Metronidazole and tetracycline E tests were compared to an agar dilution method for the antimicrobial susceptibility testing of Helicobacter pylori. Sixteen strains were tested by using tetrazolium egg yolk (TEY) agar. The characteristic E test inhibition ellipse was clearer on TEY agar than on standard blood agar and gave results comparable to those of the agar dilution test. The use of TEY medium is preferable to that of blood agar medium in E test MIC determinations for H. pylori.
将甲硝唑和四环素E试验与琼脂稀释法用于幽门螺杆菌的抗菌药敏试验进行比较。使用十六烷基三甲基溴化铵蛋黄(TEY)琼脂对16株菌株进行检测。在TEY琼脂上,特征性的E试验抑菌椭圆比在标准血琼脂上更清晰,且结果与琼脂稀释试验相当。在幽门螺杆菌E试验最低抑菌浓度(MIC)测定中,使用TEY培养基比血琼脂培养基更可取。
