    Sammanfattning : Streptococcus pyogenes is an important human pathogen frequently colonizing the throat and skin of humans. To facilitate colonization and spread and to avoid the host immune defence, streptococci are endowed with a variety of virulence factors, two of which are investigated in this thesis namely streptolysin O (SLO) and M protein.

  3. 22. TRANSMISSION AND PATHOGENESIS OF HANTAVIRUS

    Författare :Lisa Pettersson; Magnus Evander; Clas Ahlm; Annika Allard; Tatjana Avšič - Županc; Umeå universitet; []
    Nyckelord :Puumala virus; Hantavirus; human-to-human transmission; saliva; nephropathia epidemica; NE; IgA; IgG; IgM; neutrophils; neutrophil; viremia; treatment; climate; snow cover; temperature.; medicinsk virologi; Medical Virology;

    Sammanfattning : Hantaviruses are the causative agents of hemorrhagic fever with renal syndrome (HFRS) in Eurasia, and of hantavirus cardiopulmonary syndrome (HCPS) in the Americas. Transmission to humans usually occurs by inhalation of aerosolized virus-contaminated rodent excreta. LÄS MER

  4. 23. Neisseria gonorrhoeae and Lactobacillus from initial adherence to effects on human cells

    Författare :Katarina Vielfort; Helena Aro; Bernt Eric Uhlin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neisseria gonorrhoeae; Lactobacillus; adhesion; cell cycle; DNA damage; Neutrophils; molekylärgenetik; Molecular Genetics;

    Sammanfattning : The causative agent of gonorrhoea Neisseria gonorrhoeae (gonococcus) colonises the urogenital tract epithelia. The vaginal tract microbiota of healthy females is dominated by Lactobacillus species. In paper I, the ability of lactobacilli to protect cervical cells against gonococcal adherence was investigated.

  5. 24. PACAP and airway regulation with special reference to smooth muscle and neutrophils

    Författare :Johan Kinhult; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; audiology; auditive system and speech; Otorinolaryngologi; audiologi; hörsel- och talorganen; Otorhinolaryngology; allergy; neutrophils; smooth muscle; PACAP; airway regulation;

    Sammanfattning : The investigations focus on the neuropeptidepituitary adenylate cyclase-activating peptide and its effects on airway regulation, with emphasis on smooth muscle relaxation and neutrophil activation and migration. In the nasal mucosa, PACAP-containing nerve fibers were localized invascular smooth muscle and close to seromucous glands. LÄS MER

  7. 25. Escherichia coli Fimbriae, Bacterial Persistence and Host Response Induction in the Human Urinary Tract

    Författare :Göran Bergsten; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mykologi; virologi; bakteriologi; Mikrobiologi; mycology; virology; bacteriology; Microbiology; IL-8; IL-6; neutrophils; GFP; mucosal host response; Type 1 fimbriae; P fimbriae; adherence; virulence factors; regulation; deliberate colonisation; Escherichia coli 83972; Urinary tract infection; asymptomatic bacteriuria;

    Sammanfattning : Urinary tract infections (UTI) are among the most common bacterial infections in humans. Symptomatic UTIs may be acute, recurrent or chronic but the most frequent form of UTI is asymptomatic bacteruria (ABU). In ABU, the mucosa remains inert, despite the presence of large bacterial numbers in urine. LÄS MER
