  2. 1. Differentiation and Pathogenicity within the Saprolegniaceae : Studies on Physiology and Gene Expression Patterns in Saprolegnia parasitica and Aphanomyces astaci

    Author : Gunnar Andersson; Michael J. Bidochka; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Zoophysiology; Zoofysiologi; Animal physiology; Zoofysiologi; fysiologisk mykologi; Physiological Mycology;

    Abstract : Saprolegnia parasitica and Aphanomyces astaci are parasitic water moulds belonging to the Oomycetes. Despite their importance as parasites they are very little studied at the molecular level and the work described in this thesis was aimed at increasing the molecular knowledge of these organisms by cloning and characterising genes of potential importance for reproduction and pathogenicity.

  4. 2. Immune defense reactions in freshwater crayfish : Cellular components

    Author : Charlotta Ekblom; Irene Söderhäll; Kallaya Sritunyalucksana-Dangtip; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; crustaceans; hemocytes; immunity; crayfish; proteomics; transcriptomics; Biology with specialization in Comparative Physiology; Biologi med inriktning mot jämförande fysiologi;

    Abstract : The freshwater signal crayfish, Pacifastacus leniusculus, is a well-established model for studying the immune system of invertebrates. Many important discoveries have been made in this species, among others related to the clotting reaction, hematopoiesis, the prophenoloxidase activating system, the functions of crustacean immune cells, and pathogen recognition.

  5. 3. Parasite on Crayfish : Characterisation of Their Pathogenesis, Host Interactions and Diversity

    Author : Eakaphun Bangyeekhun; Anders Tunlid; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Zoophysiology; Crayfish; Parasite; Oomycete; Prophenoloxidase; Peroxinectin; Aphanomyces astaci; Psorospermium haecheli; White spot syndrome virus; Zoofysiologi; Animal physiology; Zoofysiologi; biologisk beroendeforskning; Biological Research on Drug Dependence;

    Abstract : The crayfish plague refractory crayfish, Pacifastacus leniusculus, which can harbour the fungal parasite within melanotic sheath, are found to constitutively express the gene encoding for prophenoloxidase (proPO) after mimicking parasite attack. In contrast, the susceptible crayfish, Astacus astacus, responds to the parasite by increased levels of proPO transcript, particularly in the semigranular haemocytes. READ MORE

  6. 4. Virulence mechanisms of pathogenic Yersinia : aspects of type III secretion and twin arginine translocation

    Author : Moa Lavander; Åke Forsberg; George Salmond; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Yersinia pestis; Yersinia pseudotuberculosis; bacterial pathogenesis; type III secretion; twin arginine translocation; virulence mechanisms; YscU; YscP; YscF; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : The pathogenic bacteria Yersinia pestis and Y. pseudotuberculosis are related to the degree where the former is considered a subspecies of the latter, and still they cause disease of little resemblance in humans. Y. pestis is the causative agent of lethal bubonic and pneumonic plague, while Y. READ MORE

  7. 5. Photodynamic Therapy utilizing Interstitial Light Delivery Combined with Spectroscopic Methods

    Author : Marcelo Soto Thompson; Atomfysik; []
