Vibrio parahaemolyticus is a shellfish-borne pathogen that is a highly prevalent causative agent of inflammatory gastroenteritis in humans. Genomic libraries have proven useful for the identification of novel gene functions in many bacterial species.

The bacterium Vibrio coralliilyticus has been implicated in mass mortalities of corals and shellfish larvae. However, using corals for manipulative infection experiments can be logistically difficult compared to other model organisms, so we aimed to establish oyster larvae infections as a proxy model.

Vibrio cholerae O1 and O139 isolates deploy cholera toxin (CT) and toxin-coregulated pilus (TCP) to cause the diarrhoeal disease cholera.

Bdellovibrio and like organisms (BALOs) are a group of Gram-negative bacteria that prey on other Gram-negative bacteria.

Vibrio cholerae the causative agent of cholera, uses a large number of coordinated transcriptional regulatory events to transition from its environmental reservoir to the host intestine, which is its preferred colonization site.

Introduction. The Philippines, comprising three island groups, namely, Luzon, Visayas and Mindanao, experienced an increase in cholera outbreaks in 2016.

During the 1854 cholera outbreak in Florence, Italy, Filippo Pacini documented that the cause of the infection was a bacterium. This conclusion was also independently reached by John Snow during the 1854 cholera outbreak in London. By using an epidemiological method, Snow found that the infection spread through a polluted water network. Snow identified a water pump as the source of the disease. After removing the infected handle of this pump, the cases of cholera rapidly began to decrease.

We investigated the evolution, phylogeny and antimicrobial resistance of Vibrio cholerae O1 isolates (VCO1) from Ghana.

Vibrio cholerae the causative agent of cholera, uses a large number of coordinated transcriptional regulatory events to transition from its environmental reservoir to the host intestine, which is its preferred colonization site.

Vibrio cholerae O1 is the aetiological agent of the severe diarrhoeal disease cholera. Annually, there are an estimated 1–4 million cholera cases worldwide and over 140 000 deaths. The primary mode of disease transmission is through the consumption of water or food contaminated with the bacterium.

Consumption of prawns as a protein source has been on the rise worldwide with seafood identified as the predominant attributable source of human vibriosis. However, surveillance of non-cholera Vibrio is limited both in public health and in food.

Vibrio species are important environmental-related bacteria responsible for diverse infections in humans due to consumption of contaminated water and seafood in underdeveloped areas of the world.

Specific lineages of serogroup O1 Vibrio cholerae are notorious for causing cholera pandemics, of which there have been seven since the 1800s. Much is known about the sixth pandemic (1899–1923) and the ongoing seventh pandemic (1961–present), but we know very little about the bacteriology of pandemics 1 to 5.

Members of the bacterial genus Vibrio utilize chitin both as a metabolic substrate and a signal to activate natural competence.

The virulence of Vibrio parahaemolyticus is variable depending on its virulence determinants. A V.

Despite the recent advances in sequencing technologies, the complete assembly of multi-chromosome genomes of the Vibrionaceae , often containing several plasmids, remains challenging.

Introduction. Cholix toxin (ChxA) is an ADP-ribosylating exotoxin produced by Vibrio cholerae .

Many strains of lactic acid bacteria have been used for the production of probiotics. Some metabolites produced by lactic acid bacteria impair the motilities of pathogenic bacteria. Because bacterial motility is strongly associated with virulence, the metabolic activities of lactic acid bacteria are effective for suppressing bacterial infections. Here we show that lactose fermentation by Lactococcus lactis subsp. lactis inhibits the motility of Salmonella enterica serovar Typhimurium.
