Discriminatory power of RAPD, PCR-RFLP and southern blot analyses of ureCD or ureA gene probes on Helicobacter pylori isolates.

چکیده
The genetic diversity of 33 Nigerian Helicobacter pylori isolates were studied using RAPD, PCR-RFLP and Southern blot analysis of ureA or ureCD gene probes. RAPD was able to distinguish the following number of isolates using the primers 3880: 5'-AAGAGCCCGT-3' (28), 3881 :5'-AACGCGCAAC-3' (33) and OPH8 :5'-GAAACACCCC-3' (25). Southern blot analysis using the ureCD probe was also able to distinguish the 12 isolates tested into ten different patterns. The PCR-RFLP technique distinguished all 33 isolates into six types. In conclusion, considering typeability, discriminatory power, and convenience, RAPD with the 3881 primer was considered the most useful technique.

We compared the robustness and discriminatory power of the enterobacterial repetitive intergenic consensus (ERIC) and random amplified polymorphic DNA (RAPD) fingerprinting methods for detecting cases of mixed Helicobacter pylori infection in Peruvian shantytown residents. H. pylori isolates from 63 participants were cultured, and five single colonies and a pool of additional colonies from each...

We characterized 38 Helicobacter isolates, including 22 from gastric biopsy samples obtained from 14 rhesus monkeys and single isolates from 16 monkeys in a different colony. Biochemical profiles of these isolates were nearly identical to that of Helicobacter pylori ATCC 43504. Restriction fragment length polymorphism (RFLP) analysis indicated that each infected monkey harbored one to four stra...
متن کاملGenetic Diversity and Drug Resistance of Helicobacter pylori Strains in Isfahan, Iran
Objective(s) Resistance to antimicrobial agents, particularly metronidazole and clarithromycin, is frequently observed in Helicobacter pylori and may be associated with treatment failure. This resistance rate varies according to the population studied. The aim of this study was to assess the pattern of antimicrobial resistance of H. pylori isolates from dyspeptic patients in Isfahan. Material...

Background: Clarithromycin resistance in Helicbacter pylori has been found to be associated with point mutations in 23s rRNA gene leads to reduced affinity of the antibiotic to its ribosomal target or changing the site of methylation. The aim of this study was to determine the most important point mutations in 23s rRNA gene in H. pylori that are closely related to clarith-romycin resistance amo...
