摘要:

目的 比较4种肺炎链球菌体外药物敏感性试验板条检测结果的一致性。方法 以浓度梯度法为对比方法。采用美国BD公司Phoenix100 SMIC板条(简称BD-SMIC)、法国生物梅里埃公司Vitek 2 Compact GP68板条(简称Vitek2-GP68)、珠海迪尔生物工程有限公司链球菌板条(简称DL-STREP)和温州康泰生物科技有限公司链球菌板条(简称KT-STREP)进行体外药物敏感试验检测。采用分类一致性(CA)、基本一致性(EA)、极重要差异(VMD)和重要差异(MD)4个参数对体外药物敏感性试验结果进行评价。结果 青霉素MD值受解释标准的影响较大。4种板条中参与比对的其他药物(红霉素、复方磺胺甲噁唑、头孢噻肟、头孢曲松、美罗培南、克林霉素、左氧氟沙星、万古霉素、利奈唑胺)结果一致性较好,均达到了可接受标准(EA≥90%、CA≥90%、VMD<3%、MD<3%)。结论 除青霉素外,4种板条的体外药物敏感性试验结果一致性较好。

Abstract:

Objective To evaluate the consistency of 4 panels for in vitro drug susceptibility test of Streptococcus pneumoniae. Methods The concentration gradient method was used as a reference method. The in vitro drug susceptibility test was done with the SMIC panels of the American BD company's Phoenix100(BD-SMIC),the Vitek 2 Compact GP68 panels of French Bio Mérieux(Vitek 2-GP68),the Streptococcus panels of Zhuhai Deere Bioengineering Co.(DL-STREP) and the Streptococcus panels of Wenzhou Kangtai Biological Technology Co.,Ltd(KT-STREP). The results were evaluated by 4 parameters,including category agreement(CA),essential agreement(EA),very major discrepancy(VMD)and major discrepancy(MD). Results The MD values of penicillin were influenced by the interpretation criteria. Other drugs(erythromycin,trimethoprim-sulfamethoxazole,cefotaxime,ceftriazone,meropenem,clindamycin,levofloxacin,vancomycin and linezolid) involved in the comparison were acceptable(EA≥90%,CA≥90%,VMD<3% and MD<3%). Conclusions Except penicillin,the in vitro drug susceptibility test results of the 4 panels are consistent.

Key words: Streptococcus pneumoniae, In vitro drug susceptibility test, Consistency
