vibrios dominate as culturable nitrogen-fixing bacteria of the brazilian coral mussismilia hispida.taxonomic characterization was performed on the putative n(2)-fixing microbiota associated with the coral species mussismilia hispida, and with its sympatric species palythoa caribaeorum, p. variabilis, and zoanthus solanderi, off the coast of são sebastião (são paulo state, brazil). the 95 isolates belonged to the gammaproteobacteria according to the 16s rdna gene sequences. in order to identify the isolates unambiguously, pyrh gene sequencing was carried out. the majority of the isolates (n = ...200818678453
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).200919291243
archaea, bacteria, and algal plastids associated with the reef-building corals siderastrea stellata and mussismilia hispida from búzios, south atlantic ocean, brazil.reef-building corals may be seen as holobiont organisms, presenting diverse associated microbial communities. best known is the symbiotic relationship with zooxanthellae, but archaea, bacteria, fungi, viruses, and algal plastids are also abundant. until now, there is little information concerning microbial communities associated with brazilian corals. the present study aims to describe the diversity of archaea, bacteria, and eukaryotic algal plastid communities associated with two sympatric spec ...201020013262
marinobacterium coralli sp. nov., isolated from mucus of coral (mussismilia hispida).a gram-negative, aerobic bacterium, designated r-40509(t), was isolated from mucus of the reef builder coral (mussismilia hispida) located in the são sebastião channel, são paulo, brazil. the strain was oxidase-positive and catalase-negative, and required na(+) for growth. its phylogenetic position was in the genus marinobacterium and the closest related species were marinobacterium sediminicola, marinobacterium maritimum and marinobacterium stanieri; the isolate exhibited 16s rrna gene sequence ...201120154332
vibrio communis sp. nov., isolated from the marine animals mussismilia hispida, phyllogorgia dilatata, palythoa caribaeorum, palythoa variabilis and litopenaeus vannamei.eight vibrio isolates originating from the marine corals mussismilia hispida and phyllogorgia dilatata and the zoanthids palythoa caribaeorum and palythoa variabilis in brazil and the pacific white shrimp (litopenaeus vannamei) in ecuador were studied by means of a polyphasic approach. the novel isolates formed a tight monophyletic group in the genus vibrio and were closely related to species of the vibrio harveyi group, to which they showed more than 99 % 16s rrna gene sequence similarity. anal ...201120305064
bacterial community associated with healthy and diseased reef coral mussismilia hispida from eastern order to characterize the bacterial community diversity associated to mucus of the coral mussismilia hispida, four 16s rdna libraries were constructed and 400 clones from each library were analyzed from two healthy colonies, one diseased colony and the surrounding water. nine bacterial phyla were identified in healthy m. hispida, with a dominance of proteobacteria, actinobacteria, acidobacteria, lentisphaerae, and nitrospira. the most commonly found species were related to the genera azospiri ...201020352207
marinomonas brasilensis sp. nov., isolated from the coral mussismilia hispida, and reclassification of marinomonas basaltis as a later heterotypic synonym of marinomonas communis.a gram-negative, aerobic bacterium, designated strain r-40503(t), was isolated from mucus of the reef-builder coral mussismilia hispida, located in the são sebastião channel, são paulo, brazil. phylogenetic analyses revealed that strain r-40503(t) belongs to the genus marinomonas. the 16s rrna gene sequence similarity of r-40503(t) was above 97 % with the type strains of marinomonas vaga, m. basaltis, m. communis and m. pontica, and below 97 % with type strains of the other marinomonas species. ...201120562247
diversity and pathogenic potential of vibrios isolated from abrolhos bank corals.we performed the first taxonomic characterization of vibrios and other culturable microbiota from apparently healthy and diseased brazilian-endemic corals at the abrolhos reef bank. the diseases affecting corals were tissue necrosis in phyllogorgia dillatata, white plague and bleaching in mussismilia braziliensis and bleaching in mussismilia hispida. bacterial isolates were obtained from mucus of 22 coral specimens originated from the abrolhos bank (i.e. itacolomis reef, recife de fora reef and ...201023766002
comparative genomics of paracoccus sp. sm22m-07 isolated from coral mucus: insights into bacteria-host of the main goals of coral microbiology is to understand the ways in which coral-bacteria associations are established and maintained. this work describes the sequencing of the genome of paracoccus sp. sm22m-07 isolated from the mucus of the endemic brazilian coral species mussismilia hispida. comparative analysis was used to identify unique genomic features of sm22m-07 that might be involved in its adaptation to the marine ecosystem and the nutrient-rich environment provided by coral mucus, ...201627796486
draft genome sequence of kocuria sp. sm24m-10 isolated from coral, we describe the genomic features of the actinobacteria kocuria sp. sm24m-10 isolated from mucus of the brazilian endemic coral mussismilia hispida. the sequences are available under accession number ldnx01000000 ( the genomic analysis revealed interesting information about the adaptation of bacteria to the marine environment (such as genes involved in osmotic and oxidative stress) and to the nutrient-rich environment provided by the coral m ...201626981384
the role of competition in the phase shift to dominance of the zoanthid palythoa cf. variabilis on coral reefs.phase shift phenomena are becoming increasingly common. however, they are also opportunities to better understand how communities are structured. in southwest atlantic coral reefs, a shift to the zoanthid palythoa cf. variabilis dominance has been described. to test if competition drove this process, we carried out a manipulative experiment with three coral species. to estimate the natural frequency of encounters we assess the relationship between the proportion of encounters and this zoanthids ...201626849036
bacterial communities and species-specific associations with the mucus of brazilian coral species.we investigated the existence of species-specific associations between brazilian coral species and bacteria. pyrosequencing of the v3 region of the 16s rdna was used to analyze the taxonomic composition of bacterial communities associated with the mucus of four coral species (madracis decactis, mussismilia hispida, palythoa caribaeorum, and tubastraea coccinea) in two seasons (winter and summer), which were compared with the surrounding water and sediment. the microbial communities found in samp ...201323567936
