Abstract
AIM: To analyze the resistance of clinical isolated H. pylori strain to common antibiotics.
METHODS: H. pylori strains were obtained by inoculating the specimens of 61 patients in the selective media for 96 h at 37°C under microaerophilic conditions. Kirby-Bauer test was performed to detect the drug sensitivity of the 61 isolated H. pylori strains to metronidazole, clarithromycin, amoxicillin and furazolidone.
RESULTS: The antibiotic resistant rates of H. pylori strains to metronidazole, clarithromycin, amoxicillin and furazolidone were 54.1%, 37.7%, 41.0% and 45.9%, respectively, and there were no significant difference among them (P > 0.05). The resistance H. pylori strains to metronidazole was related to the sex of patients (P = 0.037), and the resistance of H. pylori strains to metronidazole, clarithromycin and amoxicillin was closely related to the history of antibiotic usage (P = 0.028; P = 0.034; P = 0.005). No significant relationship existed between the antibiotic resistance of H. pylori in the type of disease and the age of patients (P > 0.05).
CONCLUSION: H. pylori has high resistance to metronidazole, clarithromycin, amoxicillin, and furazolidone, which is associated with the history of antibiotic application, but not with the disease category and age of patients.
