幽门螺杆菌临床分离株耐药性研究

Study of antibiotic resistance of clinical isolates of helicobacter pylori

目的 分析石家庄地区幽门螺杆菌临床分离株对多种抗生素的药物敏感性情况。方法 2 0 0 2 - 11～2 0 0 3- 12河北医科大学第三医院消化科采用滤纸片琼脂扩散法检测 5 5株临床分离株。对甲硝唑、奥硝唑、阿奇霉素、克拉霉素 ,阿莫西林、四环素、呋喃唑酮的药物敏感性。结果 甲硝唑耐药率 92 73% ,奥硝唑耐药率85 4 5 % ,阿奇霉素耐药率 4 5 4 5 % ,克拉霉素耐药率 9 0 9% ,阿莫西林、四环素、呋喃唑酮耐药率均为 0。结论 石家庄地区幽门螺杆菌对甲硝唑、奥硝唑、阿奇霉素耐药率较高 ,同时存在克拉霉素耐药 ,未发现阿莫西林、四环素、呋喃唑酮耐药株。

Objective To analyze the susceptible range and antibiotic resistance of clinical isolates of Helicobacter pylori(H.pylori) in Shijiazhuang area.Methods (1)H.pylori strains:55.(2)Drugs:Metronidazole,Ornidazole,Azithrumyein,Clarithromycin,Amoxicillin,Tetracycline and Furazolidone.(3)Sensitive test:filter paper agar diffusion method.Results The antibiotic resistance rate of Metronidazole,Ornidazole,Azithrumyein,Clarithromycin,Amoxicillin,Tetracycline and Furazolidone was 92.73%,85.45%,45.45%,9.09%,0,0,0,respectively.Conclusion The antibiotic resistance rate of H.pylori from Shijiazhuang area to Metronidazole,Ornidazole and Azithrumyein are very high,and the resistant strains to Clarithromycin has been found.There are no resistant strains to Amoxicillin,Tetracycline and Furazolidone.
