1. Adhesion-related interactions of Actinomyces and Streptococcus biofilm bacteria
Sammanfattning : Adhesion of bacteria is a key event in biofilm formation and is mediated by bacterial adhesins recognising host or bacterial partner receptors. In oral biofilm formation, primary Actinomyces and Streptococcus colonizers adhere to salivary pellicle proteins such as proline-rich proteins (PRPs) as well as to mucosal surfaces. LÄS MER
2. Responses to External Cues in Oral Bacteria
Sammanfattning : This thesis investigates responses to external cues in oral bacteria on a molecular level. Paper I maps Ser/Thr/Tyr phosphorylated proteins in relation to the general proteome in an oral commensal streptococcus (Streptococcus gordonii DL1). LÄS MER
3. Host ligands and oral bacterial adhesion : studies on phosphorylated polypeptides and gp-340 in saliva and milk
Sammanfattning : Infectious diseases e.g. gastric ulcer, caries and perodontitis, are caused by bacteria in a biofilm. Adhesion of bacteria to host ligands e. LÄS MER
4. The female genital tract microbiota: composition, relation to innate immune factors, and effects of contraceptives
Sammanfattning : Abnormal vaginal microbiota, as in bacterial vaginosis (BV), is associated with increased risk of obstetrical and gynaecologic complications and acquisition of sexually transmitted diseases. However, very little is known about the pathogenesis of BV. In BV, the normal vaginal Lactobacillus-dominated biota (LDB) is replaced by anaerobic bacteria. LÄS MER
5. Lactobacillus characterization and effects on oral biofilm composition
Sammanfattning : The human body is home for millions of bacteria. The largest microbial community is located in the gastro-intestinal (GI) tract, including the oral cavity with >700 identified taxa. Lactobacillus, which is normal inhabitant of the GI tract, contributes to health by possible biofilm and immune modulation. LÄS MER
