摘要 肺炎克雷伯菌(Klebsiella pneumoniae,KP)是社区获得感染、医院内获得感染的重要病原菌之一,且耐碳青霉烯类肺炎克雷伯菌(carbapenem-resistant Klebsiella pneumoniae,CRKP)的感染呈逐年上升[1],给临床诊治带来了极大挑战。研究发现,黄连素能较好地抑制CRKP的生长,并且有逆转CRKP耐药性的作用[2]。基于此,本研究拟采用基质辅助激光解吸电离飞行时间质谱仪(matrix-assisted laser desorption ionization time-of-flight mass spectrometry,MALDI-TOF MS)对黄连素作用前后CRKP进行分析,评估黄连素作用后细菌蛋白质峰谱的改变。
