Helicobacter pylori is by far the best known Helicobacter species primarily because humans infected with it may develop gastrointestinal tract diseases such as stomach inflammation, stomach ulcers, duodenal ulcers, stomach cancers of the nonlymphoma type, and various subtypes of extranodal marginal zone lymphomass, e.g. those of the stomach, small intestines, large intestines, and rectumn. (wikipedia.org)
Ammonia production is of great importance for the gastric pathogen Helicobacter pylori as a nitrogen source, as a compound protecting against gastric acidity, and as a cytotoxic molecule. (pasteur.fr)
Phylogenetic trees based upon the sequences of H. pylori amiE and amiF genes and their respective homologs from other organisms as well as the amidase gene distribution among Helicobacter species are strongly suggestive of amidase acquisition by horizontal gene transfer. (pasteur.fr)
Mongolian gerbils infected with Helicobacter pylori (Hp) develop goblet cell intestinal metaplasia and adenocarcinoma, but the presence of SPEM has not been studied in gerbils. (fujita-hu.ac.jp)
[1] H. pylori can be diagnosed by testing the blood for antibodies , a urea breath test , testing the stool for signs of the bacteria, or a biopsy of the stomach. (wikizero.com)
Spasmolytic polypeptide-expressing1
Here we demonstrated that an inflammasome molecule, absent in melanoma 2 (Aim2), was upregulated in patients with gastric cancer and in spasmolytic polypeptide-expressing metaplasia of chronically Helicobacter felis-infected stomachs in mice. (jci.org)
Metaplasia1
Spasmolytic polypeptide (TFF2)-expressing metaplasia (SPEM) is observed in mucosa adjacent to human gastric cancer and in fundic glands showing oxyntic atrophy in Helicobacter felis-infected mice. (fujita-hu.ac.jp)
It is important to diagnose H. salomonis and other Helicobacter heilmannii sensu lato infections in patients with the cited upper gastrointestinal tract diseases, including in particular extranodal marginal zone lymphoma of the stomach, because some of them have been successfully treated and cured using antibiotic-based drug regimens (e.g.amoxicillin, clarithromycin, plus a proton pump inhibitor or metronidazole, clarithromycin, plus a proton pump inhibitor) directed against the instigating bacterium.

Salomonis2
Helicobacter salomonis (H. salomonis) is a species within the Helicobacter genus of Gram-negative bacteria. (wikipedia.org)
citation needed] Helicobacter salomonis bacteria are detected in the stomachs of their natural hosts - cats, dogs, and rabbits. (wikipedia.org)
Species6
We tested for the presence of the amiE and amiF genes and for amidase and formamidase activities in eleven Helicobacter species. (pasteur.fr)
Among the gastric species, H. acinonychis possessed both amiE and amiF, H. felis carried only amiF, and H. mustelae was devoid of amidases. (pasteur.fr)
H. muridarum, which can colonize both mouse intestine and stomach, was the only enterohepatic species to contain amiE. (pasteur.fr)
Since amidases are found only in Helicobacter species able to colonize the stomach, their acquisition might be related to selective pressure in this particular gastric environment. (pasteur.fr)
Most Shigella species cause mild symptoms like slight fever, chills, stomach cramps, and sometimes bloody stool that can last up to a week. (giantmicrobes.com)
The two bacteria species best known to cause conjunctivitis in cats are Chlamydia felis and Mycoplasm a spp. (vin.com)
Strains3
The colonization ability of the strains, the intensity of gastritis and gene expression of various inflammatory cytokines in the stomach were determined at 9 weeks after experimental infection. (biomedcentral.com)
High-level antral colonization was seen for 4 strains, while colonization of 4 other strains was more restricted and one strain was not detected in the stomach at 9 weeks post infection. (biomedcentral.com)
A reduced antral expression of H + /K + ATPase was seen in the stomach after infection with 3 highly colonizing strains and 2 highly colonizing strains caused an increased gastrin expression in the fundus. (biomedcentral.com)
This bacterium has been propagated in mice for up to 28 months and was able to induce MALT lymphoma in the stomachs of these animals [ 18 ]. (biomedcentral.com)
