  2. 16. Host responses to malaria and bacterial co-­infections

    Author : Maria Nelson; Johan Normark; Sven Bergström; Anna Fahlgren; Olle Stendahl; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Plasmodium; Malaria; Borrelia; S. pneumoniae; Co-infection; Immunology; Metabolomics;

    Abstract : The two main causes of child mortality and morbidity in Africa are malaria and invasive bacterial diseases. In addition, co-infections in sub-Saharan Africa are the rule rather than the exception. However, not much is known about the host-pathogen interaction during a concomitant infection or how it affects the outcome of disease. READ MORE

  4. 17. Bacterial interaction with the fibrinolytic system and extracellular matrix

    Author : Thomas Herrman Eberhard; Karolinska Institutet; Karolinska Institutet; []
    Keywords : plasminogen; extracellular matrix; basement membrane; virulence factors; fibronectin; vitronectin; collagen; Haemophilus influenzae Neisseria meningitidis Streptococcus pneumoniae;

    Abstract : Bacterial infection of host organisms is a state of complex interaction between the parasite and the host. Two critical steps in the infectious process are: Adhesion to the epithelial surfaces and penetration of tissue barriers to gain entrance to tissues and into the circulation. These two steps have been the subjects of this thesis. READ MORE

  5. 18. Decoding the language of transmission among vector-pathogen-host

    Author : Melika Hajkazemian; S. Noushin Emami; Richard Hopkins; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Vector-borne disease; Malaria; Anopheles; Plasmodium falciparum; Zika; Aedes; Vector control strategy; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Vector-borne diseases account for over 17 percent of all infectious diseases and lead to more than 700,000 mortalities annually. Importantly, there is a complex interaction between infectious organisms and their host. READ MORE

  6. 19. Parasite antigens and cellular interactions associated with the membrane of Plasmidium falciparum infected erythrocytes

    Author : Wipaporn Ruangjirachuporn; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The asexual erythrocytic stages of malaria parasites are the cause of the pathological manifestations of the disease, Plasmodium falciparum being the species notorious for causing serious complications. This thesis describes studies on parasite-host cell interactions at two different stages of the P. READ MORE

  7. 20. Virulence mechanisms of two gram negative bacteria : studies on Escherichia coli hemolysin HlyA and on the interaction of Brucella abortus with non-phagocytic cells

    Author : Caterina Guzman-Verri; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Virulence factors may be classified in two general groups: those that cause damage to the host and those that promote bacterial colonization and invasion. In this study, the tissue damaging Escherichia coli hemolysin HlyA and the mechanism of internalization of the intracellular parasite Brucella abortus were investigated. READ MORE
