| vibrio crassostreae sp. nov., isolated from the haemolymph of oysters (crassostrea gigas). | polyphasic analysis of five new vibrio isolates originating from the haemolymph of diseased cultured oysters is described. the new isolates were closely related to vibrio splendidus, having 98 % 16s rrna gene sequence similarity. gyrb phylogenetic analysis, fluorescent amplified-fragment length polymorphism (faflp) fingerprinting and dna-dna hybridization experiments clearly showed that the new isolates form a tight genomic group that is different from the currently known vibrio species. it is p ... | 2004 | 15545447 |
| population dynamics of vibrio and pseudomonas species isolated from farmed tasmanian atlantic salmon (salmo salar l.): a seasonal study. | vibrio and pseudomonas species have been shown to be part of the normal microbiota of atlantic salmon (salmo salar l.), with some strains causing disease in fish. the factors affecting their prevalence and persistence in the salmon gut, however, have not been well studied. in this study, we collected 340 vibrio and 150 pseudomonas isolates from the hindgut of farmed tasmanian atlantic salmon, fed with two commercially available diets. samples were collected every 6-8 weeks between july 2011 and ... | 2014 | 25027277 |
| vibrio crassostreae, a benign oyster colonizer turned into a pathogen after plasmid acquisition. | vibrios are frequently associated with oyster mortality; however whether they are the primary causative agent or secondary opportunistic colonizers is not well understood. here we combine analysis of natural infection dynamics, population genomics and molecular genetics to ask (i) to what extent oysters are passively colonized by vibrio population present in the surrounding water, (ii) how populations turn over during pathogenicity events and (iii) what genetic factors are responsible for pathog ... | 2017 | 27922600 |
| colonization of polystyrene microparticles by vibrio crassostreae: light and electron microscopic investigation. | microplastics collected at sea harbor a high diversity of microorganisms, including some vibrio genus members, raising questions about the role of microplastics as a novel ecological niche for potentially pathogenic microorganisms. in the present study, we investigated the adhesion dynamics of vibrio crassostreae on polystyrene microparticles (micro-ps) using electronic and fluorescence microscopy techniques. micro-ps were incubated with bacteria in different media (zobell culture medium and art ... | 2016 | 27640445 |
| new vibrio species associated to molluscan microbiota: a review. | the genus vibrio consists of more than 100 species grouped in 14 clades that are widely distributed in aquatic environments such as estuarine, coastal waters, and sediments. a large number of species of this genus are associated with marine organisms like fish, molluscs and crustaceans, in commensal or pathogenic relations. in the last decade, more than 50 new species have been described in the genus vibrio, due to the introduction of new molecular techniques in bacterial taxonomy, such as multi ... | 2014 | 24427157 |
| vibrio cortegadensis sp. nov., isolated from clams. | a group of four strains isolated from clams (venerupis decussata and venerupis philippinarum) in galicia (nw spain) were subjected to a polyphasic characterization, based on the phenotypic characteristics, the analysis of chemotaxonomic features, the sequencing of the 16s rrna and five housekeeping (atpa, pyrh, reca, rpoa and rpod) genes, as well as dna-dna hybridization (ddh). the analysis of the phenotypic and chemotaxonomic characteristics and the results of a phylogenetic study, based on the ... | 2014 | 24271473 |
| characterization of vibrios diversity in the mucus of the polychaete myxicola infundibulum (annellida, polichaeta). | vibrios are among the most abundant culturable microbes in aquatic environments. they can be either free-living in the water column or associated with several marine organisms as mutualists, saprophytes, or parasites. in the present study we analysed vibrios abundance and diversity in the mucus of the polychaete myxicola infundibulum, complementing culture-based with molecular methods. vibrios reached 4.6 × 10(3) cfu ml(-1) thus representing a conspicuous component of the heterotrophic culturabl ... | 2014 | 24194098 |
| environmental vibrios represent a source of antagonistic compounds that inhibit pathogenic vibrio cholerae and vibrio parahaemolyticus strains. | with the overuse of antibiotics, many pathogens including vibrio cholerae and vibrio parahaemolyticus have evolved multidrug resistance making treatment more difficult. while understanding the mechanisms that underlie pathogenesis is crucial, knowledge of bacterial interactions of v. cholerae and v. parahaemolyticus could provide insight to their susceptibility outside of the human host. based on previous work showing competition among environmental strains, we predict that marine-derived bacter ... | 2017 | 28857444 |
