Fig 1.

Dendrogram derived from the MALDI-TOF MS-specific protein signatures for strains with discordant identification results, including the profiles of S. warneri, S. pasteuri, S. epidermidis, and S. caprae from the MALDI Biotyper 3.0 database. Species names in this study defined by sodA sequence are shown after sample names. Additional species in parentheses are the discordant species identified by MALDI-TOF-based identification. Distance values were relative and normalized to a maximal value of 1,000.
