Evaluation of Mutations in 23S rRNA, rdxA and frxA Genes of Helicobacter pylori in Paraffin-Embedded Gastric Biopsy Specimens from Iranian Gastric Cancer and Gastritis Patients.

Abstract excerpt

PURPOSE: Helicobacter pylori (H. pylori) infection is considered as one of the main cause of gastric cancer. Treatment failure of the infection often occurs due to antibiotic resistance. Herein, we aimed to evaluate the mutations in 23S rRNA gene of H. pylori which are associated with clarithromycin resistance and in rdxA and frxA genes of the bacterium which may be associated with metronidazole resistance, in...
