Summary: The potential spread of infectious diseases in response to climate change and rising sea surface temperatures in temperate regions has raised concerns over the past few decades. Different species of Vibrio, particularly Vibrio cholerae, Vibrio parahaemolyticus, and Vibrio vulnificus, have been correlated with human health risks in relation to extreme heat waves in the North Atlantic and North Sea regions. Studying the behavior and ecology of both pathogenic and non-pathogenic strains of these bacteria can provide insights into their native microbiome and how they disperse in coastal regions.

Summary: Recent studies suggest that the presence of Paracoccus aminovorans, a commensal bacterium, in the human intestine may enhance the colonization of Vibrio cholerae. The interaction between the two species was shown to form a dual-species biofilm structure with novel features, and this interaction was found to be dependent on the Vibrio exopolysaccharide and other major components of mature V. cholerae biofilm. These findings demonstrate that multispecies biofilm formation could be a mechanism used by gut microbes to increase the virulence of pathogens and potentially impact the outcomes of enteric infections.

Summary: Zebrafish provide an attractive model for studying host-microbe interactions, with the core intestinal microbiome primarily consisting of Proteobacteria. Vibrio cholerae can significantly alter the zebrafish intestinal microbiome, with different strains inducing varying changes. Specific microbes targeted by V. cholerae for colonization in zebrafish hosts depend on the genotype of the V. cholerae strain.

Summary: Vibrio cholerae, the causative agent of cholera, forms symbiotic associations with aquatic arthropods to facilitate its environmental persistence and dissemination. The dynamics of interactions between V. cholerae and aquatic arthropods remain largely unknown. This study developed a new experimental host system using chironomid larvae to investigate the effects of bacterial cell density and strain on V. cholerae-chironomid interactions. The findings highlight the importance of cell density in determining V. cholerae invasion success in chironomid larvae and provide insights into V. cholerae-arthropod interactions using a novel approach.

Summary: The cell wall of most bacteria, composed of peptidoglycan, plays a crucial role in protecting them from environmental stressors. Vibrio cholerae has become a major model for studying cell wall genetic determinants, regulatory links, and adaptive mechanisms, shedding light on novel insights. This review provides a comprehensive overview of V. cholerae's cell wall biology and genetics, emphasizing the similarities and differences with Escherichia coli.

Summary: Zebrafish are a popular model organism for studying host-microbe interactions, and Vibrio cholerae infections significantly modulate the zebrafish intestinal microbiome, with the type six secretion system (T6SS) playing a crucial role in inducing mucin secretion and pathogenesis. Different strains of V. cholerae, with or without T6SS, lead to distinct changes in the composition and structure of the intestinal microbiome, highlighting the importance of T6SS in altering host microbial profiles.

Summary: CsrA is a critical posttranscriptional global regulator in Vibrio cholerae, controlling 22% of the bacterial transcriptome involving various cellular processes. Through RNA coimmunoprecipitation experiments, it was found that CsrA binds to multiple mRNAs encoding regulatory proteins, including major sigma factors. Additionally, CsrA directly binds to virulence gene transcripts, positively regulating the production of important virulence factors.

Summary: Colibactin, a secondary metabolite encoded by the pks gene island in pathogenic Escherichia coli, may cause DNA damage and tumorigenesis. However, fundamental knowledge about colibactin's function is still lacking, and further research is needed to elucidate the biological mechanisms governing production and delivery of this compound by these bacteria.

Summary: This study reveals that the VC1795 gene plays a key role in the intestinal colonization and pathogenicity of Vibrio cholerae, and it regulates the expression of its downstream gene, VC1794, and the toxin-coregulated pilus (TCP) cluster. These findings provide insights into the regulatory mechanisms of VC1795 in bacterial pathogenesis.

Summary: Horizontal gene transfer is a key driver of bacterial evolution, facilitated by mobile genetic elements such as plasmids and bacteriophages. This study identifies two conserved plasmid defence systems in Vibrio cholerae, responsible for the ongoing cholera pandemic. These systems rapidly eliminate small plasmids and defend against bacteriophage infection. Additionally, they increase the burden of large conjugative plasmids, leading to a fitness disadvantage for plasmid-carrying cells. These findings explain the rarity of plasmids in pandemic strains and have implications for understanding antibiotic resistance plasmid dissemination and the evolution of pandemic V. cholerae.

Summary: In this study, it was found that cassette recruitment in the Vibrio cholerae chromosomal integron mainly occurs at the attIA site, with newly inserted cassettes being expressed and selected due to the presence of a promoter in the vicinity of this site. The RecA protein plays a critical role in this process, but the V. cholerae integron integrase is not active in other bacteria.

Summary: The rise in vibriosis cases and the importance of surveillance of toxigenic Vibrio cholerae strains are emphasized due to climate events and ocean warming. Traditional phenotyping using antisera against O1 and O139 is limited for non-O1/non-O139 strains. Whole-genome sequencing analysis and phylogenetic methods were used to investigate a nonagglutinating strain and its relationship to other strains recovered from vibriosis cases.

Summary: Biofilms are a growth mode in which microbial communities are structured and embedded in a polymeric extracellular matrix. In this study, the biofilm formation of Vibrio cholerae is focused and the current understanding of its formation, including attachment, matrix components, dynamics, regulation, and dispersal, is summarized. The decision to form or disperse from biofilms is regulated by a complex network that integrates various environmental inputs.

Summary: Escherichia coli Nissle 1917 is a Gram-negative bacterium used for treating inflammatory bowel diseases, with its ability to produce secondary metabolites playing a key role in its activity. The APE biosynthetic gene cluster and the interaction between acyl carrier proteins and phosphopantetheinyl transferase (PPTase) in EcN are essential for understanding its function. This knowledge is crucial for engineering secondary metabolite production hosts and targeting PPTases with new antibiotics.
