| enzyme-linked immunosorbent assay for serodiagnosis of helicobacter pylori in dyspeptic patients and volunteer blood donors. | helicobacter pylori, an important etiological agent in the development of gastritis, peptic ulcer and gastric carcinoma, can be detected by the enzyme-linked immunosorbent assay (elisa). our objectives were: (1) to evaluate the efficacy of a commercial elisa kit (pyloriset eia-g iii) in sensitivity, specificity, positive predictive value (ppv), negative predictive value (npv), and accuracy for diagnosis of h. pylori infection in thai dyspeptic patients in khon kaen thailand; and (2) to examine t ... | 2006 | 17333740 |
| antimicrobial susceptibility of helicobacter pylori isolated from gastric biopsies in dyspeptic patients. | the objective of this study was to evaluate the prevalence of antimicrobial resistance in helicobacter pylori isolated from the antrum and corpus of dyspeptic patients in khon kaen, thailand, and to compare the antimicrobial susceptibility patterns of h. pylori isolated from the antrum and corpus in individual patients. antimicrobial susceptibility was determined by disk diffusion, studying susceptibility to metronidazole, clarithromycin, amoxicillin, erythromycin, ciprofloxacin, and tetracyclin ... | 2008 | 19062703 |
