11. 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
12. A forest dark : an evolutionary history of Norway spruce
Sammanfattning : Embedded within the relationships among species is a dense forest of gene trees, each with a potentially unique and discordant history. Such widespread genealogical heterogeneity is expected, but embracing this hierarchy of discordance while reconstructing the histories of populations and species remains a major challenge. LÄS MER
13. Genotypic and phenotypic characterization of Porphyromonas gingivalis in relation to virulence
Sammanfattning : The present thesis was designed to increase the knowledge on the role of pathogenic potential of Porphyromonas gingivalis as a putative periodontal pathogen. P. LÄS MER
14. Molecular and phenotypic characterization of diarrhoeagenic Escherichia coli from Nicaraguan children
Sammanfattning : Diarrhoeal diseases continue to be a foremost public health problem worldwide, with over 1.5 million deaths occurring each year, mostly in children in developing countries. In Nicaragua, the mortality due to diarrhoea in children less than 5 years of age is 11 per 10,000 inhabitants. LÄS MER
15. Phasing single DNA molecules with barcode linked sequencing
Sammanfattning : Elucidation of our genetic constituents has in the past decade predominately taken the form of short-read DNA sequencing. Revolutionary technology developments have enabled vast amounts of biological information to be obtained, but from a medical standpoint it has yet to live up to the promise of associating individual genotypes to phenotypic states of wide-spread clinical relevance.
