6. Molecular epidemiology of streptococcus agalactiae : mobile elements as genetic markers
Sammanfattning : Streptococcus agalactiae, also designated group B streptococcus (GBS), is a Gram-positive coccus, and it is an important pathogen that causes invasive disease in neonates, pregnant adults, and non-pregnant adults with predisposing conditions. The group II intron GBSi1 is one of the major mobile genetic elements identified in S. agalactiae. LÄS MER
7. Respiratory Tract Infections: Aspects of Aetiology, Virulence, and Communicable Disease Control
Sammanfattning : The paediatric nasopharyngeal flora is regarded as the largest reservoir for Streptococcus pneumoniae, and the carrier state is always antecedent to infection and a prerequisite for dispersion of these bacteria. Pneumococci are the predominant aetiology of bacterial respiratory tract infections and a major cause of morbidity and mortality, in the most severe cases due to invasive pneumococcal disease (IPD; mainly sepsis and meningitis).

8. Synthesis of oligosaccharides related to the capsular polysaccharide of Neisseria meningitidis serotype A
Sammanfattning : In order to find suitable stable vaccine candidates against Neisseria meningitidis group A, several structures related to the capsular polysaccharide have been synthesised. The first part of the thesis describes the synthesis of C-phosphonate analogues starting from glucose. LÄS MER
9. Development and evaluation of a subunit DIVA vaccine against bluetongue virus serotype 8 in cattle
Sammanfattning : Bluetongue virus (BTV) causes the primarily vector-borne bluetongue disease of ruminants, which poses a permanent threat to Europe since new serotypes and strains are frequently introduced. Vaccination of cattle is essential to control BTV outbreaks. LÄS MER
10. Synthesis of oligosaccharides related to the capsular polysaccharides of Streptococcus pneumoniae serotype 9 and of Cryptococcus neoformans
Sammanfattning : In the present investigation, synthesis of oligosaccharides corresponding to structural elements present in the capsular polysaccharides of Streptococcus pneumoniae and Cryptococcus neoformans has been achieved. The first two sections describe the synthesis of spacer-equipped oligosaccharides corresponding to structures from the CPS of Streptococcus pneumoniae serotypes 9N, 9A and 9L, the production of which involved synthetic challenges such as the construction of β-ManNAc and α-GlcA linkages.
