The dilemma of identifying Peptoniphilus species by using two MALDI-TOF MS systems

Claudia Barberis et al. Anaerobe. 2022 Feb.

Abstract

Two commercial MALDI-TOF MS systems were used to identify 18 isolates, belonging to the Peptoniphilus genus; also the 16S rRNA sequencing identity was compared against the MALDI-TOF MS system results. Bruker Biotyper system provided higher accuracy than Vitek MS system, however, adding spectra could allow a more reliable species level identification.
