() is a significant concern, as it can cause severe infections and hemolytic trauma. Given its prevalence in seawater and coastal seafood, it poses a substantial risk as a foodborne pathogen. Biosensor-based detection technology has been continuously evolving, and toehold switches have emerged as a promising area within it, especially in the detection of RNA viruses.

Gene regulation at the post-transcriptional level is prevalent in all domains of life. In bacteria, ProQ-like proteins have emerged as important RNA chaperones facilitating RNA stability and RNA duplex formation. In the major human pathogen Vibrio cholerae, post-transcriptional gene regulation is key for virulence, biofilm formation, and antibiotic resistance, yet the role of ProQ has not been studied.

Unlabelled: Bacteria have evolved diverse strategies to ensure survival under nutrient-limited conditions, where rapid energy generation is not achievable. Here, we performed a transposon insertion site sequencing loss-of-function screen to identify genes that promote pathogen fitness in stationary phase. We discovered that the aintenance of ipid symmetry (Mla) pathway, which is crucial for transferring phospholipids from the outer to the inner membrane, is critical for stationary phase fitness.

For successful infection, the life-threatening pathogen Vibrio vulnificus elaborately regulates the expression of survival and virulence genes using various transcription factors (TFs). In this study, a library of the V. vulnificus mutants carrying specific signature tags in 285 TF genes was constructed and subjected to 16 phenotypic analyses.

Enteric pathogens such as Vibrio cholerae are responsible for many deaths caused by contaminated food and water in these areas. While cholera is the prominent clinical threat posed by V.
