Host Factor Induced Bacterial Extracellular Vesicles Promote Horizontal Gene Transfer in Vibrio cholerae

Journal of Extracellular Vesicles, Volume 15, Issue 5, May 2026.
Antimicrobial stressors, that is, bile or mitomycin C, induce enlarged, nucleic acid‐rich bacterial extracellular vesicles in Vibrio cholerae that facilitate horizontal gene transfer in vitro and during intestinal colonisation. The findings provide a detailed comparison of control versus stress‐induced vesicles, identify bile as a host factor shaping ...

Role of the P plasmid in attenuation of Vibrio cholerae O1 [PDF]

Infection and Immunity, 1990
The conjugative plasmid P of Vibrio cholerae has been shown to have a suppressive effect on the virulence of hypertoxigenic strains like 569B. In this study, we have sought to analyze this phenomenon. Utilizing the infant mouse cholera model, we have demonstrated that the presence of P increases the 50% lethal dose of V.

Phosphate Limitation Modulates Vibrio Cholerae Outer Membrane Vesicle Formation, Composition and Toxicity

Journal of Extracellular Biology, Volume 5, Issue 5, May 2026.
ABSTRACT Vibrio cholerae inhabits phosphorus‐poor aquatic environments and host intestine, where it expresses genes regulated by the PhoB/PhoR two‐component system in response to inorganic phosphate (Pi) limitation. Like other Gram‐negative bacteria, V.

Hybrid Vibrio cholerae El Tor Lacking SXT Identified as the Cause of a Cholera Outbreak in the Philippines

mBio, 2015
Cholera continues to be a global threat, with high rates of morbidity and mortality. In 2011, a cholera outbreak occurred in Palawan, Philippines, affecting more than 500 people, and 20 individuals died.

Pandemic Vibrio cholerae and the Environmental Reservoir Hypothesis—Outstanding Questions Central to Global Cholera Control

Environmental Microbiology, Volume 28, Issue 5, May 2026.
Whether, when and for how long pandemic Vibrio cholerae forms long‐term environmental reservoirs remains uncertain. We propose a new framework to evaluate possible mechanisms by which the pathogen might experience reservoir formation versus environmental elimination.

Assessment of the Incidence of Vibrio spp. in Shrimp Farms Relative to Water Parameters and Their Molecular Detection in the Southwest Coastal Region of Bangladesh

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
There was no significant relation between the incidence of Vibrio spp. and water parameters, except ammonium in the winter season. In this study, 48.02% (85/177) isolates were positive for Vibrio cholerae, 51.97% (92/177) for Vibrio parahaemolyticus, 15.21% (14/92) for trh gene, and 6.52% (6/92) for tdh gene.

A Fluorogenic Biosensor for Direct Detection of Vibrio vulnificus, a Climate Change Biomarker

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
Nanoporous anodic alumina (S2) loaded with rhodamine B and capped with a specific oligonucleotide probe (O1) for the vvhA gene. In the presence of V. vulnificus genomic DNA, probe displacement opens the pores and releases the dye, generating a measurable fluorescent signal.

Risk assessment of the production of seaweed in the Netherlands; food safety and nature

Food Risk Assess Europe, Volume 4, Issue 2, April 2026.
Abstract Seaweed is seen as an important source of alternative proteins for a sustainable food system and food security. The cultivation of seaweed is therefore encouraged by the European Union (EU) and also by the Dutch government.In the Netherlands, seaweed is farmed on small scale in the Southwest Delta, the Wadden Sea and the North Sea. Despite the

Growth of Vibrio cholerae O1 Ogawa Eltor in freshwater [PDF]

Microbiology, 2007
Growth of Vibrio cholerae O1 Ogawa Eltor was studied with a growth assay in which autoclaved and filtered (0.22 microm) freshwater was inoculated at low cell density (5 x 10(3) cells ml(-1)) and proliferation was followed with flow cytometry. Against the common view, V. cholerae was able to grow extensively in different kinds of freshwater.
