Twenty of the 27 strains resistant to clarithromycin were also resistant to metronidazole. None of the strains were resistant to amoxicillin or tetracycline.CONCLUSION: A high percentage of patients from Bahrain were infected with resistant strains of Helicobacter pylori. Antibiotic resistance monitoring is very important and unified national treatment policies are needed.
