  2. 1. Antibiotic Resistance and Population Dynamics of Escherichia coli in Relation to a Large Scale Antibiotic Consumption Intervention

    Author : Martin Sundqvist; Otto Cars; Gunnar Kahlmeter; Dan I Andersson; Jordi Vila; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reversibility; trimethoprim; dfr; associated resistance; MLST; Infectious diseases; Infektionssjukdomar; Clinical bacteriology; Klinisk bakteriologi; Medical microbiology; Medicinsk mikrobiologi; Infectious Diseases; Infektionssjukdomar;

    Abstract : Antibiotic resistance challenges the practice and development of modern medicine. The aim of this thesis was to test the hypothesis that antibiotic resistance is reversible once the selection pressure of an antibiotic is removed. READ MORE

  4. 2. Regulation of antimicrobial peptide gene expression in Drosophila melanogaster : Involvement of POU and NF-kB/Rel factors in innate immunity

    Author : Anna Junell; Ylva Engström; Jean-Luc Imler; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : The fruit fly, Drosophila melanogaster, has a well-developed immune response, and microbial assault induces a rapid production of potent antimicrobial peptides (AMPs). The aim of this thesis work was to gain deeper knowledge of the regulation of AMPs in Drosophila, by the isolation and characterization of transcription factors involved in AMP gene expression.

  5. 3. Molecular basis for trimethoprim and sulphonamide resistance in Gram negative pathogens

    Author : Malin Grape; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Resistance to antibiotics is becoming an important global public health problem. Infectious diseases are still among the major causes of disease and death in many parts of the world and the possibilities to treat bacterial infections are now threatened due to the spread of antibiotic resistance.

  6. 4. Signaling and transcriptional regulation of antimicrobial peptide genes in Drosophila melanogaster

    Author : Hanna Uvell; Ylva Engström; Won-Jae Lee; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; antimicrobial peptides; drosophila; immunity; transcriptiona regulation; Molecular biology; Molekylärbiologi;

    Abstract : Insects rely solely on innate immune reactions for protection against infect-ing microbes in their environment. In Drosophila, one major defense mechanism is the production of a battery of antimicrobial peptides (AMPs). READ MORE

  7. 5. Characterization of resistance to quinolones, sulfonamide and trimethoprim in Campylobacter jejuni as well as to macrolides in the related bacterium, Helicobacter pylori

    Author : Amera Gibreel; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; Pharmaceutical Microbiology; farmaceutisk mikrobiologi;

    Abstract : Gastroenteritis caused by C. jejuni is usually a mild to moderate self-limiting disease. Treatment is recommended in some cases. In recent years, quinolones have been increasingly used to treat acute bacterial enteritis. READ MORE
