Background: The objective of this study was to evaluate the antibiotic resistance pattern of Helicobacter pylori strains isolated from patients in Isfahan province.
Materials and methods: Gastric antrum biopsy specimens of patients undergoing endoscopy were cultured. The samples with the growth of H. pylori underwent antibiotic susceptibility test by disk diffusion method.
Reaults: Of 96 samples, 50 samples (53%) were positive for H. pylori. The rates of antibiotic resistance were as follows: amoxicillin, 6%; azithromycin, 20%; furazolidone, 22%; levofloxacin, 16%; metronidazole, 20%; rifampin, 12%; and tetracycline, 22%.
Conclusion: H. pylori strains in our area have high rates of resistance to azithromycin, levofloxacin, metronidazole, tetracycline, and furazolidone.
