Abstract

Enterobacteria are the most frequent causative agents of sepsis. The spread of cephalosporinase- and carbapenemase-production in these species is a worrying threat for the effectiveness of the antibiotic therapy. Every hour saved in the detection of such strains can be crucial for the patients’ clinical outcome.

In this study, we investigate an innovative full MALDI-TOF MS based approach to quickly detect cephalosporinase- and carbapenemase-producing enterobacteria directly from the positive blood cultures bottles, applying the novel tools of the Biotyper system (Bruker Daltonik). The bacterial pellet extracted by Sepsityper was used for the species identification, for the detection of KPC-producing strains by subtyping, and for evaluation of cephalosporinase and carbapenemase activity by STAR-Cepha and STAR-Carba hydrolysis assays.
