摘要：

Introduction: Matrix-Assisted Laser Desorption-Ionisation Time-of-Flight (MALDI-TOF) Mass Spectrometry is rapid and accurate for the bacterial identification. Methods: We have evaluated a less laborious and less time consuming method for microorganism identification directly from positive blood cultures. Results: When we considered the scores >= 1.7 and >= 1.4 for acceptable identification of species and genus, the percentage of identification was 77.5% and 93.9%, respectively. Conclusions: This method is reliable, rapid and cost-effective for implementation in routine use in clinical microbiology laboratories. (C) 2012 Elsevier Espana, S.L. All rights reserved.
