11. Pathogenecity-associated genes modulate Escherichia coli adhesion and motility
Sammanfattning : Escherichia coli strains typical of UPEC (uropathogenic E. coli) and NBM (newborn meningitis) isolates carry chromosomally located PAIs (pathogenicity islands) that are absent in non-pathogenic E. coli strains. The PAIs include genes for virulence factors such as toxins and genes coding for specific adhesins and pili/fimbriae formation. LÄS MER
12. Colonization, persistence and virulence factors in Escherichia coli strains in the human intestinal microflora
Sammanfattning : Escherichia coli is a member of the normal intestinal microflora of man and many animals. In this thesis, various aspects of the E. coli colonization pattern were studied, especially the role of so called virulence factors for persistence of E. coli in the gut microflora. LÄS MER
13. Characterization of Escherichia coli colonizing the gastrointestinal tract and urinary tract catheters
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
14. Modulaton of gene expression in human aortic smooth muscle cells by Porphyromonas gingivalis : a possible association between periodontitis and atherosclerosis
Sammanfattning : Porphyromonas gingivalis is a gram-negative, rod-shaped, and anaerobic bacterium that is involved in the pathogenesis of periodontitis. P. gingivalis produces a variety of virulence factors including gingipains and fimbriae. LÄS MER
15. Adhesion-related interactions of Actinomyces and Streptococcus biofilm bacteria
Sammanfattning : Adhesion of bacteria is a key event in biofilm formation and is mediated by bacterial adhesins recognising host or bacterial partner receptors. In oral biofilm formation, primary Actinomyces and Streptococcus colonizers adhere to salivary pellicle proteins such as proline-rich proteins (PRPs) as well as to mucosal surfaces. LÄS MER
