“…genus Desulfovibrio; however, the strain was distantly related to the known relatives. Of the closest relatives, D. dechloracetivorans is not yet validly published as based on Rules 27(3) and 30 of the Bacteriological Code (De Vos and Trüper, 2000;Euzéby and Tindall, 2004). D. dechloracetivorans was isolated from bay sediment and reported to have a specifi c ability to conduct reductive dechlorination of 2-chlorophenol (Sun et al, 2000).…”

“…Aeromonas taxonomy has undergone numerous changes (Joseph and Carnahan 2000) with an increasing number of species being identified in recent years (Euzéby and Tindall 2004;Harf-Monteil et al 2004;Miñana-Galbis et al 2004). Five species of Aeromonas, Aeromonas hydrophila, Aeromonas caviae, Aeromonas veronii biovar sobria, Aeromonas jandei and Aeromonas schubertti, have been associated with human disease (Janda and Abbott 1998), with Aer.…”

Prevalence of environmental Aeromonas in South East Queensland, Australia: a study of their interactions with human monolayer Caco-2 cells

Aims: To investigate the prevalence of Aeromonas in a major waterway in South East Queensland, Australia, and their interactions with a gut epithelial model using Caco-2 cells. Methods and Results: A total of 81 Aeromonas isolates, collected from a major waterway in South East Queensland, Australia, were typed using a metabolic fingerprinting method, and tested for their adhesion to HEp-2 and Caco-2 cells and for cytotoxin production on Vero cells and Caco-2 cells. Aeromonas hydrophila had the highest (43%) and Aeromonas veronii biovar sobria had the lowest (25%) prevalence. Four patterns of adhesion were observed on both HEp-2 and Caco-2 cell lines. Representative isolates having different phenopathotypes (nine strains) together with two clinical isolates were tested for their translocation ability and for the presence of virulence genes associated with pathogenic Escherichia coli. The rate and degree of translocation across Caco-2 monolayers varied among strains and was more pronounced with LogA pattern. Translocation was associated with the adherence of strains to Caco-2 cells microvilli, followed by internalization into Caco-2 cells. Two Aer. veronii biovar sobria strains were positive for the presence of heat-labile toxin genes, with one strain also positive for Shiga-like toxin gene. Conclusions: Pathogenic strains of Aeromonas carrying one or more virulence characteristics are highly prevalent in the waterways studied and are capable of translocating across a human enterocyte cell model. Significance and Impact of the Study: This study indicates that Aeromonas strains carrying one or more virulence properties are prevalent in local waterways and are capable of translocating in a human enterocyte cell culture model. However, their importance in human gastrointestinal disease has yet to be verified under competitive conditions of the gut.

Sphingobium yanoikuyae B1 utilizes both polycyclic aromatic hydrocarbons (biphenyl, naphthalene, and phenanthrene) and monocyclic aromatic hydrocarbons (toluene, m- and p-xylene) as its sole source of carbon and energy for growth. The majority of the genes for these intertwined monocyclic and polycyclic aromatic pathways are grouped together on a 39 kb fragment of chromosomal DNA. However, this gene cluster is missing several genes encoding essential enzymatic steps in the aromatic degradation pathway, most notably the genes encoding the oxygenase component of the initial polycyclic aromatic hydrocarbon (PAH) dioxygenase. Transposon mutagenesis of strain B1 yielded a mutant blocked in the initial oxidation of PAHs. The transposon insertion point was sequenced and a partial gene sequence encoding an oxygenase component of a putative PAH dioxygenase identified. A cosmid clone from a genomic library of S. yanoikuyae B1 was identified which contains the complete putative PAH oxygenase gene sequence. Separate clones expressing the genes encoding the electron transport components (ferredoxin and reductase) and the PAH dioxygenase were constructed. Incubation of cells expressing the dioxygenase enzyme system with biphenyl or naphthalene resulted in production of the corresponding cis-dihydrodiol confirming PAH dioxygenase activity. This demonstrates that a single multicomponent dioxygenase enzyme is involved in the initial oxidation of both biphenyl and naphthalene in S. yanoikuyae B1.
