PCR coupled with electrospray ionization mass spectrometry (PCR/ESI-MS) was compared with culture for pathogen detection in peritoneal dialysis (PD)-related peritonitis. Of 21 samples of PD effluent, PCR/ESI-MS identified microorganisms in 18 (86%) samples, including Mycobacterium tuberculosis in 1 culture-negative sample. Of 15 double-positive samples, PCR/ESI-MS and culture reached levels of agreement of 100% (15/15) and 87.5% (7/8) at the genus and species levels, respectively. PCR/ESI-MS can be used for rapid pathogen detection in PD-related peritonitis.
将聚合酶链反应(PCR)与电喷雾电离质谱法(PCR/ESI-MS)相结合,用于检测腹膜透析(PD)相关性腹膜炎的病原体,并与培养法进行比较。在21份PD流出液样本中,PCR/ESI-MS在18份(86%)样本中鉴定出微生物,其中1份培养阴性样本中检测出结核分枝杆菌。在15份双阳性样本中,PCR/ESI-MS与培养法在属水平和种水平的一致性分别达到100%(15/15)和87.5%(7/8)。PCR/ESI-MS可用于快速检测PD相关性腹膜炎的病原体。
