  1. 1. Recurrent Streptococcal Pharyngotonsillitis Studies on etiology and treatment

    Detta är en avhandling från Lund University

    Författare :Arne Orrling; [2006]
    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

  2. 2. Streptococcal M protein and human C4BP

    Detta är en avhandling från Department of Laboratory Medicine, Lund University

    Författare :Jenny J Persson; [2006]
    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

  3. 3. Group B streptococcal infections in neonates : Clinical and pathogenic aspects

    Detta är en avhandling från Linköping : Linköpings universitet

  5. 5. Interactions between streptococcal M proteins and human plasma proteins

    Detta är en avhandling från Department of Laboratory Medicine, Lund University

    Författare :Charlotta Sandin; [2005]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infektioner; Infections; innate immunity; Streptococcus pyogenes; phagocytosis resistance;

    Sammanfattning : Streptococcus pyogenes is a common human pathogen, which causes a variety of diseases. A major virulence factor of S. pyogenes is the surface-associated M protein, which mediates resistance to phagocytosis. Several studies indicate that M proteins inhibit complement deposition and thereby phagocytosis. LÄS MER
