Discovering the means to control the increasing dissemination of pathogenic vibrios driven by recent climate change is challenged by the limited knowledge of the mechanisms in charge of Vibrio spp. persistence and spread in the time of global warming. To learn about physiological and gene expression patterns associated with the long-term persistence of V. harveyi at elevated temperatures, we studied adaptation of this marine bacterium in seawater microcosms at 30 °C which closely mimicked the… 

The Effect of the Environmental Temperature on the Adaptation to Host in the Zoonotic Pathogen Vibrio vulnificus

The results suggest that warm temperatures activate adaptive traits that would prepare the bacteria for host colonization and fish septicemia in a generalized manner, while environmental iron controls the expression of a host-adapted virulent phenotype.

Transcriptional responses to starvation of pathogenic Vibrio harveyi strain DY1

This is the first comprehensive transcriptomic analysis of starvation effects in V. harveyi, a pathogen of various aquatic organisms that has been recently associated with massive mortality episodes in the aquaculture industry.

Temperature Upshift Mostly but not Always Enhances the Growth of Vibrio Species: A Systematic Review

The spread of Vibrio spp. and the prevalence of vibriosis around the world are often correlated with global warming, especially an increase in sea surface temperature. However, many ecological and

A genome-wide association study of the occurrence of genetic variations in Edwardsiella piscicida, Vibrio harveyi, and Streptococcus parauberis under stressed environments.

The results presented in this study provide examples of possible molecular evolution in pathogens relevant to the aquaculture industry as a response to different environmental pressure.

Effect of sunlight and salinity on the survival of pathogenic and non‐pathogenic strains of Vibrio parahaemolyticus in water microcosms

In seawater under dark condition, Vibrio strains remain culturable for up to 200 days with a significant difference between strains (p < 0.05).

Genomic and Biological Profile of a Novel Bacteriophage, Vibrio phage Virtus, Which Improves Survival of Sparus aurata Larvae Challenged with Vibrio harveyi

In vivophage therapy trials in gilthead seabream, Sparus aurata, larvae demonstrated that Vibrio phage Virtus was able to significantly improve the survival of larvae for five days at a multiplicity of infection (MOI) of 10, which suggests that it can be an excellent candidate for phage therapy.

Revisiting CARD-FISH for Detection of Vibrio spp. in Natural Seawater

The results demonstrate that the use of the optimized protocol along with a very specific probe, ViB572a, can offer the high sensitivity and selectivity of CARD-FISH detection of marine vibrios in natural seawater.



Response of Vibrio cholerae to Low-Temperature Shifts: CspV Regulation of Type VI Secretion, Biofilm Formation, and Association with Zooplankton

It is shown that V. cholerae reprograms its transcriptome in response to fluctuations in temperature, which results in changes to biofilm formation and type VI secretion system activation, which impact environmental survival and the virulence potential of this pathogen.

Unveiling the Metabolic Pathways Associated with the Adaptive Reduction of Cell Size During Vibrio harveyi Persistence in Seawater Microcosms

In addition to triggering lipid degradation via the β-oxidation pathway and apparently promoting the use of endogenous fatty acids as a major energy and carbon source, V. harveyi upregulated genes involved in ancillary mechanisms important for sustaining iron homeostasis, cell resistance to the toxic effect of reactive oxygen species, and recycling of amino acids.

Changes in the Vibrio harveyi Cell Envelope Subproteome During Permanence in Cold Seawater

The proteomic study revealed that the level of membrane proteins playing key roles in cellular transport, maintenance of cell structure, and in bioenergetics processes remained unchanged along starvation at low temperature, thus suggesting that V. harveyi might need these proteins for the long-term survival and/or for the resuscitation process.

Survival strategies of Escherichia coli and Vibrio spp.: contribution of the viable but nonculturable phenotype to their stress-resistance and persistence in adverse environments

The characteristics of the VBNC state are discussed, its biological significance and contribution to bacterial survival are discussed and the bust and boom strategy is combined.

Ocean Warming and Spread of Pathogenic Vibrios in the Aquatic Environment

Vibrios are among the most common bacteria that inhabit surface waters throughout the world and are responsible for a number of severe infections both in humans and animals. Several reports recently

Environmental reservoirs and mechanisms of persistence of Vibrio cholerae

How V. cholerae can survive stressors such as starvation, temperature, and salinity fluctuations as well as how the organism persists under constant predation by heterotrophic protists is discussed.

Ecology of pathogenic and non-pathogenic Vibrio parahaemolyticus on the French Atlantic coast. Effects of temperature, salinity, turbidity and chlorophyll a.

Using generalized linear models, it is shown that the presence of V. parahaemolyticus in water could be explained by a combination of mean temperature over the 7 days before the day of sampling (P < 0.001) and turbidity (P = 0.058), and the importance of these ecological parameters is discussed.

Changes in marine prokaryotic community induced by varying types of dissolved organic matter and subsequent grazing pressure

A marked effect of DOM sources on the development of grazing-resistant prokaryotes is suggested after the addition of organic substrates, such as glucose, leucine and yeast extract, and the effect of grazing pressure exerted by nanoflagellates.
