Prevalence of EPIYA motifs in Helicobacter pylori strains isolated from patients with gastroduodenal disorders in northern Iran
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...
متن کاملvacA genotypes in Helicobacter pylori strains isolated from children with and without duodenal ulcer in Brazil.
Data concerning the association between vacA genotypes and disease in children in both developed and developing countries are scarce, especially because of the small number of children with a duodenal ulcer studied. The vacA genotypes of Helicobacter pylori strains obtained from 65 children (24 with a duodenal ulcer and 41 without a duodenal ulcer; 33 girls; mean age, 10.2 years; age range, 1 t...
متن کاملInhibitory Effect of Probiotic Bacteria Isolated from Camel Milk on Clinical Strains of Drug-Resistant Helicobacter pylori
ABSTRACT Background and Objectives: Helicobacter pylori is the most common cause of gastritis and ulcer worldwide. Treatment of such infections may lead to failure due to drug resistance. This study aimed to investigate the antimicrobial effects of bacteria present in camel milk on the growth of drug-resistant clinical isolat...
متن کاملDiscrimination of Dominant H. pylori Strains Isolated from Patients with Different Gastroduodenal Pathologies by Protein Profiling
It is not clear what factors determine divergent outcomes of infections caused by H. pylori . In the present study, the protein profiles of different strains of H. pylori, isolated from three groups of patients with ulcerative disease, non-ulcerative gastritis and cancer disease, were analyzed using 1DSDS-PAGE. The patterns of different H. pylori strains were highly divergent. About 30.76% (7 b...
متن کاملAntimicrobial susceptibility of Helicobacter pylori strains isolated in Bangladesh.
Antimicrobial susceptibility of 120 Helicobacter pylori isolates to metronidazole, tetracycline, clarithromycin, and amoxicillin was determined, and 77.5, 15, 10, and 6.6% of the isolates, respectively, were resistant. Only rdxA inactivation and both rdxA and frxA inactivation were responsible for metronidazole resistance in 66% (8 of 12) and 33% (4 of 12) of the isolates, respectively.
