Differentiation of <em>Listeria monocytogenes</em> strains

Listeria monocytogenes is a bacterial pathogen commonly associated with foodborne illnesses, posing a significant threat to public health. Bruker highlights the work of researchers at the laboratory of CVUA Stuttgart, Germany, who are employing Fourier transform infrared (FTIR) spectroscopy to differentiate Listeria monocytogenes strains based on their serogroups. This approach offers a rapid and cost-effective method for precise typing, aiding in the investigation of outbreaks and contamination routes in food processing. Through rigorous validation and testing, including external validation using established guidelines, the FTIR-based classifier demonstrates high accuracy in identifying serogroups, with potential implications for food safety and public health.
