  2. 1. Parasite on Crayfish : Characterisation of Their Pathogenesis, Host Interactions and Diversity

    Author : Eakaphun Bangyeekhun; Anders Tunlid; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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

  4. 2. Studies of Giardia-host interactions: role of cysteine-rich surface proteins

    Author : Dimitra Peirasmaki; Staffan Svärd; Steven Singer; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Giardia; intestinal parasite; parasite infection; host-parasite interaction; virulence factors; HCMPs; cysteine-rich proteins; secretome; proteome;

    Abstract : Giardia intestinalis is a eukaryotic parasite that colonizes the small intestine of humans and animals causing the diarrheal disease known as giardiasis. This parasite is not invasive and does not internalize into host cells but it rather attaches to the brush border surface of the small intestine disrupting the epithelial barrier. READ MORE

  5. 3. Immunologic aspects of the pathogenesis of human onchocerciasis

    Author : Magdi Mahmoud Ali; Klavs Berzins; Norbert Brattig; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Immunology; Immunologi;

    Abstract : Onchocerciasis, or river blindness, is a parasitic disease that affects more than 20 million people globally. The induction of pathology is directly related to the presence and destruction of the microfilarial stages (mf) of this filarial nematode. READ MORE

  6. 4. Host-parasite interactions in the dissemination of Toxoplasma gondii

    Author : Sachie Kanatani; Antonio Barragan; Per Uhlén; Isabelle Tardieux; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Apicomplexa; dendritic cells; microglia; cell migration; 14-3-3 proteins; GABAergic signaling; voltage-dependent calcium channel; host-parasite interaction; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Toxoplasma gondii is an obligate intracellular parasite that infects virtually all warm-blooded organisms. Systemic dissemination of T. gondii in the organism can cause life-threatening infection that manifests as Toxoplasma encephalitis in immune-compromised patients. READ MORE

  7. 5. Pathogenesis and Cell Biology of the Salmon Parasite Spironucleus salmonicida

    Author : Ásgeir Ástvaldsson; Staffan Svärd; Jon Jerlström-Hultqvist; Scott Dawson; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Diplomonads; Spironucleus; Giardia; genome; annexin; oxygen stress; APEX; pathology;

    Abstract : Spironucleus species are classified as diplomonad organisms, diverse eukaryotic flagellates found in oxygen-deprived environments. Members of Spironucleus are parasitic and can infect a variety of hosts, such as mice and birds, while the majority are found to infect fish. READ MORE
