DNAJC5 and listeriosis: Overall, the data generated from these assays might provide valuable insights in the development and application of novel treatment and disinfection protocols against Lm. Identification of chemicals under which the csp deletion mutants outperformed the WT, e.g., ketoprofen can be exploited in the search for new antimicrobials and/or in listeriosis patients requiring drugs with analgesic and antipyretic effects.
