  1. 11. Antimicrobial peptides as defense molecules at the interface of the host and bacteria

    Författare :Ulf Meyer-Hoffert; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Microbes surround us. However, most of the time we are unaware of them. Our epithelial surfaces, which provide the physical barrier and separate us from the environment, are usually free of signs of a battle taking place. LÄS MER

  3. 12. Antibiotic resistance and pathogenesis of Streptococci with focus on Group A Streptococci

    Författare :Feiruz Alamiri; Malmö Experimentell infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antibiotika resistens; Bröstmjölk; Luftvägsinfektioner; Biofilm bildning; Internalisering; Persistens; HAMLET; Streptokocker; kolonisering; Streptococcus pneumoniae; biofilm formation; Internalisation; Persistence; Antibiotic resistance; Streptococcus pyogenes; Streptococcus agalactiae; HAMLET; Breast milk; Proteome; Virulence factors; Colonization;

    Sammanfattning : Multi-drug resistant (MDR) infections remain the leading cause of death worldwide. MDR infections caused by Streptococcus pneumoniae (Spn), Streptococcus pyogenes (GAS) and Streptococcus agalactiae (GBS) are considered global threats to human health due to increased spread of antibiotic resistance and limited treatment options.

  4. 13. On cobalt-chrome frameworks in implant dentistry

    Författare :Lars Hjalmarsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cobalt-chrome; titanium; implants; misfit; corrosion; viability; abutment-free;

    Sammanfattning : Background: Cobalt-chrome (CoCr) alloys have been used in dentistry in decades but very little is known about their behavior and biological impact as framework materials in implant dentistry. Furthermore, few studies have evaluated and compared the clinical and radiological results of abutment and abutment-free implant treatment concepts. LÄS MER

  5. 14. Characterization of Escherichia coli colonizing the gastrointestinal tract and urinary tract catheters

    Författare :Xiaoda Wang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Commensal and pathogenic bacteria express biofilm behaviour which is thought to alter bacteria-host interactions and contribute to colonization and persistence. In the current thesis, the epidemiology of biofilm formation in gastrointestinal commensal Escherichia coli and E. coli isolated from urinary catheters is described. LÄS MER

  7. 15. Assembly and proteolytic cleavages of gel-forming mucins

    Författare :Martin Lidell; Göteborgs universitet; []
    Nyckelord :mucins; MUC2; MUC5AC; dimer; trimer; cleavage; Entamoeba histolytica; cysteine protease;

    Sammanfattning : Gel-forming mucins are large glycoproteins constituting the main structural component of themucus layer protecting epithelial surfaces of the body. This thesis aims to a deeper understandingof how gel-forming mucins are synthesized and assembled, and how they may interact with othermolecules. LÄS MER
