the dnaj gene as a novel phylogenetic marker for identification of vibrio species.the utility of the dnaj gene for identifying vibrio species was investigated by analyzing dnaj sequences of 57 type strains and 22 clinical strains and comparing sequence homologies with those of the 16s rdna gene and other housekeeping genes (reca, rpoa, hsp60). among the 57 vibrio species, the mean sequence similarity of the dnaj gene (77.9%) was significantly less than that of the 16s rdna gene (97.2%), indicating a high discriminatory power of the dnaj gene. most vibrio species were, therefo ...200717207598

impact of environmental bacterial communities on fish health in marine recirculating aquaculture systems.marine cultured fish diseases caused by bacteria in recirculating aquaculture systems (rass) greatly threaten fish aquaculture. to date, the dynamics of bacterial populations in ras and their impacts to fish health remain largely unknown. in the present study, the bacterial communities in the water from two different marine rass were analyzed using pyrosequencing technique. fish disease syndromes and mortality had been reported from one ras (ras-d) while the fish in the other ras remained health ...201728619164
interspecific transmission and recovery of tcbs-induced disease between acanthaster planci and linckia guildingi.the susceptibility of the coral-feeding crown-of-thorns starfish acanthaster planci to disease may provide an avenue with which to effectively control population outbreaks that have caused severe and widespread coral loss in the indo-pacific. injecting thiosulfate-citrate-bile-sucrose (tcbs) agar into a. planci tissues induced a disease characterized by dermal lesions, loss of skin turgor, collapsed spines, and accumulation of mucus on spine tips. moreover, the symptoms (and presumably the agent ...201222968793
detection of acylated homoserine lactones produced by vibrio spp. and related species isolated from water and aquatic organisms.aims:  to assess the diversity in production of acylated homoserine lactones (ahls) among vibrio spp and related species. methods and results:  a total of 106 isolates, with representatives of 28 vibrio spp and related species, were investigated for the production of ahls. for this, a rapid method for the screening of ahls was developed based on the use of bacterial biosensors using a double-layer microplate assay. at least one bacterial biosensor was activated in 20 species, agrobacterium tumef ...201122098208
the function of integron-associated gene cassettes in vibrio species: the tip of the iceberg.the integron is a genetic element that incorporates mobile genes termed gene cassettes into a reserved genetic site via site-specific recombination. it is best known for its role in antibiotic resistance with one type of integron, the class 1 integron, a major player in the dissemination of antibiotic resistance genes across gram negative pathogens and commensals. however, integrons are ancient structures with over 100 classes (including class 1) present in bacteria from the broader environment. ...201324367362
deletion of integron-associated gene cassettes impact on the surface properties of vibrio rotiferianus dat722.the integron is a genetic recombination system that catalyses the acquisition of genes on mobilisable elements called gene cassettes. in vibrio species, multiple acquired gene cassettes form a cassette array that can comprise 1-3% of the bacterial genome. since 75% of these gene cassettes contain genes encoding proteins of uncharacterised function, how the integron has driven adaptation and evolution in vibrio species remains largely unknown. a feature of cassette arrays is the presence of large ...201323484028

unique and conserved genome regions in vibrio harveyi and related species in comparison with the shrimp pathogen vibrio harveyi caim 1792.vibrio harveyi caim 1792 is a marine bacterial strain that causes mortality in farmed shrimp in north-west mexico, and the identification of virulence genes in this strain is important for understanding its pathogenicity. the aim of this work was to compare the v. harveyi caim 1792 genome with related genome sequences to determine their phylogenic relationship and explore unique regions in silico that differentiate this strain from other v. harveyi strains. twenty-one newly sequenced genomes wer ...201526198743
taxonomic revision of harveyi clade bacteria (family vibrionaceae) based on analysis of whole genome sequences.use of inadequate methods for classification of bacteria in the so-called harveyi clade (family vibrionaceae, gammaproteobacteria) has led to incorrect assignment of strains and proliferation of synonymous species. in order to resolve taxonomic ambiguities within the harveyi clade and to test usefulness of whole genome sequence data for classification of vibrionaceae, draft genome sequences of 12 strains were determined and analysed. the sequencing included type strains of seven species: vibrio ...201323710045
