“…In contrast, presence of V. vulnificus was mainly restricted to sites within the Ems and Weser estuaries with mean salinities of ∼4 to 17 psu, and V. vulnificus abundance in the study area was significantly related to low salinity. These findings reveal a preference of V. vulnificus for brackish waters, supporting earlier descriptions as an estuarine bacterium [11]. The present study showed, however, that V. vulnificus can occasionally occur at sites with high mean salinities that are usually not expected to be within the range tolerated by this bacterium.…”

“…At least 12 species of the Vibrio genus are potentially pathogenic to humans [1]. Particularly Vibrio parahaemolyticus and Vibrio vulnificus, but also Vibrio alginolyticus and Vibrio cholerae are known as causative agents of seawater-related illnesses, such as seafood poisoning in association with gastrointestinal infections [2][3][4] and infections of wounds and mucous membranes [5][6][7][8][9][10][11].…”

The number of reported Vibrio-related wound infections associated with recreational bathing in Northern Europe has increased within the last decades. In order to study the health risk from potentially pathogenic Vibrio spp. in the central Wadden Sea, the seasonal and spatial distribution of Vibrio vulnificus, Vibrio parahaemolyticus, Vibrio alginolyticus and Vibrio cholerae were investigated at ten recreational beaches in this area over a 2-year period. V. alginolyticus and V. parahaemolyticus were found to be omnipresent all year round in the study area, while V. vulnificus occurrence was restricted to summer months in the estuaries of the rivers Ems and Weser. Multiple linear regression models revealed that water temperature is the most important determinant of Vibrio spp. occurrence in the area. Differentiated regression models showed a species-specific response to water temperature and revealed a particularly strong effect of even minor temperature increases on the probability of detecting V. vulnificus in summer. In sediments, Vibrio spp. concentrations were up to three orders of magnitude higher than in water. Also, V. alginolyticus and V. parahaemolyticus were found to be less susceptible towards winter temperatures in the benthic environment than in the water, indicating an important role of sediments for Vibrio ecology. While only a very small percentage of tested V. parahaemolyticus proved to be potentially pathogenic, the presence of V. vulnificus during the summer months should be regarded with care.

“…Vibrios are Gram-negative, curved, rod-shaped bacteria belonging to the class Gammaproteobacteria and are still regarded by most marine microbiologists as the dominant culturable bacteria in the ocean (Pruzzo et al, 2005). They are found on a number of biotic and abiotic substrates, notably associated with chitinous plankton, which is considered to be an important reservoir of these bacteria in nature (Colwell, 1996;Turner et al, 2009).…”

Long-term effects of ocean warming on the prokaryotic community: evidence from the vibrios

The long-term effects of ocean warming on prokaryotic communities are unknown because of lack of historical data. We overcame this gap by applying a retrospective molecular analysis to the bacterial community on formalin-fixed samples from the historical Continuous Plankton Recorder archive, which is one of the longest and most geographically extensive collections of marine biological samples in the world. We showed that during the last half century, ubiquitous marine bacteria of the Vibrio genus, including Vibrio cholerae, increased in dominance within the planktonassociated bacterial community of the North Sea, where an unprecedented increase in bathing infections related to these bacteria was recently reported. Among environmental variables, increased sea surface temperature explained 45% of the variance in Vibrio data, supporting the view that ocean warming is favouring the spread of vibrios and may be the cause of the globally increasing trend in their associated diseases.

Vibrio species are both ubiquitous and abundant in marine coastal waters, estuaries, ocean sediment, and aquaculture settings worldwide. We report here the isolation, characterization, and genome sequence of a novel Vibrio species, Vibrio antiquarius, isolated from a mesophilic bacterial community associated with hydrothermal vents located along the East Pacific Rise, near the southwest coast of Mexico. Genomic and phenotypic analysis revealed V. antiquarius is closely related to pathogenic Vibrio species, namely Vibrio alginolyticus, Vibrio parahaemolyticus, Vibrio harveyi, and Vibrio vulnificus, but sufficiently divergent to warrant a separate species status. The V. antiquarius genome encodes genes and operons with ecological functions relevant to the environment conditions of the deep sea and also harbors factors known to be involved in human disease caused by freshwater, coastal, and brackish water vibrios. The presence of virulence factors in this deep-sea Vibrio species suggests a far more fundamental role of these factors for their bacterial host. Comparative genomics revealed a variety of genomic events that may have provided an important driving force in V. antiquarius evolution, facilitating response to environmental conditions of the deep sea.W ith more than 110 recognized species, the genus Vibrio comprises a diverse group of heterotrophic bacteria, of which many are known pathogens, causing disease in animals and humans (1, 2). Vibrio cholerae is the most notorious because it is the causative agent of cholera. Vibrio vulnificus and Vibrio parahaemolyticus cause severe illness in humans and are associated with consumption of contaminated seafood (3, 4). Vibrio harveyi (5), Vibrio anguillarum (6, 7), and V. parahaemolyticus (8) continue to cause substantial economic losses to the aquaculture industry worldwide.Vibrios demonstrate a wide range of niche specialization: for example, free-living, attached to biotic and abiotic surfaces, and resident in both estuarine and marine habitats (9). The deep sea constitutes the largest habitat of the biosphere that supports microbial communities across three domains of life and represents an environment where physiochemical parameters-such as low temperature, high salinity, and high pressure-modulate community structure (10, 11). Several studies have shown the presence of physiologically, metabolically, and phylogenetically diverse mesophilic microbial communities in the deep sea, including Vibrio species (12-15). Barotolerant Vibrio spp. have been isolated from deep-sea sediment and from the gut microflora of invertebrates and fish collected from a variety of deepsea habitats, including hydrothermal vents (16,17). For example, strains of Vibrio, Aeromonas, and Pseudomonas spp. were isolated from mud-water samples collected at a depth of 4,940 m, 150 miles east of Cape Canaveral, Florida (18). Several culturedependent and -independent studies have confirmed the ubiquity of vibrios, and suggested Vibrio populations generally comprise approximately 1% (by molecular...
