Article Synopsis
- The study investigates various typing methods for Staphylococcus aureus to determine the best approach for epidemiological investigations and outbreak analysis.
- Methods compared included PFGE, MLST, cgMLST, cSNP, and enterotoxin profiling on 351 S. aureus isolates, assessing their discriminatory power and reliability.
- Results showed that cgMLST and cSNP performed best in distinguishing strains and resolving population structure, while all methods effectively identified related strains in outbreak scenarios.
Article Synopsis
- Shotgun metagenomics helps find germs in food quickly, but usually needs extra steps to grow the germs first, which can mess up the results.
- Researchers tried a new method called adaptive sampling to avoid growing the germs and just focus on what they want to find in food samples.
- The new method worked better than the old way and helped scientists identify dangerous germs more accurately, making it faster to solve food safety problems.
Cereulide is an emetic toxin produced by some strains of . This bacterial toxin, a cyclic 1.2 kDa dodecadepsipeptide, is stable to heat and acids and causes nausea and vomiting when ingested via contaminated food.

In this study, we retrospectively characterized viable () isolates originating from commercial vitamin B feed and food additives collected between 2016 and 2022 by the Belgian Federal Agency for the Safety of the Food Chain from products sold on the Belgian market. In total, 75 collected product samples were cultured on a general medium and, in case of bacterial growth, two isolates per product sample were collected and characterized using whole-genome sequencing (WGS) and subsequently characterized in terms of sequence type (ST), virulence gene profile, antimicrobial resistance (AMR) gene profile, plasmid content, and phylogenomic relationships.
