Although Helicobacter pylori has a significant impact on the occurrence of severe clinical syndromes, its exact ways of transmission and origin have not been identified. According to the results of some previously published articles, foods with animal origins play a substantial role in the transmission of H. pylori to humans. The present investigation was carried out to study the vacuolating cy...
objective(s):helicobacter pylori (h. pylori) is a pathogenic bacterium that colonizes the stomachs of approximately 50% of the world’s population. resistance of h. pylori to antibiotics is considered as the main reason for the failure to eradicate this bacterium. the aim of this study was to determine the rate of resistant h. pylori strains to various antimicrobial agents in different areas of ...
Background and aims: Helicobacter pylori is the primary cause of various diseases. This study was conducted to determine the existence of H. pylori in springs and surface water in Chaharmahal and Bakhtiari province. Methods: In this study, 29 water samples were collected from three different locations of Zayanderud River, 24 springs, and...
Background and purpose: The expression of growth factors, proteolytic enzymes, fibrogenic factors, and cytokines are altered in Helicobacter pylori (H. pylori) infected gastric mucosa. Matrix metalloproteinases (MMP) are a family of zinc-dependent homologous enzymes digesting most of the components of the extracellular matrix and basement membrane and are involved in remodeling and functioning o...
Background: A decreased rate of successful helicobacter pylori (H.pylori) infection treatment has revealed serious demand for more effective regimens to eradicate infection. Therefore, probiotics have recently been considered to increase the rate of antibiotic regimens efficacy in H. pylori infections. In current randomized controlled trial, we evaluated the effect of double strain probiotic co...
Background: Helicobacter pylori (H. pylori or Hp) has been strongly associated with the peptic ulcer diseases, chronic gastritis, ulcers, and gastric cancer. Genes associated with pathogenicity have been designated for H. pylori, and some of them appear to be related to more severe clinical consequences of the infection. The present study was conducted to determine cagA, vacA, cagE, iceA1, oipA...
Background: Helicobacter pylori has been classified as the class I carcinogenic agent by world health organization. Colonization of the human stomach with H. pylori is a risk factor for gastroduodenal diseases. The secreted vacA toxin is an important H. pylori virulence factor that causes multiple alterations in gastric epithelial cells and T cells. Several families of vacA alleles have been de...
development of a stool antigen immunoassay to detect helicobacter pylori infection requires monoclonal antibody against the specific antigen. alkylhydroperoxide reductase (ahpc) of helicobacter pylori has been described as a specific and unique enzyme for h. pylori and therefore, both h. pylori ahpc and anti-ahpc could be useful in the development of serologic and stool antigen tests, for detec...
conclusions: prevalence of h. pylori infection in our patients was similar to that of developing countries. severity of gastritis is correlated with the extent of h. pylori infection. moreover, the antibiotic resistance rate observed in this study signifies the ever-growing importance of further antibiotic sensitivity studies to help with proper treatment regimens against h. pylori. results: ov...
Objective(s) Due to increasing emergence of drug-resistance in Helicobacter pylori isolates, traditional plants are potentially valuable sources of novel anti-H. pylori agents. In this research, anti-H. pylori activity of the organic extracts of twenty native Iranian plants was determined against ten clinical isolates of H. pylori. Materials and Methods Disc diffusion was used to determine th...
