  1. 1. Streptococcal immunoglobulin degrading enzymes of the IdeS and IgdE family

    Författare :Christian Spoerry; Ulrich von Pawel-Rammingen; Heiko Herwald; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Streptococcus; S. pyogenes; S. agalactiae; S. suis; S. porcinus; S. pseudoporcinus; S. equi subsp. zooepidemicus; protease; immunoglobulin; immune evasion; IdeS; IgdE; molekylärbiologi; Molecular Biology;

    Sammanfattning : Bacteria of the genus Streptococcus are common asymptomatic colonisers of humans and animals. As opportunistic pathogens they can however, depending on their host’s immune status and other circumstances, cause mild to very severe infections. LÄS MER

  3. 2. Molecular epidemiology of streptococcus agalactiae : mobile elements as genetic markers

    Författare :Shi-Lu Luan; Mari Norgren; Barbara Spellerberg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Streptococcus agalactiae; group II intron GBSi1 ; multilocus sequence typing; capsular serotype; population structure; Clinical bacteriology; Klinisk bakteriologi;

    Sammanfattning : Streptococcus agalactiae, also designated group B streptococcus (GBS), is a Gram-positive coccus, and it is an important pathogen that causes invasive disease in neonates, pregnant adults, and non-pregnant adults with predisposing conditions. The group II intron GBSi1 is one of the major mobile genetic elements identified in S. agalactiae. LÄS MER

  4. 3. Molecular studies on streptococcal surface proteins

    Författare :Johan Waldemarsson; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nonimmunodominance; vaccine; camouflaging; Streptococcus agalactiae; leucine-rich repeat; Streptococcus pyogenes; alpha; fibrinogen; M protein; surface proteins; Rib;

    Sammanfattning : Streptococcus agalactiae and Streptococcus pyogenes are two related human pathogens causing different diseases. This thesis focuses on a number of surface proteins expressed by S. agalactiae and S. pyogenes and, more specifically, the molecular and biological characterization of these proteins. LÄS MER

  5. 4. Bioinformatics analysis of bacterial pathogens from East African camels : comparative genomics of Streptococcus agalactiae and Staphylococcus aureus

    Författare :Saima Zubair; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The camel is the most valuable livestock species in arid and semi-arid regions in the Greater Horn of Africa. Streptococcus agalactiae and Staphylococcus aureus are important pathogens for a wide range of hosts including camels, cattle and humans. LÄS MER

  7. 5. Surface proteins of pathogenic streptococci

    Författare :Thomas Areschoug; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi; Microbiology; factor H; complement regulator; CD89; human IgA; protective immunity; surface protein; Streptococcus pyogenes; group B streptococcus;

    Sammanfattning : Streptococcus pyogenes (group A streptococcus) and the group B streptococcus (GBS) are two important human pathogens that cause different types of diseases and express different surface structures implicated in virulence. This thesis focuses on several surface proteins expressed by these pathogens, analyzing the biological function of these proteins and their ability to elicit protective immunity. LÄS MER
