BACKGROUND The vacA, cagA and babA2 genotypes of Helicobacter pylori are associated with gastric pathology. The objectives were to determine the frequency of infection and distribution of the vacA, cagA and babA2 genotypes of H. pylori in patients with gastric ulcer, chronic gastritis and gastric cancer, and to evaluate the association of virulent genotypes with diagnosis. METHODS We studied ...
Infection with Helicobacter pylori is associated with different human gastric diseases. Biochemical studies, in vitro adherence assays, and in vivo animal models revealed that epithelial attachment of H. pylori can be mediated by the blood-group antigen-binding adhesin (BabA) targeting human Lewis(b) surface epitopes. Studies with transgenic mice expressing the Lewis(b) epitope have shown that ...
background: blood group antigen binding adhesin ( baba2 ) , is essential for attachment of helicobacter pylori (h. pylori) to the epithelial cell layer and is the most important adhesin of h. pylori . the prevalence rate of the baba2 gene varies in different geographic areas. the aim of this study is to determine the frequency of the baba2 gene in patients with different clinical outcomes. mate...
BACKGROUND AND OBJECTIVES Helicobacter pylori has been strongly associated with peptic ulcer diseases, chronic gastritis, ulcers, and reported as a risk factor for gastric cancer, too. The vaculating cytotoxin (vacA), the cytotoxin associated genes (cagA), the induced by contact with epithelium factor antigen (iceA gene), blood adhesion binding antigen (babA2), and outer membrane protein oipA h...
Helicobacter pylori virulence factors have been suggested to be important in determining the outcome of infection. The H. pylori adhesion protein BabA2 is thought to play a crucial role in bacterial colonization and in induction of severe gastric inflammation, particularly in combination with expression of CagA and VacA. However, the influence of these virulence factors on the pathogenesis of H...
Abstract Background and Objective: BabA2 and Hpa genes are involved in adherence of Helicobacter pylori (H.pylori) to gastric mucosal tissue. This study aimed to investigate the frequency of these genes in isolates of H. pylori from gastric biopsies and their relationship with gastritis, peptic ulcer and gastric cancer. M...
BACKGROUND AND AIMS We tested if host gastric Lewis antigens and the babA2 genotype of Helicobacter pylori correlated with clinicohistological outcome. METHODS We enrolled 188 dyspeptic patients (45 with duodenal ulcer, 45 with gastric ulcer, and 98 with chronic gastritis) with H pylori infection, proved by culture and gastric histology, reviewed by the updated Sydney system. Gastric expressi...
Background and purpose: cagA, vacAs1 and babA2 in Helicobacter pylori are important virulence factors associated with gastrointestinal diseases. The prevalence of these genes and their association with gastrointestinal disease is different around the world. Materials and methods: In a cross-sectional study, 1500 patients with gastroduodenal disorders were enrolled. They attended Imam Khomeini ...
زمینه و هدف : هلیکوباکترپیلوری از مهم‌ترین پاتوژن‌های معده در انسان است. حضور ژن‌های babA2 و hsp در اتصال به سلول‌های اپیتلیال معده و بیماری‌زایی باکتری نقش دارد. این مطالعه به منظور تعیین فراوانی ژن‌های babA2 و hsp در سویه‌های هلیکوباکترپیلوری جدا شده از بیماران مبتلا به اختلالات گوارشی انجام شد. روش بررسی : این مطالعه توصیفی – تحلیلی روی 80 بیمار با اختلالات گوارشی مراجعه کننده به مرکز آموزش...
سابقه و هدف: ژن های caga، vacas1و baba2 در هلیکوباکتر پایلوری از مهم ترین فاکتورهای ویرولانس مرتبط با بیماری های گاسترودئودنال هستند. میزان فراوانی و ارتباط این ژن ها با انواع بیماری های گوارشی در مناطق جغرافیایی مختلف، متفاوت است.هدف از این مطالعه تعیین ارتباط ژن های caga،vacas1 و baba2 در هلیکوباکتر پایلوری با بیماری های گاسترودئودنال بوده است. مواد و روش ها: در مطالعه توصیفی مقطعی حاضر 1500 ...
