Positive blood bottles were homogenised and 600 μL of blood were transferred to an Eppendorf tube where 600 μL of lysis buffer were added. After homogenisation, a centrifugation step of 4 min at 10,500g was performed and the supernatant was discarded. The pellet was then washed and loaded in quadruplicate into wells of a Vitek® MS-DS plate. Each well was covered with a saturated matrix solution and a MALDI-TOF mass spectrometry analysis was performed. Species were identified using the software Myla 3.2.0-2.
