The Pan-Drug Resistant (PDR), Helicobacter pylori remains an intractable challenge in public health worldwide and this pathogenicity is mainly due to the presence of a cytotoxin-associated gene A (CagA) and vacuolating cytotoxin A (VacA).

To determine if disruption of the cagA gene of Helicobacter pylori (H pylori) has an effect on the expression of other proteins at proteome level.Construction of a cagA knock out mutant Hp27_Delta cagA (cagA(-)) via homologous recombination with the wild-type strain Hp27 (cagA(+)) as a recipient was performed.

Helicobacter pylori (H.pylori) is associated with chronic gastritis, peptic ulcers, gastric adenocarcinomas and mucosa associated tissue lymphomas. Cytotoxin associated gene A (CagA) is one of the virulence factors of H.pylori. It is hypothesized that reactive oxygen species (ROS) play roles in H.pylori associated disease especially in development of ...

Association Between Cerebral Ischemia and Cytotoxin-Associated Gene-A–Bearing Strains of Helicobacter pylori [PDF]
Background and Purpose— Studies on Helicobacter pylori infection and risk of ischemic stroke yielded variable results. Infection with more virulent H. pylori strains, such as cytotoxin-associated gene-A (CagA)–bearing strains, may be of particular ...

Helicobacter pylori and Its Role in Gastric Cancer
Gastric cancer is a challenging public health concern worldwide and remains a leading cause of cancer-related mortality. The primary risk factor implicated in gastric cancer development is infection with Helicobacter pylori. H.

Mutation of the cytotoxin-associated cagA gene does not affect the vacuolating cytotoxin activity of Helicobacter pylori [PDF]
Helicobacter pylori now is recognized as an etiological agent in chronic superficial gastritis and peptic ulcer disease. Although only about 60% of H. pylori isolates produce an immunodominant 128-kDa antigen (CagA; cytotoxin-associated gene product), virtually all H. pylori-infected patients with duodenal ulceration develop a serologic response to the

Modulation of Host Cell Signal Transduction Pathways by Helicobacter Pylori Infection
Bacterial pathogens modulate host cell signal transduction responses to establish infection and cause disease. The purpose of the present summary, first presented at the Canadian Helicobacter Study Group meeting, is to discuss current knowledge of ...

Giriş: Sitotoksin ilişkili A genli Helicobacter pylori (SİAGHP), en çok virülansı olan H. pylori tipidir ve halen endotelyal disfonksiyon ile ilişkisi belirsizdir. Bu nedenle biz SİAGHP’nin endotelyal bağımlı dilatasyon üzerine etkilerini ve C-reaktif protein (CRP) düzeyleri ile ilişkisini normotansif bireylerde araştırdık.

Genotyping of Helicobacter pylori Virulence Genes cagA and vacA: Regional and National Study
Helicobacter pylori (H. pylori) plays a crucial role in the pathogenesis of gastritis, peptic ulcer, and gastric cancer. The presence of pathogenicity islands (PAI) genes contributes to the pathogenesis of many gastrointestinal disorders.

CagA and VacA Helicobacter Pylori Antibodies in Gastric Cancer
BACKGROUND: Infection with different genotypes of virulent Helicobacter pylori strains (cytotoxin-associated gene A [CagA]-and/or vacuolating cytotoxin A [VacA]-positive) can play a role in the development of atrophic gastritis, duodenal ulcer (DU) and ...
