| Abstract: | MALDI-TOF-MS systems (Microflex-Bruker Daltonics/BioTyper? and Axima-Assurance-Shimadzu/SARAMIS-AnagnosTec) were assessed for bacterial identification. Focusing on bacteria difficult to identify routinely, 296 strains were identified by molecular biology techniques as gold standard. MALDI-TOF-MS identification provided correct results at genus and species level for 94.9%, 83.4% and 83.8%, 65.9% with Biotyper and Saramis respectively. |
