摘要:

目的 评价基质辅助激光解析电离飞行时间质谱(Matrix-Assisted Laser Desorption Ionization-Time Of Flight-Mass Spectrometry,MALDI-TOF-MS)技术对酵母样真菌鉴定的临床应用价值。方法 将2015年6月~2016年6月临床检出的142株酵母样真菌标本同时采用MALDI-TOF-MS技术和传统真菌培养方法进行鉴定,记录结果并对结果进行对比分析。结果 两种方法对于常见的白念珠菌、热带念珠菌、克柔念珠菌和新生隐球菌的鉴定率很高(100%),符合率较高(100%);对于少见的葡萄牙念珠菌、解脂念珠菌、产朊念珠菌,两种方法的符合率较低,分别为25.00%、00.00%、00.00%。结论 MALDI-TOF-MS技术对酵母样真菌的鉴定率较高,操作简便快速,是传统真菌培养鉴定的有力补充,可将其推广应用于酵母样真菌的早期快速鉴定。

Abstract:

Objective MALDI-TOF-MS technology was evaluated the clinical application value of MALDI-TOF-MS in the rapid identification of yeast-like fungi.Methods MALDI-TOF-MS technology and traditional fungi cultural method were used to identify 142 yeast-like fungi of clinical isolates which from June 2015 to June 2016,results were recorded and analyzed.Results The rate of identification of two methods for common C.albicans,C.tropical,C.krusei and Cryptococcus neoformans were very high (100%),concordant rate was 100%;The rate of identification of two methods for uncommon C.lusitaniae,C.lipolytica and C.utilis were very low,concordant rate were 25.00%,00.00% and 00.00% respectively.Conclusion MALDI-TOF-MS had a better identification rate of yeast-like fungi,and the characteristic of simple and rapid operation provided a powerful complement for traditional manual method,which could be applied in the early rapid identification of yeast-like fungi.

Key words: MALDI-TOF-MS, yeast-like fungi, detection
