1. 6. Bacterial colonization of the neonatal bowel and ileal pouch with focus on E. coli

   Författare :Anna Östblom; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; E. coli; persistens; intestinal microbiota; colonization; ileal pouch; persistence; virulence factor genes;

   Sammanfattning : The colonic microbiota is a source of inflammatogenic and potentially pathogenic bacteria, but also a source of immune maturation signals to the infant. Here, we have investigated the normal colonic microbiota, with focus on E. coli in Swedish and Pakistani newborn infants, as well as the microbiota of the ileo-anal pouch in colectomized patients.

3. 7. The Colonization Strategies of Nontypeable Haemophilus influenzae - Bacterial Colonization Factors and Vaccine Development

   Författare :Farshid Jalalvand; Malmö Klinisk mikrobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ABC-transporter; bacterial colonization; Haemophilus influenzae; Haemophilus Protein F; laminin; NTHi; pathogenesis; vaccine; virulence; vitronectin.;

   Sammanfattning : Nontypeable Haemophilus influenzae (NTHi) is a remarkably proficient colonizer of the human respiratory tract. The aim of this thesis has been to characterize currently known, and identify novel, bacterial factors involved in the key processes of colonization and pathogenesis, namely adherence to host tissue and evasion of the host innate immunity.

4. 8. Breast-feeding, nasopharyngeal colonization and otitis media

   Författare :Gustaf Aniansson; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cleft palate.; URI; SOM; AOM; otitis media; H. influenzae; S. pneumoniae; Breast-feeding; nasopharyngeal colonization; Immunology; serology; transplantation; Immunologi; serologi;

   Sammanfattning : This thesis analyzed the relationship between breastfeeding, nasopharyngeal colonization and acute otitis media (AOM) in children. Nasopharyngeal cultures were collected from 400 children and milk samples from their mothers in connection with the scheduled visits to well baby clinics at 1-3, 4-7 and 8-12 months of age, and episodes of AOM and URI were documented.

5. 9. Immune maturation and lymphocyte characteristics in relation to early gut bacteria exposure

   Författare :Sophia Björkander; Eva Sverremark Ekström; Hanne Frøkiær; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Allergy; cell-free supernatant; chemokines; colonization; cytokines; FOXP3; immune-maturation; lactobacilli; lymphocytes; NK-cells; Staphylococcus aureus; unconventional T-cells; molekylär biovetenskap; Molecular Bioscience;

   Sammanfattning : At birth, the immune system is immature and the gut microbiota influences immune maturation. Staphylococcus aureus (S. aureus) and lactobacilli are part of the neonatal gut microbiota and have seemingly opposite effects on the immune system. S. LÄS MER

7. 10. Negotiating Imperial Rule : Colonists and Marriage in the Nineteenth-century Black Sea Steppe

   Författare :Julia Malitska; Per Bolin; Mark Bassin; Ulla Rosén; Södertörns högskola; []

   Sammanfattning : After falling under the power of the Russian Crown, the Northern Black Sea steppe from the end of eighteenth century crystallized as the Russian government’s prime venue for socioeconomic and sociocultural reinvention and colonization. Vast ethnic, sociocultural and even ecological changes followed. LÄS MER
