Barley pathogens in Iceland: Identification, virulence and genetic structure of major barley pathogens in Iceland
… analyzed leaves, including two widespread barley pathogens, Rhynchosporium secalis and Pyrenophora teres f. teres, the causal agents of scald and net blotch, respectively. The genetic structure of the Icelandic R. secalis population was studied using thirteen microsatellite markers and results …

Transcriptional stress response in foodborne pathogens
… of molecular methods targeting foodborne pathogens provides genetic profiling and targeted intervention methods. Whole-genome sequencing (WGS) provides information on the genomic uniqueness of specific pathogens and is being implemented in epidemiological investigations. Transcriptomic …

DESIGNING BIOMIMETIC NANOPARTICLES TO TACKLE INTRACELLULAR PATHOGENS
… in modern medicine, certain bacterial pathogens such as Mycobacterium abscessus (Mab) continue to evade therapeutic clearance by creating intracellular reservoirs within host macrophages. Conventional drug delivery systems often fall short due to their lack of precision, limited …

Inactivation of foodborne pathogens by fruit wines
… possess bactericidal properties on a number of pathogens in vitro, suggesting possible health benefits that may be derived from microbiological safety. This study investigated the bactericidal effects in wines made from fruits other than grape. The foodborne pathogens Escherichia coli O157:H7, …

Approaches towards disease resistance to filamentous pathogens
… the co-evolutionary arms race between plants and pathogens, plants have developed a multifaceted armory consisting of diverse defence responses, such as the production of antimicrobial compounds and the activation of immunity via specific receptors. This work examines the use of the phytoalexin …

Aetiological links between oral pathogens and dementia.
… to demonstrate the presence of red complex pathogens when analysed using molecular methodologies. However, immunofluorescence labelling of a virulence factor (LPS) was positive for P. gingivalis in 4 out of 10 AD cases. Immunoblotting demonstrated bands corresponding to P. ginigivalis LPS in …

Investigating dynein-based transport of intracellular pathogens
… cellular cargoes, it can also be hijacked by pathogens that rely on intracellular transport for parts of their replicative cycle. This phenomenon is well exemplified by the obligate intracellular bacterium Orientia tsutsugamushi, which exploits dynein and microtubules to reach its subcellular …

Methylobacterium spp.: Emerging Opportunistic Premise Plumbing Pathogens
Opportunistic premise plumbing pathogens (OPPPs) are responsible for many infections linked to drinking water. The annual cost of disease caused by these waterborne pathogens is $850 million. Key characteristics of these opportunistic waterborne pathogens include: disinfectant- resistant, biofilm …

Studies of Three Human Intestinal Opportunistic Pathogens
Opportunistic bacterial pathogens are present in the intestines of all mammals. These bacteria are symbionts to a certain extent, but under certain conditions these organisms can be deadly. Intestinal opportunistic pathogens encompass many genera and include organisms such as those in the …

New molecular mechanisms of Arabidopsis thaliana resistance to necrotrophic pathogens = New molecular mechanisms of Arabidopsis thaliana resistance to necrotrophic pathogens
… controlling plant defence to this type of pathogens, we have explored the relevance of additional, uncharacterized molecular components of Arabidopsis thaliana. Thus, we have demonstrated that A. thaliana secondary cell wall is not just a structural defensive barrier, but is also an …

Interacting populations : hosts and pathogens, prey and predators
The interactions between populations can be positive, neutral or negative. Predation and parasitism are both relationships where one species benefits from the interaction at the expense of the other. Predators kill their prey instantly and use it only for food, whereas parasites use their hosts …

Epidemiological Models For Mutating Pathogens With Temporary Immunity
Significant progress has been made in understanding different scenarios for disease transmissions and behavior of epidemics in recent years. A considerable amount of work has been done in modeling the dynamics of diseases by systems of ordinary differential equations. But there are very few …

Ticks And Tick-Borne Pathogens In North Dakota
… 2010 a statewide survey of ticks and tick-borne pathogens was conducted in North Dakota. Ticks were collected from the four eco-regions in the state by flagging for questing adults and by collecting feeding immature ticks from trapped small mammals. I collected 1762 individual ticks representing …

Characterisation of bacteriophage dynamics associated with foodborne pathogens
… phage-bacteria interactions involving foodborne pathogens. Using models that incorporate phage interactions with both pathogens and commensal bacteria this thesis explores the way in which phages can impact bacterial colonisation and colonisation resistance. To establish the conceptual and …

Polyprenyl-dependent glycan assembly pathways in microbial pathogens
Polyisoprenyl-dependent glycan assembly pathways form the basis for the biosynthesis of many complex glycoconjugates. This thesis addresses key aspects of undecaprenyl-phosphate related processes; undecaprenol is the linear polyisoprenol that is utilized by virtually all known bacterial species. In …

Mucin and mucin glycans alter behaviorof mucosal pathogens
… as a protective barrier. Mucus physically blocks pathogens and other microorganisms from reaching host cells; however, mucus additionally decreases the virulence of certain opportunistic pathogens to prevent infections. A greater understanding of mucus’ spectrum of activity could lead to future …
