Abstract
Objective To probe into the superiority of MALDI-TOF MS in the identification of clinical yeast to provide the basis for early diagnosis and treatment of clinical fungal infection.Methods A total of 206 strains of yeast clinically isolated in our hospital from August 2015 to March 2016 were collected and identified with MALDI-TOF mass spectrometer,VITEK2 compact microbial analyzer and chromogenic culture respectively.The ITS sequencing results were used as the final confirmation one.The accuracies of identifying yeast were compared among these 3 kinds of method.Results The accuracy rates of 3 kinds of method for identifying yeast were 82.5% for VITEK2 Compact,67.0% for chromogenic method and 92.7% for MALDI-TOF mass spectrometry.The difference between MALDI-TOF and VITEK2 compact was statistically significant(P=0.006),and the difference between MALDI-TOF and chromogenic method was statistically significant(P=0.001).Conclusion Compared with the VITEK2 Compact microbial analyzer and the color developing method,the MALDI-TOF mass spectrometer has the advantages of rapidness,simple operation,accurate results and so on.关键词
