ABSTRACT

Introduction: The importance of H. pylori as an etiological agent in gastroduodenal disease had suggested antibiotic treatment as a main target for the elimination of infection. The successful eradication of H. pylori infection was shown to resolve the gastritis, dramatically accelerate ulcer healing, reduce ulcer recurrence and the prophylactic effect on the recurrence of ulcer bleeding. Materials and Methods: In the present study a total six antimicrobial agents such as Ciprofloxacin, Metronidazole, Norfloxacin, Tetracyclin, Amoxycillin and Clarithromycin were used against 100 clinical isolates from patients with peptic ulcer, and non-ulcer dyspepsia. H. pylori was isolated from the gastric biopsies obtained from the clinical subjects. Results: Results of our study showed 100% resistance to Metronidazole (MIC > 256 μg/ml). 97% of the isolates were observed sensitive to Ciprofloxacin (MIC 0.38 μg), whereas Tetracyclin showed 96% sensitivity (MIC 0.25 μg - 0.125 μg). Resistance to amoxycillin, Norfloxacin, and Clarithromycin were 80%, 38% and 76% respectively (MIC > 256 μg/ml). Conclusion: It is observed that 96% - 97% of the clinical isolates were sensitive to Tetracycline and ciprofloxacin, where all isolates were found to be resistant to Metronidazole. Resistance to Amoxycillin and Clarithromycin were 80% and 76% respectively. Studies attributed the high level of resistance to the frequent use of the drugs to treat various other infections and ineffective drug control policy.
