Abstract:
... Campylobacter jejuni is a globally important foodborne pathogen that can exist environmentally in a viable but non-culturable (VBNC) state, leading to missed detection of VBNC cells in food and false results in epidemiological surveillance. To establish a method for its resuscitation from the VBNC state and enable better detection, the mechanisms by which C. jejuni are induced into the VBNC state ...

Abstract:
... FraR, a transcriptional repressor, was postulated to regulate the metabolism of the Amadori compound fructose-asparagine (F-Asn) in the foodborne pathogen Salmonella enterica. Here, the DNA- and inducer-binding affinities and stoichiometries of FraR were determined and cross-validated by electrophoretic mobility-shift assays (EMSAs) and online buffer exchange coupled to native mass spectrometry (O ...

Abstract:
... Bacterial microcompartments (BMCs) are protein-based organelles that enhance a variety of metabolic functions in diverse bacteria and recent studies unveiled the importance of BMCs in bacterial adaptation from foods to gut. Comparative whole genome sequencing has shown a broad distribution of BMC-dependent metabolic pathways, but studies addressing the role of BMCs in food-related microbes are sca ...

Abstract:
... Listeria monocytogenes is a foodborne pathogen that can form biofilms in food processing facilities even under unfavorable growth environment. This study aimed to evaluate the biofilm eradication ability of Listeria-specific bacteriophage (phage) cocktail (LMPC01+02+03) against L. monocytogenes young (1 day) and mature (3 days) biofilms formed on food contact materials (FCMs: polyethylene, polypro ...

Abstract:
... Food-processing facilities harbor a wide diversity of microorganisms that persist and interact in multispecies biofilms, which could provide an ecological niche for pathogens to better colonize and gain tolerance against sanitization. Biofilm formation by foodborne pathogens is a serious threat to food safety and public health. Biofilms are formed in an environment through synergistic interactions ...

Abstract:
... Shiga toxin‐producing Escherichia coli (STEC) is an important food‐borne pathogen capable of causing severe gastrointestinal diseases in humans. Cattle and sheep are the natural reservoir hosts of STEC strains. Previously, we isolated 56 STEC strains from anal and carcass swab samples of cattle and sheep in farms and slaughterhouses. In this study, we performed whole‐genome sequencing of these iso ...
