Abstract
- Importance: Given the involvement of Vibrio parahaemolyticus ( Vp ) in a wide range of seafood outbreaks, a systematical characterization of Vp fitness and transcriptomic changes at temperatures of critical importance for seafood production and storage is needed. In this study, one of each virulent Vp strain ( tdh + and trh +) was tested. While no difference in survival behavior of the two virulent strains was observed at 10°C, the tdh + strain had a faster growth rate than the trh + strain at 30°C. Transcriptomic analysis showed that a significantly higher number of genes were upregulated at 30°C than at 10°C. The majority of differentially expressed genes of Vp at 30°C were annotated to functional categories supporting cellular growth. At 10°C, the downregulation of the biofilm formation and histidine metabolism indicates that the current practice of storing seafood at low temperatures not only protects seafood quality but also ensures seafood safety.<br />Competing Interests: The authors declare no conflict of interest.
