21. Diagnostic methods for bacterial etiology in adult community-acquired pneumonia
Sammanfattning : The etiologic agent is often unidentified in patients with community-acquired pneumonia (CAP). Development of new diagnostic methods has been encouraged. We aimed to develop a multiplex PCR (mPCR) assay for common bacterial pathogens and evaluate the diagnostic usefulness of this assay and of respiratory culture in CAP. LÄS MER
22. DNA vaccines and bacterial DNA in immunity
Sammanfattning : This thesis describes DNA-based vaccination and the importance of bacterial DNA in different immunological perspectives. Intranasal (i.n.) DNA vaccination utilizing a plasmid encoding the chlamydial heat shock protein 60 (p-hsp-60) generated lower bacterial burden and reduced pathology in the lungs of mice after subsequent infection with C.

23. Host control of intracellular bacterial infections
Sammanfattning : In this thesis various immune mechanisms regulating control of infections with the intracellular bacteria Listeria monocytogenes and Chlamydia pneumoniae have been studied. These bacteria infect macrophages in which they can successfully grow. However, macrophages are potent killers of intracellular bacteria. LÄS MER
24. Molecular and microscopical analysis of pathogenic streptococci - studies on surface proteins interacting with human cells and extracellular matrix
Sammanfattning : Association to specific host tissue structures allows pathogenic bacteria to establish an infection and facilitates the spread within its host. Interactions between bacterial surface structures and human proteins might determine the outcome of the infection. Streptococcus pyogenes (S. LÄS MER
25. Structural studies of bacterial polysaccharides using N.M.R. spectroscopy and mass spectrometry
Sammanfattning : This work describes the structural studies of the capsularpolysaccharides from Streptococcus pneumoniae type 18F and 7B,Alcaligenes ATCC 31961 (S-194), and the O-antigen polysaccharidefrom Vibrio cholerae 0:3.The principal methods used in these studies were ID and 2D n.m.r. LÄS MER
