Abstract/Notes Abstract
Through the past decade, MALDI-TOF MS has been recognized as a fast and robust tool for identification of most bacteria in
clinical microbiology. However, the accuracy of this method to identify Neisseria species is still debated, and few data are
available about commensal Neisseria species identification. In this study, we assessed two MALDI-TOF MS systems (Bruker
Biotyper and Andromas) for the identification of 88, 18, and 29 isolates of Neisseria gonorrhoeae, Neisseria meningitidis, and
commensal Neisseria species, respectively. All 88 isolates of N. gonorrhoeae were correctly identified using both systems, and
most N. meningitidis and commensal Neisseria species were well identified: only 1/18 isolates of N. meningitidis was
misidentified using Bruker Biotyper, and 1 isolate of Neisseria polysaccharea was misidentified as N. meningitidis using both
systems. These results strengthen the possibility to use MALDI-TOF MS as a single method for Neisseria identification in
routine, with excellent performance for N. gonorrhoeae identification. However, results should be interpreted prudently for
N. meningitdis and commensal Neisseria species when isolated from genital and oropharyngeal samples where these both species
can coexist.
