【摘要】 目的 :研究H pylori对甲硝唑耐药与细菌定植密度间的关系 .方法 :用E -test方法检测 10 9株H pylori菌株对甲硝唑的敏感性 ;胃粘膜活检标本经Warthing -Starry染色后观察评定H pylori定植密度 .结果 :10 9株H pylori菌株的甲硝唑耐药率为 6 7 89% ;H pylori定植密度的不同等级在H pylori菌株甲硝唑耐药率上无显著性差异 .结论 :H pylori对甲硝唑的敏感性与细菌定植密度无关更多还原

【Abstract】 Objective: To study the relationship of metronidazole resistance and colonization density of H. Pylori. Methods: Testing metronidazole susceptibilities of 109 H. Pylori strains by the use of the Epsilometer test (E-test); analyzing colonization density of H. Pylori in the gastric biopsy specimens by Warthing-starry stain. Results: In 109 H. Pylori strains, metronidazole resistant rate was 67.89%. There was no significant difference in the metronidazole resistant rate and colonization density of H. Pylori. Conclusion: There was no relation between metronidazole resistant rate and colonization density of H. Pylori.更多还原
