The organism had chemotaxonomic and morphological properties that were consistent with its assignment to the genus Dietzia and it formed a distinct phyletic line within the Dietzia 16S rRNA gene tree. It shared a 16S rRNA gene sequence similarity of 98.3 % with its nearest neighbour, the type strain of Dietzia cinnamea, and could be distinguished from the type strains of all Dietzia species using a combination of phenotypic properties. It is apparent from genotypic and phenotypic data that the organism represents a novel species in the genus Dietzia. The name proposed for this taxon is Dietzia papillomatosis; the type strain is N 1280T (5DSM 44961T5NCIMB 14145T).

  • Integrative Biology Defines Novel Biomarkers of Resistance To
    www.nature.com/scientificreports OPEN Integrative biology defnes novel biomarkers of resistance to strongylid infection in horses Guillaume Sallé1*, Cécile Canlet2, Jacques Cortet1, Christine Koch1, Joshua Malsa1, Fabrice Reigner3, Mickaël Riou4, Noémie Perrot4, Alexandra Blanchard5 & Núria Mach6 The widespread failure of anthelmintic drugs against nematodes of veterinary interest requires novel control strategies. Selective treatment of the most susceptible individuals could reduce drug selection pressure but requires appropriate biomarkers of the intrinsic susceptibility potential. To date, this has been missing in livestock species. Here, we selected Welsh ponies with divergent intrinsic susceptibility (measured by their egg excretion levels) to cyathostomin infection and found that their divergence was sustained across a 10-year time window. Using this unique set of individuals, we monitored variations in their blood cell populations, plasma metabolites and faecal microbiota over a grazing season to isolate core diferences between their respective responses under worm-free or natural infection conditions. Our analyses identifed the concomitant rise in plasma phenylalanine level and faecal Prevotella abundance and the reduction in circulating monocyte counts as biomarkers of the need for drug treatment (egg excretion above 200 eggs/g). This biological signal was replicated in other independent populations. We also unravelled an immunometabolic network encompassing plasma beta-hydroxybutyrate level, short-chain fatty acid producing bacteria and circulating neutrophils that forms the discriminant baseline between susceptible and resistant individuals. Altogether our observations open new perspectives on the susceptibility of equids to strongylid infection and leave scope for both new biomarkers of infection and nutritional intervention. Infection by gastro-intestinal nematodes is a major burden for human development worldwide as they both afect human health1 and impede livestock production2.

Abstract: Sea cucumbers are a class of marine invertebrates and a source of food and drug. Numerous microorganisms are associated with sea cucumbers. Seventy-eight genera of bacteria belonging to 47 families in four phyla, and 29 genera of fungi belonging to 24 families in the phylum Ascomycota have been cultured from sea cucumbers. Sea-cucumber-associated microorganisms produce diverse secondary metabolites with various biological activities, including cytotoxic, antimicrobial, enzyme- inhibiting, and antiangiogenic activities. In this review, we present the current list of the 145 natural products from microorganisms associated with sea cucumbers, which include primarily polyketides, as well as alkaloids and terpenoids. These results indicate the potential of the microorganisms associated with sea cucumbers as sources of bioactive natural products.

Hamid Department of Clinical Microbiology and Parasitology, College of Medicine, King Khalid University, P. O. Box 641, Abha, Kingdom of Saudi Arabia. Accepted 5 July, 2013 Many infective agents are implicated as causal agents of mastitis. Miscellaneous causes of mastitis in bovine due to actinomycetes such as nocardiae have been described but neither Rhodococcus nor Dietzia species have been reported. The aim of this study was to report the isolation and characterization of rhodococcus-like actinomycetes as causal agents of mastitis in cattle. Milk samples (n = 100) collected from cattle suffering from mastitis in Sudan were subjected to microscopic examination using modified Ziehl Neelsen stains and cultured on Trpytic Soya agar medium. Out of the 100 milk samples collected from cattle suffering from mastitis in Sudan, five (5%) revealed rhodococcus-like growth which showed gram-positive coccobacilli. Two of the five samples showed partially acid-fast coccobacilli when milk samples were directly stained with modified Ziehl Neelsen method. The isolates were tentatively identified as members of the genus Rhodococcus on the basis of morphological, biochemical and mycolic acids pattern. Comparative analysis of the 16S rDNA gene sequence confirmed that the strains fall within the phylogenetic branch which accommodates members of the genus Dietzia, but well separated from the validly described Dietzia spp.

The isolation of actinobacteria from unique environments has resulted in the discovery of new antibiotic compounds that can be used by the pharmaceutical industry. In this study, the fynbos biome was identified as one of these unique habitats due to its rich plant diversity that hosts over 8500 different plant species, including many medicinal plants. In this study two medicinal plants from the fynbos biome were identified as unique environments for the discovery of bioactive actinobacteria, Aloe ferox (Cape aloe) and Sutherlandia frutescens (cancer bush). Actinobacteria from the genera Streptomyces, Micromonaspora, Amycolatopsis and Alloactinosynnema were isolated from these two medicinal plants and tested for antibiotic activity. Actinobacterial isolates from soil (248; 188), roots (0; 7), seeds (0; 10) and leaves (0; 6), from A. ferox and S. frutescens, respectively, were tested for activity against a range of Gram-negative and Gram-positive human pathogenic bacteria.

The preferred substrate was the very long-chain alkane n-eicosane at an optimal temperature of 37 °C and an optimal pH of 8 under aerobic conditions. The growth and substrate uptake kinetics were monitored during the n-alkane fermentation process, and Dietzia sp. E1 cells were found to possess three distinct levels of cell-surface hydrophobicity. Gas chromatographic/mass spectrometric analysis revealed that intracellular substrate mineralization occurred through the conversion of n-alkane to the corresponding n-alkanal. The monoterminal oxidation pathway was pre- sumably initiated by AlkB and CYP153 terminal alkane hydroxylases, both of their partial coding sequences were successfully detected in the genome of strain E1, a novel member of the Dietzia genus.

The genus Dietzia was recently distinguished from other actinomycetes such as Rhodococcus. While these organisms are known to be distributed widely in the environment, over the past decade several novel species have been described and isolated from human clinical specimens. Here we describe the identification of Dietzia natronolimnaea/D. cercidiphylli by PCR amplification and sequencing of the 16S rRNA encoding gene from cardiac tissue in a patient with culture-negative device-associated endocarditis. 1.

He also had weight loss that he could not Blood culture-negative endocarditis is a term used to describe quantify and a poor appetite.
