introduction: white spot syndrome virus (wssv) is one of the most deadly infectious pathogens of the shrimp culture industry. neither effective vaccines nor efficient treatments are currently available for this disease. vibrio species are well known dominant bacterial pathogens in the shrimp ponds. as facultative pathogenic bacteria, it is possible that vibrio spp. along with wssv to co-infect ...

OmpU porins are increasingly recognized as key determinants of pathogenic host Vibrio interactions. Although mechanisms remain incompletely understood, various species, including the human pathogen Vibrio cholera, require OmpU for host colonization and virulence. We have shown previously that OmpU is essential for virulence in the oyster pathogen Vibrio splendidus LGP32. Here, we showed that V....

The cultivated Pacific oyster Crassostrea gigas has suffered for decades large scale summer mortality phenomenon resulting from the interaction between the environment parameters, the oyster physiological and/or genetic status and the presence of pathogenic microorganisms including Vibrio species. To obtain a general picture of the molecular mechanisms implicated in C. gigas immune responsivene...

Bacteria of the genus Vibrio are indigenous for the marine environment and temporarily in abundances in the ocean, causing infections to humans and commercially important species of crustaceans, bivalves and fish. These bacteria can therefore cause severe complications for human health and large economic losses to aquaculture. A polymerase chain reaction (PCR) technique was used to detect prese...

Vibrio fluvialis is an important food-borne pathogen that causes diarrheal illness and sometimes extraintestinal infections in humans. In this study, we sequenced the genome of a clinical V. fluvialis strain and determined its phylogenetic relationships with other Vibrio species by comparative genomic analysis. We found that the closest relationship was between V. fluvialis and V. furnissii, fo...

20 Vibrio fluvialis is an important foodborne pathogen that causes diarrheal illness and 21 sometimes extraintestinal infections in humans. In this study, we sequenced the genome 22 of a clinical V. fluvialis strain and determined its phylogenetic relations to other Vibrio 23 species by comparative genomic analysis. We found that the closest relationship was 24 between V. fluvialis and V. furni...

Background：Vibrio splendidusVs is an important aquaculture pathogen that can infect a broad host of marine organisms. In our previous study, an antagonistic bacterium Vibrio sp. V33 that possessed inhibitory effects on the growth and virulence of a pathogenic isolate V.splendidusVs was identified. O...

Capsular polysaccharide (CPS) is essential for the dispersal of biofilms formed by the pathogenic bacterium Vibrio vulnificus CPS production is induced by the quorum-sensing (QS) master regulator SmcR when biofilms mature. However, V. vulnificus biofilms formed under heat shock conditions did not exhibit the dispersion stage. Transcripts of the CPS gene cluster were at basal levels in the heat-...

Here we investigate the diversity of pathogenic Vibrio species in marine environments close to Suva, Fiji. We use four distinct yet complementary analyses - biochemical testing, phylogenetic analyses, metagenomic analyses and molecular typing - to provide some preliminary insights into the diversity of vibrios in this region. Taken together our analyses confirmed the presence of nine Vibrio spe...

We resolved the relationships between 2 pandemic clones of Vibrio cholerae. Using 26 housekeeping genes, we showed that the US Gulf clone, the Australian clone, and 3 El Tor strains isolated before the seventh pandemic were related to the seventh pandemic clone. The sixth pandemic clone was well separated from them.
