Human-pathogenic Vibrio bacteria are common inhabitants of oyster tissues, but our understanding factors driving the wide range concentrations found in individual oysters is extremely limited. We examined influence sex and parasitism light their profound effects on tissues against a backdrop eastern oysters, Crassostrea virginica, from two diploid triploid aquacultured lines. This allowed us to...

Vibrio mimicus, the species most similar to V. cholerae, is a microbe present in the natural environmental and sometimes causes diarrhea and internal infections in humans. It shows similar phenotypes to V. cholerae but differs in some biochemical characteristics. The molecular mechanisms underlying the differences in biochemical metabolism between V. mimicus and V. cholerae are currently unclea...

AIMS To determine the relationship between yellow band disease (YBD)-associated pathogenic bacteria found in both Caribbean and Indo-Pacific reefs, and the virulence of these pathogens. YBD is one of the most significant coral diseases of the tropics. MATERIALS AND RESULTS The consortium of four Vibrio species was isolated from YBD tissue on Indo-Pacific corals: Vibrio rotiferianus, Vibrio ha...

Five strains were isolated from moribund scallop (Pecten maximus) larvae over 5 years (1990-1995) during outbreaks of disease in a hatchery (Argenton, Brittany, France). Their pathogenic activity on scallop larvae was previously demonstrated by experimental exposure. The phenotypic and genotypic features of the strains were identical. The G + C content of the strains was in the range 39-41 mol%...

The aims of this study were to count and identify sucrose positive and negative vibrios isolated from cultivated Crassostrea rhizophorae oysters during their growing cycle. Every month for 12 months, 10 to 18 oysters were collected for study. Collections occurred at the Center for Studies of Coastal Aquaculture (CSCA), which is associated with the Institute of Marine Science, Labomar, located i...

Vibrio splendidus is a dominant culturable Vibrio in seawater, and strains related to this species are also associated with mortality in a variety of marine animals. The determinants encoding the pathogenic properties of these strains are still poorly understood; however, the recent sequencing of the genome of V. splendidus LGP32, an oyster pathogen, provides an opportunity to decipher the basi...

This Research Topic brings together 24 articles that highlight the most recent research findings concerning the biology of the genus Vibrio and covers pathogenicity and host interaction, genome plasticity and evolution, and the dynamics of factors influencing the ecology of vibrios. Vibrio comprises one of the most diverse marine bacterial genera (Gomez-Gil et al., 2014), and its diversity is e...

Fish larvae in aquaculture have high mortality rates due to pathogenic bacteria, especially the Vibrio species, and ineffective prophylactic strategies. Vaccination is not feasible in larvae and antibiotics have reduced efficacy against multidrug resistant bacteria. A novel approach to controlling Vibrio infections in aquaculture is needed. The potential of phage therapy to combat vibriosis in ...

Coastal region of Chah Bahar port, Sea of Oman, was screened for the presence of bioluminescence bacteria for the first time. Water samples were taken from surface and subsurface layers and immediately spread on nutrient seawater complete (SWC) agar. Luminous colonies were observed after an overnight incubation at 25°C. Among twenty luminous isolates, four of them were selected for preliminary ...
