Outbreaks and mortality rates associated with this infection make it a significant public health concern. As biocontrol agents, probiotics such as Lactobacillus plantarum had been of interest for the promotion of antilisterial activities. However, a recent bacteriocin from epidemic L. monocytogenes strains called listeriolysin S (LLS) has been identifi...

In this study, we utilized a novel enrichment media containing activated charcoal as the key ingredient that induces hyperactive expression and secretion of L. monocytogenes virulence proteins. The Bio-Plex suspension array system, based on Luminex xMAP technology, was subsequently employed to specifically detect accumulated L. monocytogenes secreted and membrane bound proteins via paramagnetic microsphere-antibody complexes. Cantaloupe and packaged salad samples were treated with a dilution series of L. monocytogenes and incubated in activated charcoal media following a short pre-enrichment step in Buffered Listeria Enric...

The results showed that the...

Foodborne diseases (FBDs) are infections of the gastrointestinal tract caused by foodborne pathogens (FBPs) such as bacteria (Salmonella, Listeria monocytogenes and Shiga toxin-producing E. coli (STEC)) and several viruses, but also parasites and some fungi. Artificial intelligence (AI) and its sub-discipline machine learning (ML) are re-emerging and gaining an ever increasing popularity in the scientific community and industry, and could lead to actionable knowledge in diverse ranges of sectors including epidemiological investigations of FBD outbreaks and antimicrobial resistance (AMR). As genotyping using whole-genome se...

Abstract Contamination of food during processing is recognized as main transmission route of Listeria (L.) monocytogenes To prevent microbial contamination, biocides are widely applied as disinfectants in food processing plants. However, there are concerns about the development of antimicrobial resistance in foodborne pathogens due to widespread biocide usage.In our study, 93 L. monocytogenes isolates from German food production facilities were i) tested for biocide and antibiotic susceptibility using broth microdilution assays, ii) analyzed for links between reduced biocide susceptibility and antibiotic resistanc...
