Chasing listeria in food and water: Advancements in detection and strain discrimination

In this application note, Bruker's listeria workflow showcases the MALDI Biotyper's^® ability to identify microorganisms by their proteomic fingerprints. Additionally, the IR Biotyper^® serves as a rapid microbiological method for strain discrimination, offering ready-to-use classifiers that are valuable for typing L. monocytogenes based on colony material. The IR Biotyper is not limited to L. monocytogenes alone, supporting various other species and allowing users to test their own strain collections. This flexibility extends to constructing dendrograms and scatter plots for strain discrimination across Gram-positive and Gram-negative bacteria.
