| vibrio kanaloae sp. nov., vibrio pomeroyi sp. nov. and vibrio chagasii sp. nov., from sea water and marine animals. | the taxonomic position of the fluorescent amplified fragment length polymorphism fingerprinting groups a46 (five isolates), a51 (six isolates), a52 (five isolates) and a53 (seven isolates) obtained in a previous study were further analysed through a polyphasic approach. the 23 isolates were phylogenetically related to vibrio splendidus, but dna-dna hybridization experiments proved that they belong to three novel species. chemotaxonomic and phenotypic analyses further disclosed several features t ... | 2003 | 12807197 |
| phylogenetic analysis of the incidence of lux gene horizontal transfer in vibrionaceae. | horizontal gene transfer (hgt) is thought to occur frequently in bacteria in nature and to play an important role in bacterial evolution, contributing to the formation of new species. to gain insight into the frequency of hgt in vibrionaceae and its possible impact on speciation, we assessed the incidence of interspecies transfer of the lux genes (luxcdabeg), which encode proteins involved in luminescence, a distinctive phenotype. three hundred three luminous strains, most of which were recently ... | 2008 | 18359809 |
| genomic diversity of vibrios associated with the brazilian coral mussismilia hispida and its sympatric zoanthids (palythoa caribaeorum, palythoa variabilis and zoanthus solanderi). | a taxonomic survey of the vibrios associated with the brazilian endemic coral mussismilia hispida and the sympatric zoanthids (i.e. palythoa caribaeorum, palythoa variabilis and zoanthus solanderi). | 2009 | 19291243 |
| denaturing gradient gel electrophoresis analyses of the vertical distribution and diversity of vibrio spp. populations in the cariaco basin. | the cariaco system is the second largest permanently anoxic marine water body in the world. its water column is characterized by a pronounced vertical layering of microbial communities. the goal of our study was to investigate the vertical distribution and diversity of vibrio spp. present in the cariaco basin waters using denaturing gradient gel electrophoresis (dgge) of pcr-amplified 16s rdna fragments. representatives of the vibrio genus were detected by nested and direct pcr in seawater at 10 ... | 2011 | 21507026 |
| phenotypic and genetic diversity of coexisting listonella anguillarum, vibrio harveyi and vibrio chagassi recovered from skin haemorrhages of diseased sand smelt, atherina boyeri, in the gulf of trieste (ne adriatic sea). | aims: identify and characterize coexisting vibrios associated with haemorrhagic skin lesion bearing sand smelt fishes (atherina boyeri) in north-eastern adriatic sea. methods and results: bacteria were isolated from external skin lesions of four samples and representative morphotypes grown on tcbs agar were isolated. in total 25 isolates, presumptively assigned to vibrio genus, were biochemically characterized and were grouped in 10 phenotypic profiles. phenotypes were heterogeneously distribu ... | 2011 | 22126646 |
| culturable microbiota of ranched southern bluefin tuna (thunnus maccoyii castelnau). | the australian tuna industry is based on the ranching of wild southern bluefin tuna (sbt, thunnus maccoyii). within this industry, only opportunistic pathogens have been reported infecting external wounds of fish. this study aimed to identify different culturable bacteria present in three cohorts of sbt and to determine normal bacteria and potential pathogens in isolates from harvest fish and moribund/dead fish. post-mortem changes in the microbiota were also studied. | 2013 | 23789748 |
| an mlsa approach for the taxonomic update of the splendidus clade, a lineage containing several fish and shellfish pathogenic vibrio spp. | a multilocus sequence analysis was undertaken in order to redefine the splendidus clade of the genus vibrio, a large group of species containing several pathogenic members that affect fish and shellfish, and are difficult to identify through both phenotypic and genotypic approaches. the study included analysis of partial sequences of reca, gyrb, mreb, rpod and pyrh genes, as well as the 16s rrna gene. seventeen type strain species were included that were complemented with other reference strains ... | 2016 | 27238556 |
