Inferring the Evolutionary History of Vibrios by Means of Multilocus Sequence Analysis
ABSTRACT We performed the first broad study aiming at the reconstruction of the evolutionary history of vibrios by means of multilocus sequence analysis of nine genes. Overall, 14 distinct cladesExpand
Vibrios Commonly Possess Two Chromosomes
The prevalence of the two-chromosome configuration was investigated in 34 species of vibrios and closely related species and suggests that the structure of the small chromosome is more flexible than that of the large chromosome during the evolution of vibRIos. Expand
Phylogenetic relationships of marine bacteria, mainly members of the family Vibrionaceae, determined on the basis of 16S rRNA sequences.
The phylogenetic relationships of 50 reference strains, mostly marine bacteria which require Na+ for growth, were determined on the basis of 600 16S rRNA nucleotides by using reverse transcriptase sequencing, and the family Vibrionaceae was separated into at least seven groups (genera and families).

Taxonomy of four marine bacterial strains that produce tetrodotoxin.
Four strains of tetrodotoxin-producing bacteria isolated from a red alga and from pufferfish were characterized. Two of these strains are members of the genus Listonella MacDonell and Colwell. TheExpand
Pseudomonas plecoglossicida sp. nov., the causative agent of bacterial haemorrhagic ascites of ayu, Plecoglossus altivelis.
A new Pseudomonas species was isolated from cultured ayu (Plecoglossus altivelis) with bacterial haemorrhagic ascites that reduced nitrate to nitrite and was distinguished phenotypically from PseUDomonas putida biovar A by utilization of D-malate, L-(+)-tartrate, m-Tartrate and nicotinate. Expand
Microbial diversity in marine sediments from Sagami Bay and Tokyo Bay, Japan, as determined by 16S rRNA gene analysis.
Although the depths of SB and TK were very different, the community diversity inferred from ARDRA and the taxonomic position of the dominant clones were similar, indicating that the microbial diversity of SA was higher than at the other two stations. Expand
Identification of Flexibacter maritimus, Flavobacterium branchiophilum and Cytophaga columnaris by PCR targeted 16S ribosomal DNA
The specific primers for Flexibacter maritimus, Flavobacterium branchiophilum, and Cytophaga columnaris were constructed and the specificity in amplifying the 16S rDNA of each species was confirmed by using selected strains of related bacteria and principal fish pathogenic bacteria. Expand
Identification of Cytophaga psychrophila by PCR Targeted 16S Ribosomal RNA
The present PCR technique is expected to be a powerful tool for the diagnosis of cold-water disease and distinguished C. psychrophila from other principal fish pathogens. Expand
A proposal to transfer Vibrio marinus (Russell 1891) to a new genus Moritella gen. nov. as Moritella marina comb. nov.
There is now strong evidence that V. marinus should be reclassified as Moritella marina gen. nov, and the 11 isolates fell into a single cluster that was clearly distinct from other genera. Expand
Vibrio azureus sp. nov., a luminous marine bacterium isolated from seawater.
It can be concluded that two luminous marine bacterial strains isolated from seawater at Kuroshio Region and Sagami Bay in Japan belong to the same genospecies and represent a novel species of the genus Vibrio, for which the name VIBrio azureus sp. Expand
