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.. ...
Helicobacter bilis bacteria, coloured field emission scanning electron micrograph (FESEM). H. bilis is a Gram-negative spiral-shaped bacterium found in the intestines of rodents, dogs and cats. It may be zoonotic (transmissible from animals to humans) but research is inconclusive (as of 2009). Magnification: x22,850 when printed 10 centimetres tall. - Stock Image C001/3113
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 ...

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 ...
Author(s): Krstić V, Marinković D, Vakanjac Slobodanka, Lalošević D, Aleksić-Kovačevć} Sanja. Keywords:dog, Helicobacter spp., gastroscopy, histopathology, gastric tissue smears. This paper includes 50 dogs, differing in breed and sex, from 3 months to 12 years of age: 26 samples of endoscopic stomach biopsies were taken from ill animals which displayed chronic vomiting, 12 endoscopic biopsy samples of healthy dogs and 12 stomach samples of autopsied dogs. Helicobacter spp. and Gastrospirillum hominis findings were confirmed in 20 of the 26 ill dogs, 8 of the 12 autopsied animals, and 2 of the 12 healthy animals by histopathology and direct gastric tissue smears. In 26 endoscopic biopsies various clinical and endoscopic findings (7 cases of erosive and 4 of ulcerous gastritis, 12 cases of chronic gastritis and 2 of gastric reflux) were previously determined. Histopathological examination of stomach mucosa of 5 autopsied and Helicobacter positive dogs determined focal lymphocyte ...

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 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 ...

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). ...

Poultry represent an important source of foodborne enteropathogens, in particular thermophilic Campylobacter species. Many of these organisms colonize the intestinal tract of broiler chickens as harmless commensals, and therefore, often remain undetected prior to slaughter. The exact reasons for the lack of clinical disease are unknown, but analysis of the gastrointestinal microbiota of broiler chickens may improve our understanding of the microbial interactions with the host. In this study, the fecal microbiota of 31 market-age (56-day old) broiler chickens, from two different farms, was analyzed using high throughput sequencing. The samples were then screened for two emerging human pathogens, Campylobacter concisus and Helicobacter pullorum, using species-specific PCR. The gastrointestinal microbiota of chickens was classified into four potential enterotypes, similar to that of humans, where three enterotypes have been identified. The results indicated that variations between farms may have

Leptospirosis is whats known as a zoonotic disease. The bacterium lives in animal hosts and is transmitted between animals and to people via urine in fresh water. Its favorite host is the black rat, Rattus rattus (the rat so nice they named it twice), a nonnative species that was inadvertently transported to North America on explorers ships. For unknown reasons, its the only animal whose kidney can sustain continuous leptospira infections. The tubules of an infected rats kidney are lousy with bacteria and excrete hundreds of thousands in every drop of urine (10 million leptospira per milliliter, according to one study). Meanwhile, just 10 bacteria, injected into the abdomen, will send a laboratory hamster to violently hemorrhagic death within days. Leptospira is in a family of spiral-shaped bacteria called spirochetes, along with the bugs that cause syphilis and Lyme disease ...

Gastric biopsies from 71 patients were submitted to histopathological examination and genotyped by molecular methods (PCR y PCR-RFLP). The results indicated that 97.2% of the patients have alterations in the gastric mucosa, the presence of H. pylori was demonstrated in 44 patients and TT, CT and CC genotypes were detected in 12.7%, 60.6% and 26.8%, respectively. IL-1B genotypes were not associated with the severity of gastric mucosal damage in the studied population.

