“…V. anguillarum, V. salmonicida, and V. vulnificus are among the main bacterial pathogens of several fish species (14), and V. harveyi is a major pathogen of shrimp, e.g., Litopenaeus vannamei and Penaeus monodon (15,225,227). Mortality caused by vibrios in reared fish and shellfish is very common during early larval stages and can occur suddenly, leading sometimes to death of the entire population (42,96,157,184,185,187,217,230,283,287,295). Pathogenicity of V. harveyi is associated with the presence of a bacteriophage (15,291).…”

Vibrios are ubiquitous and abundant in the aquatic environment. A high abundance of vibrios is also detected in tissues and/or organs of various marine algae and animals, e.g., abalones, bivalves, corals, fish, shrimp, sponges, squid, and zooplankton. Vibrios harbour a wealth of diverse genomes as revealed by different genomic techniques including amplified fragment length polymorphism, multilocus sequence typing, repetetive extragenic palindrome PCR, ribotyping, and whole-genome sequencing. The 74 species of this group are distributed among four different families, i.e., Enterovibrionaceae, Photobacteriaceae, Salinivibrionaceae, and Vibrionaceae. Two new genera, i.e., Enterovibrio norvegicus and Grimontia hollisae, and 20 novel species, i.e., Enterovibrio coralii, Photobacterium eurosenbergii, V. brasiliensis, V. chagasii, V. coralliillyticus, V. crassostreae, V. fortis, V. gallicus, V. hepatarius, V. hispanicus, V. kanaloaei, V. neonatus, V. neptunius, V. pomeroyi, V. pacinii, V. rotiferianus, V. superstes, V. tasmaniensis, V. ezurae, and V. xuii, have been described in the last few years. Comparative genome analyses have already revealed a variety of genomic events, including mutations, chromosomal rearrangements, loss of genes by decay or deletion, and gene acquisitions through duplication or horizontal transfer (e.g., in the acquisition of bacteriophages, pathogenicity islands, and super-integrons), that are probably important driving forces in the evolution and speciation of vibrios. Whole-genome sequencing and comparative genomics through the application of, e.g., microarrays will facilitate the investigation of the gene repertoire at the species level. Based on such new genomic information, the taxonomy and the species concept for vibrios will be reviewed in the next years

“…Based mainly on the relatively low DNA homology values found and on its differential phenotypical features with V. harveyi, L. anguillarum and Vibrio parahaemolyticus, it was proposed as a new species (Iwamoto et al, 1995), although the disease symptoms in fish and phenotypical characteristics of V. trachuri and V. harveyi were quite similar (Austin & Austin, 1999 ;Iwamoto et al, 1995).…”

NOTEThe taxonomic position of Vibrio trachuri was examined through a polyphasic approach using 16S rDNA sequencing, fluorescent amplified fragment length polymorphisms (FAFLP), DNA-DNA hybridization experiments, GMC content of DNA and phenotypical tests. Phylogenetic analysis showed that Vibrio harveyi is the closest neighbour of V. trachuri, sharing about 988 % similarity in the 16S rDNA gene. Moreover, numerical analysis of the FAFLP patterns revealed that both species have highly related genomes, sharing 55 % pattern similarity. DNA-DNA hybridization experiments and GMC content measurements reinforced these results, since V. trachuri and V. harveyi had at least 74 % DNA similarity and 445-452 mol % GMC. Phenotypical features of both species were also very similar, except that V. trachuri utilized itaconic acid, whereas V. harveyi did not. Therefore, it is proposed that the species V. trachuri should be reclassified as V. harveyi.

“…Zoea could be genetically differentiated from V. harveyi and V. campbellii by lower DNA-DNA homologies than 70%, however, this group could not be separated clearly from V. harveyi especially milkfish isolates by phenotypic traits (Tables 2 and 3). Iwamoto et al (1995) proposed the name V.trachuri to a pathogen of Japanese horse mackerel (Trachurus K. Ishimaru and K. Muroga Table 2. Biochemical and physiological characteristics of Vibrio harveyi and Vibrio sp.…”

A taxonomical re-examination of two pathogenic bacteria belonging to the genus Vibrio, one from an eye disease of milkfish (Chanos chanos) in the Philippines and the other from vibriosis of larval swimming crab (Portunus trituberculatus) in Japan, was made by examining their phenotypic features and measuring DNA-DNA relatedness.As a result, the bacterium from milkfish was identified as V. harveyi based on the high DNA homology value of above 84% between the two milkfish isolates and the type strain of V. harveyi and coincidence in phenotypic characteristics.Strain 85Z-1, the representative strain of the causative bacterium (Vibrio sp. Zoea) of vibriosis in swimming crab, showed higher DNA relatedness than 75% to other 3 strains of Vibrio sp. Zoea, about 50% relatedness to strains of V. harveyi, and lower relatedness than 46% to the other species examined.These results indicate that Vibrio sp. Zoea is a new genomic species most closely to V. harveyi.However, it is difficult to distinguish phenotypically Vibrio sp. Zoea from V. harveyi isolated from milkfish, thus species name for Vibrio sp. Zoea could not be proposed.
