immunological response to enteric flora or a normal immunological response to a specific pathogen. No study to date has combined both factors. The present studies were carried out with an immunologically manipulated mouse model of IBD. Mice homozygous for the severe combined immunodeficiency (scid) mutation develop IBD with adoptive transfer of CD4+ T cells expressing high levels of CD45RB (CD45RB(high) CD4+ T cells). These mice do not develop IBD in germfree conditions, implicating undefined intestinal flora in the pathogenesis of lesions. In controlled duplicate studies, the influence of a single murine pathogen, Helicobacter hepaticus, in combination with the abnormal immunological response on the development of IBD was assessed. The combination of H. hepaticus infection and CD45RB(high) CD4+ T-cell reconstitution resulted in severe disease expression similar to that observed in human IBD. This study demonstrates ...

Terpenoids, also known as isoprenoids, are a large class of natural products consisting of isoprene (C5) units. There are two biosynthetic pathways, the mevalonate pathway [MD:M00095] and the non-mevalonate pathway or the MEP/DOXP pathway [MD:M00096], for the terpenoid building blocks: isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP). The action of prenyltransferases then generates higher-order building blocks: geranyl diphosphate (GPP), farsenyl diphosphate (FPP), and geranylgeranyl diphosphate (GGPP), which are the precursors of monoterpenoids (C10), sesquiterpenoids (C15), and diterpenoids (C20), respectively. Condensation of these building blocks gives rise to the precursors of sterols (C30) and carotenoids (C40). The MEP/DOXP pathway is absent in higher animals and fungi, but in green plants the MEP/DOXP and mevalonate pathways co-exist in separate cellular compartments. The MEP/DOXP pathway, operating in the plastids, is responsible for the formation of essential oil ...
Helicobacter pylori is one of the most common bacteria worldwide, estimated to infect half of the human population. The infection is usually established in childhood and persists for a lifetime, unless treated. Most individuals never experience symptoms from H. pylori infection and are not aware of that their stomachs are invaded by spiral-shaped bacteria. However, about 20% of the infected individuals develop severe diseases such as peptic ulcers and gastric cancers. Why some persons are asymptomatic while others develop disease is not fully understood, but it seems to be a combination of bacterial, host and environmental factors. Since H. pylori was discovered in 1982 research has been devoted to solving the mystery of H. pylori associated disease development, and much has been learned, but still there are many unanswered questions. H. pylori is described as a panmictic population where the clonal structure is lost due to high recombination frequencies, which makes genetic studies challenging. ...
Helicobacter pylori is the principal species of the genus Helicobacter that inhabits the gastric mucosa of the human stomach. It chronically infects billions of people worldwide1,2 and causes one of the most frequent chronic bacterial infections, involving more than 50% of the worlds population.3 H. pylori is one of the most genetically diverse of bacterial species, and is a major cause of at least 90% of duodenal ulcers, 70% of gastric ulcers, non-ulcer dyspepsia, gastro-oesophageal reflux disease, adenocarcinoma of the distal stomach and mucosa-associated lymphoid tissue (MALT) lymphoma in many societies.4. H. pylori infection presents a unique therapeutic challenge. Determining the optimal treatment is difficult because the organism lives in an environment not easily accessible to many medications. Several antibiotic agents are used worldwide to treat these infections; despite this range of antibiotics, the problem of drug resistance to most of them is well established.2,5. Reliable ...

Heat shock protein has been reported as a virulence factor of Helicobacter pylori. A 20kDa heat shock protein (HSP20) of H. pylori identified in this study was found to localize on the cell surface of H. pylori using Western blotting and immuno-gold labeled transmission electron microscopy. An hsp20-isogenic H. pylori SS1 was constructed which displayed equivalent in vitro adherence capability as that of the wild type but failed to colonize in the stomachs of BALB/c mice indicating the involvement of HSP20 in H. pylori colonization. By co-immunoprecipitation, unique interaction was shown between HSP20 and CagA revealing a probable chaperonic role of HSP20 in surface presentation of CagA in H. pylori lending its credence as collaborative a??partnera?? in H. pylori infection. DNA and protein sequences demonstrated the simple and unique 3-amino-acid residues (14tha??16th) of HSP20 showing their potential differentiating capability as epidemiological and gastroduodenal diseases marker of H. pylori ...

Helicobacter pylori is an important global pathogen infecting approximately 50% of the worlds population. This study was undertaken in order to estimate the prevalence rate of Helicobacter pylori infections among adults living in Turkey and to investigate the associated risk factors. This study was a nationally representative cross sectional survey, using weighted multistage stratified cluster sampling. All individuals aged ≥18 years in the selected households were invited to participate in the survey. Ninety two percent (n = 2382) of the households in 55 cities participated; 4622 individuals from these households were tested with the 13C-Urea breath test. Helicobacter pylori prevalence and associated factors were analysed by the t test, chi square and multiple logistic regression with SPSS11.0. The weighted overall prevalence was 82.5% (95% CI: 81.0-84.2) and was higher in men. It was lowest in the South which has the major fruit growing areas of the country. The factors included in the final model

Spiral bacteria, bacteria of spiral (helical) shape, form the third major morphological category of prokaryotes along with the rod-shaped bacilli and round cocci.[1][2] Spiral bacteria can be subclassified by the number of twists per cell, cell thickness, cell flexibility, and motility. The two types of spiral cells are spirillum and spirochete, with spirillum being rigid with external flagella, and spirochetes being flexible with internal flagella.[3]. ...

C57BL/6J mice carrying the Min allele of Adenomatous polyposis coli (Apc) develop numerous adenomas along the entire length of the intestine and consequently die at an early age. This short lifespan would prevent the accumulation of somatic genetic mutations or epigenetic alterations necessary for tumor progression. To overcome this limitation, we generated F(1) Apc(Min/+) hybrids by crossing C57BR/cdcJ and SWR/J females to C57BL/6J Apc(Min/+) males.

In the U.S. infection seems rare before the age of 10 but by age 60, 60% of persons have evidence of exposure to the bacterium. This qualifies Helicobacter pylori as being the most common chronic bacterial infection in humans.

Until the discovery of Helicobacter in 1982, ulcers were thought to be caused by stress. Now it is known that ulcers, in addition to gastritis, are caused by a bacterial infection of H. pylori. Though relatively easy to treat with antibiotics, H. pylori can be a risk factor for gastric cancer if it becomes a long-term infection (D. J. Kelly, 2004). The bodys natural defenses cannot combat H. pylori because white and killer T cells cannot easily get through the stomach lining. The defense cells eventually die, spilling their superoxide radicals on stomach lining cells, on which H. pylori can feed (Helicobacter Foundation, 2004). ...

Helicobacter Pylori este o bacterie (microb) care traieste in tubul digestiv uman, in special in stomac si duoden. Nu este un microb rar intalnit, peste jumatate din populatia in varsta de peste 50 de ani avandu-l, deci este mai neobisnuit sa nu ai acest microb decat sa il ai.Este interesant de stiut ca la nastere copilul nu are acest microb, iar pe masura inaintarii in varsta numarul purtatorilor creste progresiv… continue reading. ...

Treatment for atrophic gastritis, once properly diagnosed, does not require hospitalization. Treatment is home based. Medications can be prescribed in order to inhibit the secretion of gastric acid, and additional antibiotics will be necessary if infection with the Helicobacter spp bacteria is suspected. If vomiting persists, prokinetic agents (designed to enhance muscle activity in the gastrointestinal tract) may be prescribed as well.. ...