Background: Helicobacter pylori can utilize phenylphosphonate as a sole source of phosphorus, and it is able to transport the phosphonate N-phosphonoacetyl-L-aspartate. However, H. pylori does not have any genes homologous to those of the known pathways for phosphonate degradation in bacteria, indicating that it must have novel pathways for the transport and metabolism of phosphonates. Methods: Phenylphosphonate transport by H. pylori was studied in strains LC20, J99 and N6 by the centrifugation through oil method using [14C]-labeled phenylphosphonate. Results: The Michaelis constants of transport Kt and Vmax for phenylphosphonate showed similar kinetics in the three strains. The Arrhenius plot for phenylphosphonate transport rates at permeant concentrations of 50 µmol/L was linear over the temperature range 10-40 °C with an activation energy of 3.5 kJ/mol, and a breakpoint between 5 and 10 °C. Transport rates increased with monovalent cation size. The effects of various inhibitors were investigated:

Helicobacter pylori is a bacteria which colonises the human stomach. Essentially, it is believed that H pylori has always been present in humans and have co-evolved over 300 million years (1). H pylori (or its relative) is also found in other animals including primates, and carbohydrates on its surface are also found in human cells (1). The prevalence of the bacteria is highest in the developing world and increases proportionally with age (3). It is currently uncertain as to how the bacteria transmits between people, however there has been reports of transmission via contaminated endoscopes. Some studies also suggest that the faecal-oral route is not the primary route of transmission - H pylori is not normally found in human faeces (2). Thirty to fourty percent of the adult Australian population is colonised with H pylori (2), however less than 20 % of these people will ever develop symptoms from this infection (1). In addition, H pylori displays great genetic diversity and it is believed that ...
Under normal conditions, the Helicobacter bacteria are benign inhabitants of the intestinal tract, being found in several species, including domestic animals such as dogs, cats, ferrets and pigs, in wild animals such as cheetahs and monkeys, and in humans.

Det er to hovedårsaker til magesår: infeksjon med bakterien Helicobacter pylori og bruk av legemidler (NSAIDs) som "etser" slimhinnen i magesekken. Magesår forårsaket av bakterien Helicobacter pylori utgjør 75% av alle magesår, mens 25% får magesår som bivirkning til medisinbruk.. Det er ingen kjente sykdomsfaktorer som øker risikoen for komplikasjoner til magesår, men noen fellestrekk finnes: Pasienter med kompliserte magesår er mer utsatte for andre komplikasjoner. De fleste kompliserte sår er kroniske med mye arrvev, de trenger dypt inn i veggen, etser hull på blodkar eller det blir et gjennomgående hull der magesyre kan komme ut i bukhulen og forårsake alvorlig bukhinnebetennelse. Typisk for mange pasienter med kompliserte sår er en langvarig historie med gjentatte magesår, men noen pasienter har få eller ingen symptomer før komplikasjonen oppstår.. NSAIDs er som nevnt den store syndebukken. Det er legemidler som brukes bl.a. mot slitasjeplager i muskel- og ...

TY - JOUR. T1 - Helicobacter pylori strain types and risk of gastric cancer. T2 - A case-control study. AU - Enroth, H.. AU - Kraaz, W.. AU - Engstrand, L.. AU - Nyren, O.. AU - Rohan, T.. PY - 2000/10/16. Y1 - 2000/10/16. N2 - The aim of this novel endoscopy clinic-based case-control study was to explore the influence of different Helicobacter pylori strain types on the risk of gastric adenocarcinoma using isolated bacterial strains, tissue samples, and sera. We included 72 cases with gastric adenocarcinoma and 324 age- and sex-matched controls. Histological characterization, culture, molecular typing of H. pylori genes by PCR (cagA/vacA), conventional IgG ELISA, and immunoblotting (Western blot) for the CagA and VacA proteins were performed. With four tests combined, H. pylori infection was detected in 57 (79%) cases and 213 (66%) controls. A positive association between H. pylori infection and gastric cancer risk was found [odds ratio (OR), 2.1; 95% confidence interval, 1.1-3.9]. Type I (OR, ...
pathogen is C. jejuni, which accounts for 80-90% of all cases of recognized illness due to campylobacters and related genera. Other organisms that cause diarrheal disease include C. coli, C. upsaliensis, C. lari, C. hyointestinalis, C. fetus, A. butzleri, A. cryaerophilus, H. cinaedi, and H. fennelliae. The two Helicobacter species causing diarrheal disease, H. cinaedi and H. fennelliae, are intestinal rather than gastric organisms; in terms of the clinical features of the illnesses they cause, these species most closely resemble Campylobacter rather than H. pylori (Chap. 151) and thus are considered in this chapter. ...
