A solution of 10 \{mmol/L\} HClO 4+10 mmol/L NaCl was selected as the supporting electrolyte. The calibration plots for Tl(Ⅰ) concentration in the range of 2×10 -9 -1×10 -7 mol/L were obtained. The detection limit was 5×10 -10 mol/L. For the solutions of 4 0×10 -9 mol/L thallium added before the urine sample pretreatment procedure, the average recovery was 105 6% with a relative standard deviation(RSD) of 15 5%.展开更多
目的比较3种药敏检测方法检测替加环素对多重耐药鲍曼不动杆菌敏感性的差异。方法收集2018年临床分离耐碳青霉烯类鲍曼不动杆菌60株,采用MIC Test Strip(MTS)法、VITEK-2法、纸片扩散法分别检测替加环素对耐碳青霉烯类鲍曼不动杆菌的敏...目的比较3种药敏检测方法检测替加环素对多重耐药鲍曼不动杆菌敏感性的差异。方法收集2018年临床分离耐碳青霉烯类鲍曼不动杆菌60株,采用MIC Test Strip(MTS)法、VITEK-2法、纸片扩散法分别检测替加环素对耐碳青霉烯类鲍曼不动杆菌的敏感性。结果按照FDA标准,以MTS法为参考,VITEK-2法的一致率较高,纸片扩散法的一致率较低。Vitek-2法的MIC值比MTS法的MIC值低1~2个稀释度,利用MTS法检测替加环素对耐碳青霉烯鲍曼不动杆菌的耐药率达到23.3%,出现耐药株。结论对于耐碳青霉烯类鲍曼不动杆菌,Vitek-2法和纸片扩散法均不适合检测替加环素的敏感性,不能作为常规方法,需用MTS法确认。展开更多
