  2. 1. 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

  5. 3. 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; []

    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.
