The paper assesses the pathogenic potential of Vibrio isolates from Israel's coastal waters, finding toxin diversity, immune cell toxicity, and antibiotic resistance.

In vivo efficacy of L-ascorbic acid in restricting cholera pathogenesis

This study tests L-ascorbic acid's efficacy in reducing Vibrio cholerae bacterial load and accelerating recovery in rabbit models of cholera.

DNA repair is essential for Vibrio cholerae growth on Thiosulfate-Citrate-Bile Salts-Sucrose (TCBS) Medium

The paper shows that DNA repair is critical for Vibrio cholerae growth on TCBS agar, with DNA gyrase inhibition by bile acids mimicking fluoroquinolone effects.

Functional genomics of chitin degradation by Vibrio parahaemolyticus reveals finely integrated metabolic contributions to support environmental fitness

This study identifies key genetic factors in Vibrio parahaemolyticus that support chitin degradation and environmental fitness through Tn-seq and functional analysis.

Carbon source, cell density, and the microbial community control inhibition of V. cholerae surface colonization by environmental nitrate

This study shows that nitrite from V. cholerae nitrate respiration inhibits biofilm formation, but co-culturing with P. aminovorans reduces nitrite and enhances V. cholerae colonization.

The ecology of potentially pathogenic Vibrio spp. in a seagrass meadow ecosystem

This study examines Vibrio spp. abundance and ecology in Baltic Sea seagrass meadows, finding higher concentrations in water above unvegetated areas and on seagrass roots.

A connection between Vibrio cholerae motility and inter-animal transmission

This study shows that reduced motility in Vibrio cholerae decreases inter-animal transmission, while increased motility enhances transmission efficiency in mice.

Vibrio cholerae RbmB is an α-1,4-polysaccharide lyase with biofilm-dispersal activity against Vibrio Polysaccharide (VPS)

This study identifies RbmB as a polysaccharide lyase that cleaves Vibrio cholerae VPS, contributing to biofilm dispersal and suggesting its potential as an antibacterial enzyme.

Bacterial Modulation of Intestinal Motility through Macrophage Redistribution

This study shows that Vibrio cholerae's T6SS ACD induces intestinal contractions by activating macrophages and altering their distribution in zebrafish.

Vibrio cholerae CsrA controls ToxR levels by increasing the stability and translation of toxR mRNA

This paper shows that CsrA directly increases ToxR levels in Vibrio cholerae by stabilizing and enhancing translation of toxR mRNA through binding to its 5 UTR.

Expression pattern of the ST heat-stable enterotoxin gene cassettes in Vibrios superintegrons

The paper examines the expression and genomic context of the ST heat-stable enterotoxin gene in Vibrio species, finding differential expression linked to promoter variations.

Vibrio mimicus carrying the Type III Secretion System 2 (T3SS2) and TDH toxin of Vibrio parahaemolyticus in an integrative conjugative element context

The paper identifies T3SS2 and TDH/TRH toxins from Vibrio parahaemolyticus in Vibrio mimicus genomes, associated with an integrative conjugative element that may spread virulence factors.

Bile acids activate the antibacterial T6SS1 in the gut pathogen Vibrio parahaemolyticus

This study shows that secondary bile acids activate T6SS1 in Vibrio parahaemolyticus, enabling it to kill commensal bacteria and enhance its virulence.

Detection of Potential Phytochemicals against ctxAB Toxin to Combat Cholera

This study identifies two phytochemicals, Limonin and Emodin, that may inhibit cholera toxin B subunit binding to host mucosa through molecular docking and simulation analyses.

Type VI Secretion Promotes Microbial Antagonism and Contributes to Pathogenesis by AHPND-causing Vibrio parahaemolyticus

This study shows that Type VI Secretion Systems (T6SS) in AHPND-causing Vibrio parahaemolyticus enhance microbial antagonism and virulence in shrimp.

Pandemic Vibrio cholerae Acquired Competitive Traits from an Environmental Vibrio Species

The paper identifies V. anguillarum as a source of T6SS effectors acquired by pandemic V. cholerae through horizontal gene transfer.

Genomic characteristics of recently recognized Vibrio cholerae El Tor lineages associated with cholera in Bangladesh, 1991-2017

The paper performs a genomic analysis of Vibrio cholerae El Tor strains from Bangladesh, identifying two lineages, BD-1 and BD-2, and their distinct genomic traits and epidemiological implications.

Vibrio cholerae El Tor strains linked to global cholera are homogeneous by pulsed-field gel electrophoresis

The paper uses PFGE to analyze V. cholerae El Tor strains from Bangladesh and other countries, finding most pandemic strains belong to a major clade with distinct geographic lineages.

Integrated metabolic modeling, culturing and transcriptomics explains enhanced virulence of V. cholerae during co-infection with ETEC

This study uses genome-scale metabolic models and co-culture experiments to show that V. cholerae grows better and is more virulent during co-infection with ETEC due to metabolic cross-feeding.

Genomic analysis of pathogenic isolates of Vibrio cholerae from eastern Democratic Republic of the Congo (2014-2017)

This study analyzes genomic data from Vibrio cholerae isolates in eastern DRC to identify genetic clusters and their geographic spread across neighboring countries.

Nanopore long reads enable the first complete genome assembly of a Malaysian Vibrio parahaemolyticus isolate bearing the pVa plasmid associated with acute hepatopancreatic necrosis disease

The paper uses Nanopore long reads to assemble the first complete genome of a Malaysian Vibrio parahaemolyticus isolate with the pVa plasmid, revealing new genomic features linked to pathogenicity.

Backward compatibility of whole genome sequencing data with MLVA typing using a new MLVAtype shiny application: the example of Vibrio cholerae

The paper introduces MLVAType, a tool that extracts MLVA profiles from WGS data while maintaining compatibility with traditional MLVA methods, and identifies limitations in k-mer size affecting accuracy.
