Abstract:
BACKGROUND:Clostridium difficile is an important cause of intestinal infections in some animal species and animals might be a reservoir for community associated human infections. Here we describe a collection of animal associated C. difficile strains from 12 countries based on inclusion criteria of one strain (PCR ribotype) per animal species per laboratory.RESULTS:Altogether 112 isolates were collected and distributed into 38 PCR ribotypes with agarose based approach and 50 PCR ribotypes with sequencer based approach.

The hypothesis that midge sex pheromones could be chemically more diverse in structure than previously thought was tested in the context of four midge species of importance to UK horticulture: pear leaf midge, Dasineura pyri; pear midge, Contarinia pyrivora; blackcurrant midge, D. tetensi; and blackberry midge, D. plicatrix. The major component of the pheromone of D. pyri was identified as (2R, 13R, 8Z)-2, 13-diacetoxy-8-heptadecene. Four isomers were separated by HPLC and in field tests the first eluting isomer only was attractive to male midges. Analysis of volatile collections from female C

Abstract:
The dromedary camel (Camelus dromedarius) commonly referred to as ‘ship of the desert’ has played an important part in the development and expansion of trading networks across inhospitable habitats over 3000 years, linking Arabian, Asian, African and European civilisations. Caravan roads, which are part of the major trading networks, have facilitated livestock exchange across large geographic distances. Dromedary camels are known to have been extensively used as pack animals along these caravan roads. Archaeological records point towards the southern Arabian Peninsula as the origin of the dome

Although viruses are ubiquitous, infecting all biological entities including viruses themselves, we know relatively little of viral diversity beyond those implicated in diseases affecting humans and domestic plants and animals. Recent advances in metagenomic sequencing technologies, particularly bulk RNA shotgun sequencing ('meta-transcriptomics'), have enabled a dramatic increase in our understanding of virus diversity and evolution. However, although likely central to disease emergence, the total viral diversity (i.e. virome) of many vertebrates and their eukaryotic parasites remain uncharac

The genetic diversity in modern species is strongly affected by contemporary gene flow between populations, which in turn is governed by individual dispersal capacities and barriers in the landscape.

Abstract:
Traditional dogma is that men have a higher metabolism compared to women. Because of an increased obesity rate in women, the purpose of this study was to test the hypothesis that compared to males, females will gain more body weight per gram of food consumed. Methods: To test our hypothesis male and female mice were fed either a high or low-fat diet for 20-weeks, while monitoring food intake and body weight. At the end of the 20 week feeding plan, a final weight on the mice was taken, as well as a measurement from the nose to rump of the mouse in order to calculate a BMI. Results: Male mice

Abstract:
The Pacific Northwest is known for its once-abundant wild salmonid populations that have been in decline for more than 50 years due to habitat destruction and commercial overexploitation. To compensate, federal and state agencies annually release hundreds of thousands of hatchery-reared fish into the wild. However, accumulating data indicate that hatchery fish have lower fitness in natural environments, and that hatchery rearing negatively influences return rates of anadromous salmonids. Recently, mounting evidence revealed that the richness and diversity of intestinal microbial species influe

Abstract:
The genome of a Korean isolate of Hepatopancreatic parvovirus (HPV) was partially cloned, sequenced and characterized. Random PCR amplification of viral DNA was combined with conventional cloning methods to generate three clones named HPV8 (2,136 bp insert), HPV3 (1,560 bp insert), and CP1139 (413 bp insert). DNA sequencing demonstrated overlapping regions between HPV8 and HPV3 and between HPV3 and CPII39. The combined sequence of these three clones encompass approximately 3,350 bp of the total 5,000 bp estimated for the HPV genome. A large open reading frame (1,692 bp) was found within clones
