“…Six phylotypes in this study cluster with Vibrio genera known as pathogens. Vibrio alginolyticus (four phylotypes) causes soft tissue infections and is listed as a human pathogen, whereas Vibrio splendidus (two phylotypes) is known to be a fish pathogen (Farmer III and Hickman-Brenner 2006). Some of these species have been associated with mortality in a wide range of marine animals, such as molluscs, fish, shrimps and octopus (Beaz-Hidalgo et al 2009).…”

Copepods can be associated with different kinds and different numbers of bacteria. This was already shown in the past with culture-dependent microbial methods or microscopy and more recently by using molecular tools. In our present study, we investigated the bacterial community of four frequently occurring copepod species, Acartia sp., Temora longicornis, Centropages sp. and Calanus helgolandicus from Helgoland Roads (North Sea) over a period of 2 years using DGGE (denaturing gradient gel electrophoresis) and subsequent sequencing of 16S-rDNA fragments. To complement the PCR-DGGE analyses, clone libraries of copepod samples from June 2007 to 208 were generated. Based on the DGGE banding patterns of the two years survey, we found no significant differences between the communities of distinct copepod species, nor did we find any seasonality. Overall, we identified 67 phylotypes ([97 % similarity) falling into the bacterial phyla of Actinobacteria, Bacteroidetes, Firmicutes and Proteobacteria. The most abundant phylotypes were affiliated to the Alphaproteobacteria. In comparison with PCR-DGGE and clone libraries, phylotypes of the Gammaproteobacteria dominated the clone libraries, whereas Alphaproteobacteria were most abundant in the PCR-DGGE analyses.

“…The culture was plated on thiosulfate citrate bile salt sucrose (TCBS) agar (HIMEDIA, India). Further it was identified by morphological and biochemical conformations (Farmer and Hickman-Brenner 1992) as well as based on the characteristics described in Bergey's Manual of systematic bacteriology (Holt et al 1994). The isolates were oxidase positive, sensitive to vibriostatic agents, grown in nutrient broth (HIMEDIA, India) with 3% and 6% NaCl and TCBS agar.…”

Immunostimulating influence of herbal biomedicines on nonspecific immunity in Grouper Epinephelus tauvina juvenile against Vibrio harveyi infection

Herbals such as Cynodon dactylon, Piper longum, Phyllanthus niruri, Tridax procumbens, and Zingiber officinalis were extracted with acetone, benzene, butanol, and petroleum ether and screened against the pathogen Vibrio harveyi isolated from the infected Grouper Epinephalus tauvina. Among the different solvent extractions screening to V. harveyi, petroleum ether extracts were suppressed significantly (P \ 0.05). Equal proportions of the all-plant extracts were mixed with the artificial feeds at concentrations of 100, 200, 400, and 800 mg kg -1 of diet and fed to grouper juveniles of 20 ± 2 g average weight for a period of 60 days. Every 20 days, fish juveniles were challenged with V. harveyi and the immune response was studied. The herbal diets significantly (P \ 0.05) increased the survival, growth, and immune responses compared to the control group. The herbal diets were significantly improved (P \ 0.01) in immune parameters such as phagocytic activity and albumin-globulin (A-G) ratio. Among the different concentrations of the herbals in the diet, the 400 mg kg -1 diet was the most effective in the experiment.

“…Classical phenotypic tests were performed as described previously (Baumann et al, 1984;Farmer & Hickman-Brenner, 1992;Leifson, 1963). The ability of the cultures to utilize various carbon compounds as the sole carbon source was investigated by testing 0.5 % carbon compound in a minimal base medium containing 2.0 % (w/v) NaCl, 1.0 % (w/v) K 2 HPO 4 , 0.45 % (w/v) KH 2 PO 4 , 0.14 % (w/v) CaCl 2 , 0.15 % (w/v) MgCl 2 , 0.075 % (w/v) KCl, 0.1 % (w/v) (NH 4 ) 2 SO 4 and 1.5 % (w/v) agar.…”

Vibrio porteresiae sp. nov., a diazotrophic bacterium isolated from a mangrove-associated wild rice (Porteresia coarctata Tateoka) Two facultatively anaerobic, nitrogen-fixing bacteria (strains MSSRF30 T and MSSRF31) were isolated from a mangrove-associated wild rice (Porteresia coarctata Tateoka). These strains were determined to be nitrogen-fixers using the acetylene reduction assay and by PCR detection of a nifH gene amplicon. Phylogenetic analyses based on 16S rRNA gene sequences indicated that the novel strains were most closely related to Vibrio fluvialis LMG 7894 T (96.8 % gene sequence similarity), Vibrio furnissii LMG 7910 T (96.8 % sequence similarity) and Vibrio tubiashii CIP 102760 T (96.7 % sequence similarity). Further multilocus sequence analysis using recA, pyrH, rpoA and nifH genes also showed low levels of sequence similarities (83-93 %) with all species of the genus Vibrio with validly published names. A multigene phylogenetic tree using concatenated sequences of the four genes (16S rRNA, rpoA, recA and pyrH) showed that strains MSSRF30 T and MSSRF31 occupied a distinct phylogenetic position, forming a long branching that was not clustered with any other recognized Vibrio species. The fatty acid profile also suggested that the novel strains belonged to the genus Vibrio. The results of physiological and biochemical tests, genomic fingerprinting and DNA-DNA hybridization analyses clearly differentiated both novel strains from their closest phylogenetic neighbours, Vibrio cholerae IID6019, Vibrio mimicus LMG 7896 T , V. fluvialis LMG 7894 T and V. furnissii LMG 7910 T . Several phenotypic traits enabled the differentiation of strain MSSRF30 T from other species of the genus Vibrio. The DNA G+C content of strain MSSRF30 T was 44.4±3.1 mol%. Based on genotypic, phenotypic, chemotaxonomic, phylogenetic and DNA-DNA hybridization analyses, the name Vibrio porteresiae sp. nov. (type strain MSSRF30 T 5LMG 24061 T 5DSM 19223 T ) is proposed for this novel taxon.The genus Vibrio encompasses a genetically diverse group of heterotrophic marine bacteria that are commonly found in aquatic habitats and in association with marine organisms (Thompson et al., 2004a). Members of the genus Vibrio may account for nearly 10 % of the culturable marine bacteria (Thompson et al., 2004b). They include several species that are pathogenic for humans and marine animals and some that are facultative symbiotic (Thompson et al., 2004a). To date, relatively few studies have demonstrated that vibrios are capable of N 2 -fixation; this characteristic has so far been confirmed for Vibrio diazotrophicus (Guerinot et al., 1982), Vibrio natriegens, Vibrio pelagius and Vibrio cincinnatiensis (Urdaci et al., 1988), Vibrio anguillarum and Vibrio campbellii (Holguin et al., 1992).During a study of diazotrophic bacteria from mangroveassociated wild rice, numerous isolates that could fix atmospheric nitrogen were isolated. Based on the preliminary characterization, these isolates were tentatively identified as members of the genera Swamina...
