“…Several cultivation-dependent and independent studies have showed that vibrios appear at particularly high densities in and/or on marine organisms, e.g., corals (331), fish (6,146,179,325), molluscs (345), seagrass, sponges, shrimp (133,(404)(405)(406) and zooplankton (163,194,365,408,409).…”

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

“…Other bacteria may enhance the growth of rotifers (Douillet, 2000) and of fish larvae (Skjermo & Vadstein, 1999). The principal genera identified in rotifer cultures have been Pseudomonas, Vibrio, Moraxella and Flavobacterium (Verdonck et al, 1994(Verdonck et al, , 1997. Vibrio was the dominant genus in rotifer cultures, constituting up to 56 % of the bacterial community, with Vibrio anguillarum, Vibrio alginolyticus, Vibrio diazotrophicus, Vibrio mediterranei and Vibrio tubiashii-like as representative species (Verdonck et al, 1997).…”

Five Gram-negative bacterial strains, oxidase-positive, motile by means of more than one polar flagella, facultative anaerobe, arginine dihydrolase-negative, lysine-and ornithine decarboxylasepositive, sensitive to the vibriostatic agent O/129, were isolated from a flow-through rotifer culture system in Gent, Belgium, and previously characterized by fluorescent amplified fragment length polymorphism. Comparison of the 16S rDNA sequence of strain LMG 21460 T indicated close relationships (,99 % similarity) to Vibrio campbellii, Vibrio harveyi, Vibrio alginolyticus and Vibrio parahaemolyticus. However, DNA hybridization experiments revealed similarity values below 70 % with its closest species V. campbellii and V. harveyi. Additionally, the analysed strains differ from related Vibrio species by the utilization of melibiose and production of acid from L-arabinose and amygdalin. Among the strains analysed, differences were observed in some phenotypic characters, particularly susceptibility to ampicillin, polymyxin B and amikacin, and urease activity. The major fatty acids identified were 16 : 0, 18 : 1w7c, 14 : 0, 12 : 0 3-OH and 18 : 0. Vibrio rotiferianus sp. nov. is proposed, with type strain LMG 21460 T (5CAIM 577 T ); it has a DNA G+C content of 44?5¡0?01 mol%.

“…Many studies were carried out on the mass culture of rotifers with different microalgal diets and at different temperatures and salinity conditions (Fielder et al, 2000;Hotos, 2002Hotos, , 2003Savas and Guclu, 2006;Kostopoulou and Vadstein, 2007;Jabeur et al, 2013;Abou-Shanab et al, 2016) in the rotifer tanks. Several researchers reported variations in rotifer density due to Vibrio infections which is a major constraint for high density production of rotifers (Skjermo and Vadstein, 1993;Verdonck et al, 1994Verdonck et al, , 1997Gomez-Gil et al, 2000;Rombaut et al, 2001;Prol-Garcia et al, 2010, Jayasree et al, 2016. Use of antibiotics in culture systems will lead to the development of antibiotic resistant strains of pathogenic bacteria and will also hinder the growth of cultured organisms.…”

An experimental study was carried out to evaluate the efficacy of three commercially available probiotics P1, P2 and P3 consisting of mainly Bacillus spp. and nitrifying bacteria against Vibrio loads in mass culture tanks of the rotifer Brachionus plicatilis. Triplicate tanks were maintained for each of the probiotic treatment as well as for control group. All the tanks were inoculated with 50 rotifers ml -1 and were fed with Nannochloropsis oculata at a density of 1 x 10 7 cells ml -1 . Every alternate day, all the experimental tanks were treated with probiotics at a concentration of 1 x 10 4 cfu ml -1 and the experiment was carried out for one week. The study showed a significant increase in rotifer density (p<0.05) in all the tanks treated with the probiotics and a maximum density of 400 nos. ml -1 was observed in the tanks treated with P3. After 5 th and 6 th day of culture, total elimination of Vibrios was also recorded in the tanks treated with P3 and P2 respectively. The study revealed that P3, with a combination of Bacillus, Thiobacillus, Acetobacter and Paracoccus supplemented with enzymes, was found to be most effective in the enhancement of rotifer density and also in the elimination of Vibrios in rotifer mass culture tanks.
