چکیده باکتریhelicobacter pylori دارای خانواده ای از پروتئین های غشاء خارجی شامل 32 عضو است. چسبیدن با واسطه برخی از این پروتئین های غشاء خارجی سبب القای تولید اینترلوکین-8 می گردند. یکی از این پروتئین های غشاء خارجی، 33 -35 کیلو دالتون بوده و توسط ژن پروتئین التهابی غشائ خارجیa (oipa) بیان میگردد، که نقش مهمی را در بیماری زایی helicobacter pylori ایفا می نماید. .هدف ما از این مطالعه جداسازی و...
Background and Aim: Gastrointestinal disease is one of the most common infectious diseases in the world. One of the most important causes is Helicobacter pylori infection. Considering the importance of this bacterium and its different prevalence in different parts of the country, this study was conducted to determine the prevalence of Helicobacter pylori infection and its related factors in 9-1...
The aim of this study was to determine the prevalence and identify the species of gastric Helicobacter in the stool of dogs with gastritis. The study was carried out on thirty dogs of different breeds, of both genders and of various ages, diagnosed with gastritis. Helicobacter spp. was detected in stool samples using the nested-PCR method. Helicobacter bacteria were identified in stool samples ...
Infection with Helicobacter spp. is increasingly linked with hepatobiliary inflammation and neoplasia in people and in a variety of animals. We sought to determine if Helicobacter species infection is associated with cholangiohepatitis in cats. Deoxyribonucleic acid was extracted from tissue blocks from cats with cholangiohepatitis (32), noninflammatory liver disease (13), and cats with normal ...
In order to improve simultaneous detection and identification of Helicobacter genus in general and Helicobacter pylori specifically and reduce the number of amplifications needed, we established a multiplex PCR. In this study, two pairs of primers: Hcom1 and Hcom2 specific for Helicobacter genus, Hicd1 and Hicd2 specific for Helicobacter pylori species were used. To determine the sensitivity of...
Background & Objective: Helicobacter pylori is a bacterium responsible for one of the most prevalent infections found in humans worldwide. Considering the importance of this infection and its different prevalence in different regions of Iran, this study was conducted to determine the prevalence of Helicobacter pylori in Chahar Mahal and Bakhtiari as a high-risk province. Materials & Methods :...
BACKGROUND The lipopolysaccharide of Helicobacter pylori plays an important role in colonization and pathogenicity. The present study sought to compare structural and biological features of lipopolysaccharides from gastric and enterohepatic Helicobacter spp. not previously characterized. MATERIALS AND METHODS Purified lipopolysaccharides from four gastric Helicobacter spp. (H. pylori, Helicob...
effect of helicobacter pylori eradication or of ranitidine plus metoclopramide on helicobacter pylori-positive and of bismuth or ranitidine plus metoclopramide on helicobacter pylori-negative functional dyspepsia. a randomized, controlled follow-up study.
Prevalence of Helicobacter is mostly unknown in laboratory animals in Thailand. The 221 mice feces/cecum from 8 universities, 2 pharmaceutical companies and 3 research institutions in Thailand were surveyed for the prevalence and distribution of Helicobacter species by using the Electrochemical DNA chip. Helicobacter were detected 23/46 samples in Specific Pathogen Free (SPF) and 168/175 in con...
Helicobacter pylori is motile curved shaped gram negative and microaerophilic bacilli that positive for catalase. Oxidase and urease. Fordetection of helicobacter pylori, there are different diagnostic methods with different sensivity and specifity. The best method is histological examination and search for helicobacter pylori in the specimens by specific staining. In papers be said pro...
