Abstract

Background: Helicobacter pylori (H. pylori) is the most common cause of gastric infections worldwide. Due to antibiotic resistance and adverse effects, phytotherapy and phage therapy have been a research focus as an alternative therapy for H. pylori infection. Objectives: To assess the medicinal plant extracts and bacteriophages as a treatment of H. pylori infection. Methodology: Thirty five gastric biopsies were cultured for H. pylori isolation. Screening of medicinal plants extract efficiency was done by Disc diffusion method. Minimum inhibitory concentrations of extracts were assessed. In vivo effect of Punica granatum peel extract was tested by bacterial density and histopathology in rats. Sewage water samples were screened for H. pylori specific bacteriophages. Single plaque isolation technique was used for phage purification. Results: Ten out of 35 (28.57%) patients had positive gastric biopsy for H. pylori by culture. Four out of 10 (40%) isolates were resistant to all antibiotics. Inhibitory effect of Rosemarinus officinalis, Syzygium aromaticum, Rhus coriaria and Ammi visagna on H. pylori was detected. Punica granatum extract was the most efficient in vitro. In vivo, Punica granatum peel extract caused significant reduction of bacterial density (P
