Abstrakt: Background: Fast diagnosis of bloodstream infections remains the most important challenge for clinical microbiologists. The introduction of the mass-spectrometry represents a breakthrough, although several methods are already commonly used for the direct identification from positive blood cultures we present a faster method (ultra fast) for Lytic anaerobic flasks. Methods: We compare the ultra-fast (UF) method with the extensively employed differential centrifugation method (DC) and both to routine identification after 18-24 h of incubation. UF and DC method correlation rates to the gold standard were calculated, and statistical significance was proved with the Z test. Results: UF performed better overall than DC, with this difference being statistically significant. This tendency was observed in every subanalysis.
