Résumé
Helicobacter pylori [H.pylori] is implicated in acute superficial gastritis, chronic atrophic gastritis, gastric carcinoma and MALT [Mucosa Associated Lymphoid Tissue] associated lymphoma. Prevalence of H. pylori antibiotic resistance is increasing and affect the efficacy of treatment. Our aim was to improve infected patients with new generations of antibiotics. 88 peptic ulcer patients recruited from gastroenerology and endoscopy unit at Suez Canal University, 5 gastric biopsies were taken from each and were examined for H. pylori by histopathology, rapid urease test and culture. Antibiotic susceptibility test was performed to: metronidazole, clarithromycin, amoxicillin, amoxicillin calvulanic acid, levofloxacin, tetracycline, ciprofloxacin, ofloxacin, ceftriaxone, cefoperazone and ceftazidime. Night-two% were positive for H. pylori, while 20% of the studied population were positively cultured .The results of antibiotic sensitivity were:100% of patients were sensitive to clindamycin, 87.5% sensitive to erythromycin, 68.8% sensitive to amoxicillin and levofloxacin, 50% sensitive to azithromycin and tetracycline, 25% sensitive to clarithromycin and 18.8% sensitive to amoxicillin and cavulanic acid. H. pylori resistance towards different antibiotics has increased. new promising results regarding clindamycin and erythromycin
