زمینه و هدف : سویه های باکتری هلیکوباکترپیلوری که دارای پروتئین cag a (cytotoxin associated gene a) می باشند؛ استعداد بیشتری برای ایجاد بیماری دارند. این پروتئین بیماری زایی باکتری را با افزایش تولید سیتوتوکسین در سلول میزبان تسریع می نماید. این مطالعه به منظور تعیین فراوانی آنتی بادی ضد caga در افراد آلوده به هلیکوباکترپیلوری در استان گلستان انجام شد. روش بررسی : این مطالعه توصیفی روی 676 نفر ...

Background: Cytotoxin-associated gene A (CagA)-positive strains of Helicobacter pylori are associated with gastroduodenal diseases. Evidences have suggested that the type of H pylori CagA EPIYA motifs may be associated with specific disorders (i.e., gastritis, peptic ulcer, or gastric cancer).  We investigated the prevalence of different EPIYA motifs (A, B, C, or D) in H. pylori strains is...

We investigated the presence of the gene of subtilase cytotoxin (SubAB), described in certain highly virulent verocytotoxigenic E. coli strains, in isolates from Argentina and its relation with other virulence factors. The gene subA was present in eae-negative strains mostly associated with saa, vt2 and ehxA genes.

background :   vaculating cytotoxic a ( vaca ) gene is one of the multiple helicobacter pylori genotypes that produce a cytotoxin protein (vaca).this gene is a major cause of chronic peptic ulcers and gastric cancer. the aim of this study was to determine the correlation between vaca gene with peptic ulcer disease (pud) and non-ulcer dyspepsia (nud).   methods :    this was a case control study...

The vacuolating cytotoxin and the cytotoxin-associated protein, encoded by vacA and cagA, respectively, are important virulence determinants of Helicobacter pylori. Sixty-five H. pylori strains were isolated from dyspeptic patients (19 with peptic ulcer disease, 43 with chronic gastritis, and 3 with gastric cancer) and studied for differences in the vacA and cagA genes and their relationship to...
