“…A very important diagnostic phenotypic feature for the identification of Vibrio species has always been the presence of flagella and thus motility (3). Nonmotile Vibrio species, e.g., the V. halioticoli group, have described (344,346,347), suggesting that the presence of flagella is not an essential diagnostic feature. Likewise, oxidase-negative V. metschnikovii and V. gazogenes strains have been documented, as have Vibrio strains that fail to grow on TCBS (4, 5).…”

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

Seven non-motile, facultatively anaerobic, alginolytic marine bacteria were isolated from the cultured clams Ruditapes philippinarum and Ruditapes decussatus. Phylogenetic analysis based on 16S rRNA gene sequences showed that these marine bacteria were closely related to the recently described species Vibrio comitans, Vibrio rarus and Vibrio inusitatus (¢99.0 % sequence similarity). Phylogenetic analysis based on the housekeeping genes rpoA, recA and atpA grouped the isolates together and allocated them to the Vibrio halioticoli species group. Amplified fragment length polymorphism DNA fingerprinting also grouped them together and enabled them to be differentiated from recognized species of the V. halioticoli clade. DNA-DNA hybridizations showed that the isolates belonged to a novel species; phenotypic features such as the ability to grow at 4 6C and in the presence of 6 % NaCl also enabled them to be separated from other species. The DNA G+C content of RD 15.11 T is 44.4 mol%. The genotypic and phenotypic data showed that the isolates represent a novel species in the V. halioticoli clade. The name Vibrio breoganii sp. nov. is proposed, with RD 15.11 T (5CECT 7222 T 5LMG 23858 T ) as the type strain.During the last decade, the number of Vibrio species has increased rapidly. At present, there are more than 70 recognized Vibrio species. It is known that these fermentative bacteria constitute a high proportion of the heterotrophic bacteria associated with marine bivalves, especially oysters, mussels and clams (Kueh & Chan, 1985;Pujalte et al., 1993;Gó mez-Leó n et al., 2005). Several Vibrio species can be pathogenic and are associated with disease outbreaks (Prado et al., 2005); therefore, accurate identification of these micro-organisms is important. The multilocus sequence analysis technique has greatly improved the taxonomy of strains belonging to the Vibrionaceae and many existing species have been assigned to specific groups. These groups are usually named after a representative species in the group, e.g. the splendidus, diazotrophicus, scophthalmi, fischeri, harveyi or halioticoli clades, among others (Thompson et al., 2007;Sawabe et al., 2007b). Species of the Vibrio halioticoli clade are found in association with ecological niches in the gut of Haliotis species and are alginolytic, non-motile, unflagellated and fermentative marine bacteria. The V. halioticoli clade consists at present of eight species: V. halioticoli, V. superstes, V. neonatus, V. ezurae, V. gallicus, V. comitans, V. inusitatus and V. rarus. V. halioticoli was first described by Sawabe et al. (1998). V. comitans, V. inusitatus and V. rarus were described more recently (Sawabe et al., 2007a). Strains of the V. halioticoli clade have been found all over the world, including Japan (Sawabe et al., 1995(Sawabe et al., , 1998(Sawabe et al., , 2002(Sawabe et al., , 2004a(Sawabe et al., , 2007a, Australia (Hayashi et al., 2003), South Africa (Sawabe et al., 2003) and France (Sawabe et al., 2004b).
