High Awareness, Poor Practice: The Cholera Prevention Knowledge‐Attitude‐Practice Gap in Ada Foah, Ghana—A Cross‐Sectional Study

Public Health Challenges, Volume 5, Issue 3, September 2026.
ABSTRACT Background Cholera persists as a public health threat in Ghana, particularly in coastal communities with inadequate water, sanitation and hygiene (WASH) infrastructure. This study assessed the knowledge, attitudes and practices (KAP) toward cholera among residents of Ada Foah, a high‐risk coastal district in Ghana, to identify gaps and inform ...

Structure‐Guided Engineering of a Ser192Ala Variant Enhances Bidirectional Catalysis in Amycolatopsis sulphurea L‐Alanine Dehydrogenase

ChemCatChem, Volume 18, Issue 15, 14 August 2026.
A rationally engineered Ser192Ala variant of Amycolatopsis sulphurea L‐alanine dehydrogenase (L‐AlaDH) exhibits ∼2‐fold higher catalytic efficiency in both reductive amination and oxidative deamination. Experimental characterization confirms maintained stability under tested conditions, highlighting its potential as an improved biocatalyst for ...

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 ...

Identification of Atypical El TorV. cholerae O1 Ogawa Hosting SXT Element in Senegal, Africa [PDF]

Frontiers in Microbiology, 2017
Vibrio cholerae O1 is the causative agent of cholera with classical and El Tor, two well-established biotypes. In last 20 years, hybrid strains of classical and El Tor and variant El Tor which carry classical ctxB have emerged worldwide. In 2004-2005, Senegal experienced major cholera epidemic with a number of cases totalling more than 31719 with ...

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.

Type III Secretion Is Essential for the Rapidly Fatal Diarrheal Disease Caused by Non-O1, Non-O139 Vibrio cholerae

mBio, 2011
Cholera is a severe diarrheal disease typically caused by O1 serogroup strains of Vibrio cholerae. The pathogenicity of all pandemic V. cholerae O1 strains relies on two critical virulence factors: cholera toxin, a potent enterotoxin, and toxin ...

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.
