Rapid Subtyping of Yersinia enterocolitica by Matrix-Assisted Laser Desorption Ionization–Time of Flight Mass Spectrometry (MALDI-TOF MS) for Diagnostics and Surveillance

In this study, an alternative to the current traditional bioserotyping techniques was developed for subtyping Y. enterocolitica using matrix-assisted laser desorption ionization–time of flight mass spectrometry (MALDI-TOF MS). The most common pathogenic bioserotypes could easily be distinguished using only a few bioserotype-specific biomarkers. However, biochemical methods should still be used to distinguish biotype 1A from 1B.
