… Helicobacter pylori strains has been demonstrated to be more frequent than that seen in other
prokaryotes. Point mutations in … of pathogenicity or antibiotic susceptibility of individual H. …

… This study was done to evaluate the prevalence of primary antibiotic resistance of H. pylori,
and to evaluate the effect of point mutations of 23S rRNA on the rate of eradication of H. …

… We can therefore postulate that this lack of binding is due to a modification in the ribosomal
structure following the mutation. In summary a strong association between point mutations at …

… Helicobacter pylori eradication therapy is resistance to clarithromycin. The resistance is due
to three point mutations … method to detect these mutations directly on biopsy specimens. We …

… In addition, we observed that novel point mutations are emerging in H. pylori isolates. In
the current study, three other point mutations that have already been described in Western …

… pylori cell lysis and mutation assessment presented in this report permits consideration of
24 h molecular antimicrobial susceptibility testing directly … The presence of either mutation, …

… Clarithromycin resistance against H. pylori is associated with point mutations in the 23S
ribosomal RNA (rRNA) gene. When a point mutation occurs, the binding of clarithromycin to the …
