Introduction: During the past few years, several studies describing direct identification of bacteria from bl cu ture using mass spectrometry have been published. These methods cannot, however, be easily integrated into a common laboratory workflow because of the hig hands-on time they require. In this paper, we propose a new method of identification with a short hands-or time and a turnaround time shorter than 15 min. Materials and methods: Positive blood bottles were homogenised and 600 ul. of blood were transferred to an Eppendorf tube 600 of buffer were added. homogenisation, a centrifugation of 4 min at 10,500g was performed nd the supernatant was discarded. The pellet was then washed and loaded in quadru plicate into wells of a Viteka MS-DS plate. Each well was covered with a saturated matrix solution and a MALDI mass spectrometry analysis was performed Species were identified using the software Myla 3.20.2. We analysed 266 blood bott A microorganism grew cultures. while five bottles Results: remained sterile after 48 h of incubation in subculture. our method reaches a probability of detection at the spe- cies level of 77.8 (203/261) with a positive predictive value of 99.5 (202/203) Conclusion: We developed a new method for the identification of microorganisms using mass spectrometry di rectly performed from a positive blood culture. This has short hands-on time and turnaround time and can easily take place in the workflow of a laboratory with comparable results in performance with other reported in the literature
