6. A strategy to identify novel antimicrobial compounds : a bioinformatics and HTS approach
Sammanfattning : Bacterial infections are again becoming difficult to treat because the microbes are growing increasingly resistant to the antibiotics in use today. The need for novel antimicrobial compounds is urgent and to achieve this new targets are crucial. In this thesis we present a strategy for identification of such targets via a bioinformatics approach. LÄS MER
7. The accessory gene regulator, agr, a system for coordinate control of virulence genes in Staphylococcus aureus
Sammanfattning : Bacterial pathogenicity is generally multifactorial, and genes encoding virulence factors are often subject to coordinate regulation. The regulating systems are supposed to adapt the production of virulence factors in response to changes in the environment during the process of infection. LÄS MER
8. Genetic approaches towards understanding penumococcal virulence and biology
Sammanfattning : Streptococcus pneumoniae, the pneumococcus, is a major human pathogen giving rise to death and illness worldwide every year. It causes a wide variety of diseases, from normally harmless infections such as otitis media to potentially life-threatening systemic diseases such as pneumonia, meningitis and sepsis. LÄS MER
9. Modulators of Vibrio cholerae predator interaction and virulence
Sammanfattning : Vibrio cholerae, the causal agent of cholera typically encodes two critical virulence factors: cholera toxin (CT), which is primarily responsible for the diarrhoeal purge, and toxin-co-regulated pilus (TCP), an essential colonisation factor. Nontoxigenic strains expressing TCP can efficiently acquire the CT gene through lysogenic conversion with CTXΦ, a filamentous phage that encodes CT and uses TCP as a receptor. LÄS MER
10. 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
