  1. 6. Caenorhabditis elegans as a model to elucidate host-pathogen interactions for human bacterial pathogens

    Författare :Xiao Hui Sem; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The soil nematode Caenorhabditis elegans is a popular host utilized to model bacterial virulence and microbial pathogenesis in vivo. This thesis explores the use of C. elegans for the study of host-pathogen interactions for two Gram-negative bacteria, Burkholderia thailandensis and Salmonella enterica. LÄS MER

  3. 7. Studies on the molecular mechanisms of resistance to fluoroquinolones and carbapenems in selected bacterial species

    Författare :Nagwa Mustafa El Amin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The emergence of mutant bacteria with multi-resistant phenotype, no longer responsive to any of the available therapeutic agents is a growing concern. We have investigated the resistance mechanisms to two classes of antibacterials with broad spectrum of activity, carbapenems and fluoroquinolones. LÄS MER

  4. 8. On extrinsic and intrinsic organizational themes in gram negative bacteria and their role in evolution and virulence of the bacterial genus Salmonella spp

    Författare :Anders Folkesson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Salmonella; fimbriae; evolution; cell wall; peptidoglycan;

    Sammanfattning : Gram-negative bacteria are composed of intrinsic organizational themes such as outer and inner membrane, cell wall, and replicons. Themes that not only determine the body-plan and physical properties but also set the boundaries for choice of life style and evolution of the organisms. LÄS MER

  5. 9. Role of HAMLET and metabolism in treatment and pathogenesis of pneumococci

    Författare :Goutham Vansarla; Malmö Experimentell infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Streptococcus pneumoniae; Antibiotic resistance; Alpha-lactalbumin; HAMLET; Biofilms; Bacterial metabolism; Immunomodulatory effects.;

    Sammanfattning : Antimicrobial resistance (AMR) is one of the principle public health problems in the 21st century, threatening the available treatment strategies for bacterial infections. Here, we present a human protein-lipid complex, HAMLET (human alpha-lactalbumin made lethal to tumor cells) purified from human milk as a potential therapeutic agent which has both tumoricidal and bactericidal activity.

  7. 10. Interactions between Bacteria and Fungi on Aquatic Detritus – Causes and Consequences

    Författare :Cecilia Mille-Lindblom; Lars Tranvik; Helmut Fischer; Eric Chauvet; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; bacteria; fungi; decomposition; antagonism; extracellular enzymes; competition; macrophytes; dissolved organic carbon DOC ; ergosterol; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : Bacteria and fungi dominate the decomposition of aquatic plants, a major process in the carbon and nutrient cycling in many aquatic systems. Although phylogenetically distant, bacteria and fungi often live in close proximity with each other. Since these microorganisms also have similar ecological functions, interactions have developed between them. LÄS MER
