  1. 16. Interaction Between Antimicrobial Peptides and Phospholipid Membranes : Effects of Peptide Length and Composition

    Författare :Lovisa Ringstad; Martin Malmsten; Per Hansson; Jeremy Ramsden; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adsorption; antibacterial; antimicrobial peptide; bilayer; ellipsometry; electrochemistry; electrostatic interactions; hydrophobicity; liposome; membrane; monolayer; phospholipid; secondary structure; supported bilayer.; PHARMACY; FARMACI; Pharmaceutical Physical Chemistry; farmaceutisk fysikalisk kemi;

    Sammanfattning : Due to increasing problems with bacterial resistance development, there is a growing need for identifying new types of antibiotics. Antimicrobial peptides constitute an interesting group of substances for this purpose, since they are believed to act mainly by disrupting the bacterial membrane, which is a fast and non-specific mechanism.

  2. 17. 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

  3. 18. STRUCTURAL, FUNCTIONAL AND EVOLUTIONARY STUDIES OF ANTIMICROBIAL PEPTIDES

    Författare :Mukesh Pasupuleti; Lund Dermatologi och venereologi; []
    Nyckelord :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.

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

    Författare :Gabriela Wassing; Ann-Beth Jonsson; Elena Vikström; Stockholms universitet; []
    Nyckelord :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

  5. 20. Pathogenic Neisseria : Single cell motility, multicellular dynamics and antimicrobial susceptibility

    Författare :Olaspers Sara Eriksson; Ann-Beth Jonsson; Matthew Francis; Stockholms universitet; []
    Nyckelord :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
