title: Species identification of Streptococcus bovis group isolates causing bacteremia: a comparison of two MALDI-TOF MS systems.
abstract: This study compared two MALDI-TOF MS systems (Biotyper and VITEK MS) on clinical Streptococcus bovis group isolates (n=66). The VITEK MS gave fewer misidentifications and a higher rate of correct identifications than the Biotyper. Only the identification of S. lutetiensis by the VITEK MS was reliable. Additional optimization of the available system databases is needed.
