Pathogenic Vibrio Isolated from Cultured Eels—II
TL;DR: It is impossible to differentiate this organism provisionally classified as Vibrio anguillicida BRUUN and HEIBERG in the previous report from Vibria fischeri in terms of the above-mentioned two characters.

Abstract: The preceding papers(MUROGA et al., 1976 a, b)dealt with the biochemical characteristics, taxonomical status, physiological characters and pathogenicity of Vibrio sp. isolated from a new eel vibriosis.In this paper the effect of NaCl concentrations of cultrue media on the NaCl tolerance and on the flagellation of the vibrio were examined, and these two characters of the organism were reconsidered by way of comparison with those of Vibrio fischeri.The experimental results together with considerations are given as under.1) NaCl tolerance : The lower limit falled to 0.1% after consecutive culture in the media containing 0.3% NaCl. The upper limit, in contrast with this, raised to 6% in case of the media with 4% NaCl. The range of 0.1 to 6% is applicable to the NaCl tolerance range of this organism in view of these results.2) flagellation: Cells having more than one flagellum at one pole occurred in cultures grown on nutrient agar plate, of which the higher the NaCl concentration (0.5-4.5%), the higher the percent occurrence (0.22-20%). Cells, however, had one polar flagellum in cultures grown in nutrient broth except in the broth with extremely high concentration (4%) of NaCl. Accordingly it may be safely said that the flagellation of this organism is monotrichous.In conclusion it is impossible to differentiate this organism provisionally classified as Vibrio anguillicida BRUUN and HEIBERG in the previous report (MUROGA et al., 1976a) from Vibrio fischeri in terms of the above-mentioned two characters.

Heterogeneity among isolates of Vibrio vulnificus recovered from eels (Anguilla anguilla) in Denmark.
TL;DR: It is demonstrated that Vibrio vulnificus isolates recovered from diseased eels in Denmark are heterogeneous as shown by O serovars, capsule types, ribotyping, phage typing, and plasmid profiling.

TL;DR: A new updated classification of the species is proposed based on phylogenetic lineages rather than on Bts, as well as the inclusion of all Bt2 strains in a pathovar with the particular ability to cause fish vibriosis, for which the name “piscis” is suggested.
Detection of Vibrio vulnificus biotypes 1 and 2 in eels and oysters by PCR amplification.
TL;DR: This is the first report on the detection of cells of V. vulnificus naturally present in shellfish and represents a potentially powerful method for monitoring this important human and eel pathogen.

Phenotypic and genotypic characterization of a new fish-virulent Vibrio vulnificus serovar that lacks potential to infect humans.
TL;DR: A new BT2 serovar [serovar A (SerA)], which emerged in the European fish-farming industry in 2000, was characterized by means of phenotypic, serological and genetic methodologies and confirmed that SerA constitutes a homogeneous O-serogroup within the species that shares plasmidic information with SerE.

Staining, shape and arrangement of bacterial flagella.
TL;DR: The flagella staining technique to be described is a modification and perfection of that originally published by the author in 1930 and appears to be a characteristic of sufficient stability and distinctiveness to justify the classification of flagellated bacteria into several groups.

Effects of some physical factors on flagellation and swarming of Vibrio alginolyticus
TL;DR: Vibrio alginolyticus strains recently isolated from Dutch coastal seawater changed flagellar organization when cultivated in the presence of certain chemical agents.

Flagellar antigens of various species of the genus Vibrio and related genera.
TL;DR: The antigenicity of purified flagellin prepared from the single polar flageLLum of Vibrio parahaemolyticus was found to be common to that of all strains tested, i.e., V. alginolyticUS, V. cholerae,V.
Effect of temperature, salts, pH, and other factors on the development of peritrichous flagella in Vibrio alginolyticus.
TL;DR: The development of peritrichous flagella and swarming of Vibrio alginolyticus depend on a complex relationship between temperature, salt concentrations and pH.

TL;DR: In this article, the utility of the phenotypic and genotypic approaches to the determination of relatedness is discussed, and patterns of the relatedness inferred from DNA criteria were found to correlate closely with those inferred from morphological, physiological, and serological analysis of the same organisms.
