摘要
This report describes a short, on-plate formic acid (FA) extraction method for the identification of clinical yeast isolates using matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF MS). A total of 41.1% (78/190) and 63.7% (121/190) of yeasts were identified using species log score thresholds of > 2.0 and > 1.9, respectively. Overall, 97.4% (185/190) of yeasts were identified in combination with conventional FA extraction.
