    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. LYME BORRELIOSIS Detection and identification of the infecting genotype

    Författare :Katharina Ornstein; Sektion III; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Parasitologi människa och djur ; Parasitology human and animal ; Infektioner; Infections; PCR; genospecies; Lyme borreliosis; Borrelia burgdorferi; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Lyme borreliosis is caused by the spirochete Borrelia burgdorferi sensu lato, a bacterium with a parasitic life-style, which is transmitted between hosts by the Ixodes tick-vector. Humans will incidentally become infected. The resulting illness can involve the skin, nervous system, joints and heart. LÄS MER

  4. 23. Recurrent Streptococcal Pharyngotonsillitis Studies on etiology and treatment

    Författare :Arne Orrling; Lund näs- och halssjukdomar Öron-; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; auditive system and speech; Otorinolaryngologi; Infektioner; Otorhinolaryngology; Infections; Clindamycin.; Penicillin tolerance; Tonsillar surface fluid; treatment failure; Group A streptococci; hörsel- och talorganen; audiologi; audiology; Recurrent streptococcal pharyngotonsillitis;

    Sammanfattning : In acute pharyngotonsillitis group A streptococci (GAS) is the etiological agent in 30-50% of cases. Phenoxymethylpenicillin (pcV) is the drug of choice in Sweden. However, the failure rate is as high as 5-25% and further pcV treatment is followed by still higher failure rates. The background of failures remains largely elusive. LÄS MER

  5. 24. Streptococcal M protein and human C4BP

    Författare :Jenny J Persson; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infektioner; Infections; Medicin människa och djur ; Medicine human and vertebrates ; human C4BP; M protein; antigenic variation; sequence variability; Streptococcus pyogenes; innate immunity;

    Sammanfattning : Antigenic variation of surface proteins allows microorganisms to evade the immune system of the infected host. This phenomenon represents an apparent paradox, because the variable protein must retain an important function, while its antigenic properties vary extensively. LÄS MER

  7. 25. Characterisation of the Microbial Community in Indoor Environments: a Chemical-Analytical Approach

    Författare :Aleksandra Sebastian; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; indoor air; microbial chemical markers; asthma; allergies; tobacco smoke; Infektioner; Infections;

    Sammanfattning : Inhalation of airborne microorganisms and their toxic components and products may induce a wide spectrum of acute and chronic airway manifestations. The study describes important capabilities of chemical marker analysis in defining human exposure to microorganisms in indoor environments. LÄS MER
