11. Role of lactobacilli in Helicobacter pylori pathogenesis and host cell responses
Sammanfattning : Helicobacter pylori is well adapted to the harsh environment of the human stomach, allowing it to persistently colonize the gastric mucosa of at least 50% of the global population for decades. Long-term colonization induces chronic inflammation that can eventually lead to development of peptic ulcer and gastric cancer. LÄS MER
12. Production, Purification and Characterization of Antimicrobial Biomolecules from Potential Probiotic Lactic Acid Bacteria
Sammanfattning : Development and optimization of the production of lactic acid bacteria (LAB) and their attendant 'natural' inhibitors as biopreservatives to control undesirable bacteria currently remains a primary focus of several laboratories involved in research concerning food safety and quality. Strategies utilized to study incorporation of biopreservatives into food include either direct use of LAB-strains or use of a biopreservative preparation in the form of previously fermented product or use of semipurified, purified, or chemically synthesized bacteriocins.

13. Evolution of symbiotic lineages and the origin of new traits
Sammanfattning : This thesis focuses on the genomic study of symbionts of two different groups of hymenopterans: bees and ants. Both groups of insects have major ecological impact, and investigating their microbiomes increases our understanding of their health, diversity and evolution. LÄS MER
14. Bacteria-host cell interactions : Studies on initial colonization, antimicrobial peptides, and biofilms
Sammanfattning : The obligate human pathogen Neisseria meningitidis asymptomatically colonizes the upper respiratory tract, but crossing of the epithelial barrier can cause life-threatening meningitis and/or sepsis. N. LÄS MER
15. Host-bacteria interactions : Host cell responses and bacterial pathogenesis
Sammanfattning : Helicobacter pylori colonizes the human stomach, where it causes gastritis that may develop into peptic ulcer disease or cancer when left untreated. Neisseria gonorrhoeae colonizes the urogenital tract and causes the sexually transmitted disease gonorrhea. LÄS MER
