MALDI-TOF质谱技术分析与鉴定病原细菌研究

Analysis and Identification of Pathogenic Bacteria by MALDI-TOF Mass Spectrometry

摘要:

本文通过基于基质辅助激光解吸电离飞行时间质谱(MALDI-TOF-MS)技术分析病原细菌的方法进行研究, 阐明影响分析结果的重要因素, 并建立了MALDI-TOF-MS 分析病原细菌的标准方法。对不同属、种和亚种的12株植物病原细菌进行全细胞分析结果表明：MALDI-TOF-MS能快速而准确的区分和鉴定病原细菌, 分析过程简单、灵敏度高。此法在细菌属、种、亚种和菌株水平上, 可快速、准确地区分和鉴定。

Abstract:

Based on Matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI- TOF-MS) method for discrimination of pathogenic bacteria was developed. Established the standardization method for MALDI-TOF-MS analysis of bacteria and affecting elements of the analyzing result. The results obtained from twelve plants pathogenic bacteria of different genus, species and subspecies were analyzed by using MALDI-TOF showed that, MALDI-TOF-MS could be rapid and reliable identification of bacteria at the level of genus, species, and strains. Analytical process is simple, high sensitivity are advantages of this strategy.
