Organismes réglementés non de quarantaine : vers une plus large et meilleure application de ce concept international dans la région OEPP

Description du sujet. Les mesures définies sur les organismes réglementés non de quarantaine (ORNQ) visent à éviter un impact économique inacceptable suite à leur présence sur les végétaux destinés à la plantation et ce, bien que ces organismes nuisibles soient déjà présents dans la zone. Ainsi, contrairement aux organismes de quarantaine, le risque d'introduction des ORNQ n'est...

Microbial regulation of the soil carbon cycle: evidence from gene–enzyme relationships

A lack of empirical evidence for the microbial regulation of ecosystem processes, including carbon (C) degradation, hinders our ability to develop a framework to directly incorporate the genetic composition of microbial communities in the enzyme-driven Earth system models. Herein we evaluated the linkage between microbial functional genes and extracellular enzyme activity in soil...

Determining the Metabolic Footprints of Hydrocarbon Degradation Using Multivariate Analysis

The functional dynamics of microbial communities are largely responsible for the clean-up of hydrocarbons in the environment. However, knowledge of the distinguishing functional genes, known as the metabolic footprint, present in hydrocarbon-impacted sites is still scarcely understood. Here, we conducted several multivariate analyses to characterise the metabolic footprints...

Chemotaxis by natural populations of coral reef bacteria

Corals experience intimate associations with distinct populations of marine microorganisms, but the microbial behaviours underpinning these relationships are poorly understood. There is evidence that chemotaxis is pivotal to the infection process of corals by pathogenic bacteria, but this evidence is limited to experiments using cultured isolates under laboratory conditions. We...

Expanding the ‘central dogma’: the regulatory role of nonprotein coding genes and implications for the genetic liability to schizophrenia

It is now evident that nonprotein coding RNA (ncRNA) plays a critical role in regulating the timing and rate of protein translation. The potential importance of ncRNAs is suggested by the observation that the complexity of an organism is poorly correlated with its number of protein coding genes, yet highly correlated with its number of ncRNA genes, and that in the human genome...

Substrate Type Determines Metagenomic Profiles from Diverse Chemical Habitats

Environmental parameters drive phenotypic and genotypic frequency variations in microbial communities and thus control the extent and structure of microbial diversity. We tested the extent to which microbial community composition changes are controlled by shifting physiochemical properties within a hypersaline lagoon. We sequenced four sediment metagenomes from the Coorong, South...

Complete genome sequence of Thermosphaera aggregans type strain (M11TLT)

Thermosphaera aggregans Huber et al. 1998 is the type species of the genus Thermosphaera, which comprises at the time of writing only one species. This species represents archaea with a hyperthermophilic, heterotrophic, strictly anaerobic and fermentative phenotype. The type strain M11TLT was isolated from a water-sediment sample of a hot terrestrial spring (Obsidian Pool...

Complete genome sequence of Acidimicrobium ferrooxidans type strain (ICPT)

Acidimicrobium ferrooxidans (Clark and Norris 1996) is the sole and type species of the genus, which until recently was the only genus within the actinobacterial family Acidimicrobiaceae and in the order Acidomicrobiales. Rapid oxidation of iron pyrite during autotrophic growth in the absence of an enhanced CO2 concentration is characteristic for A. ferrooxidans. Here we describe...

Complete genome sequence of Pedobacter heparinus type strain (HIM 762-3T)

Pedobacter heparinus (Payza and Korn 1956) Steyn et al. 1998 comb. nov. is the type species of the rapidly growing genus Pedobacter within the family Sphingobacteriaceae of the phylum ‘Bacteroidetes’. P. heparinus is of interest, because it was the first isolated strain shown to grow with heparin as sole carbon and nitrogen source and because it produces several enzymes involved...

Complete genome sequence of Desulfomicrobium baculatum type strain (XT)

Desulfomicrobium baculatum is the type species of the genus Desulfomicrobium, which is the type genus of the family Desulfomicrobiaceae. It is of phylogenetic interest because of the isolated location of the family Desulfomicrobiaceae within the order Desulfovibrionales. D. baculatum strain XT is a Gram-negative, motile, sulfate-reducing bacterium isolated from water-saturated...

Complete genome sequence of Actinosynnema mirum type strain (101T)

Actinosynnema mirum Hasegawa et al. 1978 is the type species of the genus, and is of phylogenetic interest because of its central phylogenetic location in the Actinosynnemataceae, a rapidly growing family within the actinobacterial suborder Pseudonocardineae. A. mirum is characterized by its motile spores borne on synnemata and as a producer of nocardicin antibiotics. It is...

DIARRHEA-ASSOCIATED ADENOVIRUSES: RAPID PRESUMPTIVE DIAGNOSIS BY ELECTRON MICROSCOPY

There is a need for the rapid recognition of infection by the newly-described enteral or diarrhea-associated adenoviruses (adenoviruses that are of proposed neutralizing serotypes 40 and 41, or that have restriction endonuclease electrophoretic profiles of Wadell groups F or G). These viruses especially infect infants, and they tend to be fastidious in their growth in...
