| updated phylogeny of the genus aeromonas. | recent phylogenetic studies of the genus aeromonas based on gyrb and rpod gene sequences have improved the phylogeny based on 16s rrna gene sequences first published in 1992, particularly in the ability to split closely related species. these studies did not include the recently described species aeromonas simiae and aeromonas molluscorum and only a single strain of aeromonas culicicola was available for analysis at that time. in the present work, these aeromonas species and newly isolated strai ... | 2006 | 17012583 |
| aeromonas rivuli sp. nov., isolated from the upstream region of a karst water rivulet. | two freshwater isolates (wb4.1-19(t) and wb4.4-101), sharing 99.9 % 16s rrna gene sequence similarity, were highly related to aeromonas sobria (99.7 % similarity; 6 bp differences). a phylogenetic tree derived from a multi-locus phylogenetic analysis (mlpa) of the concatenated sequences of five housekeeping genes (gyrb, rpod, reca, dnaj and gyra; 3684 bp) revealed that both strains clustered as an independent phylogenetic line next to members of aeromonas molluscorum and aeromonas bivalvium. the ... | 2011 | 20207806 |
| aeromonas sharmana sp. nov., isolated from a warm spring. | a gram-negative, facultatively anaerobic bacterial strain designated gptsa-6(t) was isolated from a water sample collected from a warm spring in assam, india. preliminary analysis of the 16s rrna gene sequence of this isolate revealed its affiliation to the family aeromonadaceae. detailed characterization using a polyphasic approach indicated that strain gptsa-6(t) is most closely related to aeromonas sobria but differs significantly from existing members of the genus aeromonas. analysis of the ... | 2006 | 16902029 |
| aeromonas molluscorum sp. nov., isolated from bivalve molluscs. | five aeromonas strains (848t(t), 93m, 431e, 849t and 869n), which were isolated from bivalve molluscs and were recognized previously by numerical taxonomy as members of an unknown aeromonas taxon, were subjected to a polyphasic taxonomic study. dna-dna hybridization experiments showed that dna of strain 848t(t) was <70 % similar (27-45 %) to that of the type/reference strains of the current aeromonas hybridization groups (hgs), but 93 % similar to that of strain 93m. the dna g+c content of the f ... | 2004 | 15545437 |
| a novel ttx-producing aeromonas isolated from the ovary of takifugu obscurus. | puffer fish (takifugu obscurus) from the yangtze river of china were screened for tetrodotoxin-producing bacteria. an aeromonas strain was isolated from the ovary of the puffer fish and was shown to produce tetrodotoxin; this strain was denoted ne-1. the identity of tetrodotoxin produced by strain ne-1 was confirmed by mouse bioassay, high performance liquid chromatography coupled with mass chromatography (lc-ms), and elisa. strain ne-1 was characterized morphologically, biochemically, and by 16 ... | 2010 | 20362605 |
| validation of a partial rpob gene sequence as a tool for phylogenetic identification of aeromonads isolated from environmental sources. | a collection of 50 aeromonads isolated from environmental sources were studied, together with all known aeromonas nomenspecies, by phenotypic, amplified 16s rdna restriction analysis (16s rdna rflp) and by partial sequence alignment of both 16s rdna and rpob genes. although most of the type strain showed a unique phenotypic pattern, a database constructed on type strain phenotype allowed the identification of only 24% of the isolates. analysis of 16s rdna rflp and the rpob sequence were almost c ... | 2010 | 20453908 |
| antimicrobial resistance and plasmid profile of bacterial strains isolated from the urbanized eltsovka-1 river (russia). | antimicrobial resistance and plasmid profile of gram-positive and gram-negative bacterial strains isolated from the urbanized eltsovka-1 river (russia) were investigated. sequencing of the 16s rrna of of g+ strains showed 99-100% identity to that of bacillus aerophilus, bacillus altitudinis, bacillus amyloliquefaciens, bacillus anthrancis, bacillus barbaricus, bacillus cereus, bacillus flexus, bacillus indriensis, bacillus stratosphericus, bacillus subtilis subsp. subtilis, bacillus thuringiensi ... | 2015 | 25803299 |
| suge: a gene involved in tributyltin (tbt) resistance of aeromonas molluscorum av27. | the mechanism of bacterial resistance to tributyltin (tbt) is still unclear. the results herein presented contribute to clarify that mechanism in the tbt-resistant bacterium aeromonas molluscorum av27. we have identified and cloned a new gene that is involved in tbt resistance in this strain. the gene is highly homologous (84%) to the aeromonas hydrophila-suge gene belonging to the small multidrug resistance gene family (smr), which includes genes involved in the transport of lipophilic drugs. i ... | 2013 | 23518517 |
| draft genome sequence of aeromonas molluscorum strain 848tt, isolated from bivalve molluscs. | we report here the draft genome sequence of aeromonas molluscorum 848t, the type strain of this aeromonas species, which was isolated from wedge shells (donax trunculus) obtained from a retail market in barcelona, spain, in 1997. | 2013 | 23788549 |
| transcriptomes analysis of aeromonas molluscorum av27 cells exposed to tributyltin (tbt): unravelling the effects from the molecular level to the organism. | aeromonas molluscorum av27 cells were exposed to 0, 5 and 50 μm of tbt and the respective transcriptomes were obtained by pyrosequencing. gene ontology revealed that exposure to 5 μm tbt results in a higher number of repressed genes in contrast with 50 μm of tbt, where the number of over-expressed genes is greater. at both tbt concentrations, higher variations in gene expression were found in the functional categories associated with enzymatic activities, transport/binding and oxidation-reductio ... | 2015 | 26171931 |
| a microcosm approach to evaluate the degradation of tributyltin (tbt) by aeromonas molluscorum av27 in estuarine sediments. | tributyltin (tbt) is a biocide extremely toxic to a wide range of organisms, which has been used for decades in antifouling paints. despite its global ban in 2008, tbt is still a problem of great concern due to the high levels trapped in sediments. aeromonas molluscorum av27 is a tbt degrading bacterium that was isolated from an estuarine system. we investigated the ability and the role of this bacterium on tbt degradation in this estuarine system, using a microcosm approach in order to mimic en ... | 2014 | 24858283 |
| aeromonas molluscorum av27 is a potential tributyltin (tbt) bioremediator: phenotypic and genotypic characterization indicates its safe application. | aeromonas molluscorum av27 is an estuarine bacterium highly resistant to tributyltin (tbt). also, the strain is able to degrade tbt into the less toxic compounds dibutyltin and monobutyltin. therefore, this bacterium has potential to be employed in bioremediation processes. in this context, defining its biological safety is crucial. with that purpose a number of intrinsic characteristics, usually present/associated with virulent strains, were investigated. few virulence factors were detected in ... | 2013 | 23828177 |
