  1. 16. Antimicrobial potential of Geobacillus sp. ZGt-1 isolated from Zara hot spring in Jordan : Piecing the puzzle of the antagonistic activity of a novel bacterial strain

    Författare :Rawana Alkhalili; Bioteknik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thermophiles; Geobacillus; antimicrobial potential; antimicrobial peptides; bacteriocins; lanthipeptides; toxin-antitoxin; genome sequence;

    Sammanfattning : The problem of antibiotic resistance is rising continuously, creating a warning signal that calls for finding alternatives. Not only that, but there is also a rising demand for natural food preservatives. The pharmaceutical and food industry sectors are working on fulfilling these needs. This thesis is exploring possible solutions to these issues. LÄS MER

  2. 17. STRUCTURAL, FUNCTIONAL AND EVOLUTIONARY STUDIES OF ANTIMICROBIAL PEPTIDES

    Författare :Mukesh Pasupuleti; Lund Dermatologi och venereologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amphipathicity and end-tagging protease susceptibility; anaphylatoxin C3a; P. aeruginosa; S. aureus; innate immunity; amphipathic molecules; Antimicrobial peptides; infectious disease; bacteriostatic; microbicidal and cytolytic properties;

    Sammanfattning : Antimicrobial peptides represent a heterogeneous group that displays multiple modes of action such as bacteriostatic, microbicidal and cytolytic properties that are sequence and concentration dependent. Life threatening infectious disease is now a worldwide crisis and treating them effectively is becoming difficult day by day, due to the emergence of antibiotic resistant strains at alarming rates.

  3. 18. Bacteria-host cell interactions : Studies on initial colonization, antimicrobial peptides, and biofilms

    Författare :Gabriela Wassing; Ann-Beth Jonsson; Elena Vikström; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Neisseria meningitidis; Lactobacillus; host responses; EGR1; antimicrobial peptides; hBD2; A20; biofilm; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : The obligate human pathogen Neisseria meningitidis asymptomatically colonizes the upper respiratory tract, but crossing of the epithelial barrier can cause life-threatening meningitis and/or sepsis. N. LÄS MER

  4. 19. Pathogenic Neisseria : Single cell motility, multicellular dynamics and antimicrobial susceptibility

    Författare :Olaspers Sara Eriksson; Ann-Beth Jonsson; Matthew Francis; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Neisseria; Type IV pili; Twitching motility; PilT; Microcolony dynamics; PilU; NafA; Antimicrobial peptide; Cell-penetrating peptide; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Neisseria meningitidis and Neisseria gonorrhoeae can colonize humans without causing any symptoms. However, gonorrhea and invasive meningococcal disease are serious health concerns. An essential virulence factor for neisserial adhesion to host cells, twitching motility and microcolony formation/aggregation is the retractile type IV pili (Tfp). LÄS MER

  5. 20. Actions of Antimicrobial Peptides and Bacterial Components in Inflammation

    Författare :Thorgerdur Sigurdardottir; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sepsis; LL-37; M1 protein; S. pyogenes; Toll-like receptors; phenylephrine; nitr1c oxide; antimicrobial peptides;

    Sammanfattning : Antimicrobial peptides are evolutionally ancient parts of the innate immune system and their primary role is to protect us from infections. The human cathelicidin-derived antimicrobial peptide, LL-37, not only possesses broad spectrum antimicrobial activities but is also able to bind and neutralize bacterial lipopolysaccharide (LPS), an important trigger of the widespread inflammatory response contributing to septic shock.
