  1. 31. Enterococci in Swedish intensive care units : studies on epidemiology, mechanisms of antibiotic resistance and virulence factors

    Författare :Anita Hällgren; Arnfinn Sundsfjord; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The purpose of this thesis was to study enterococci in Sweden, their resistance to antibiotics in general and high-level gentamicin resistance (HLGR) in particular, with a special focus on the ICU setting. Dynamics of rectal colonisation during prolonged intensive care unit (ICU) stay was assessed. LÄS MER

  3. 32. Haemophilus influenzae – typing, epidemiology and beta-lactam resistance

    Författare :Viktor Månsson; Malmö Klinisk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; benzylpenicillin; beta-lactam resistance; beta-lactams; BLNAR; capsule typing; clonal; Haemophiilus influenzae; Hib; MALDI-TOF MS; MLST; NTHi; serotyping; virulence; epidemiology;

    Sammanfattning : Haemophilus influenzae is a common cause of respiratory tract infections such as acute otitis media (AOM), exacerbations of chronic obstructive pulmonary disease (COPD) and pneumonia. The species is subdivided into encapsulated and non-encapsulated strains, designated type a-f and nontypeable H. influenzae (NTHi), respectively. LÄS MER

  4. 33. Exploration of factors that influence Plasmodium falciparum fitness and virulence

    Författare :Madle Sirel; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Malaria is an ancient disease that still has profound impact on human population. The virulence of the most lethal malaria parasite, Plasmodium falciparum, can be attributed to several features of the parasite. P. falciparum is known for its indiscriminate red blood cell (RBC) invasion and aptitude for cytoadherence. LÄS MER

  5. 34. Immunoglobulin-binding bacterial surface proteins; biomedical tools and virulence factors

    Författare :Britt-Marie Kihlberg; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Phagocytosis; M-like protein; M protein; Protein L; Protein G; Ig-binding; Streptococcus pyogenes; Fc Receptors; mykologi; virologi; bakteriologi; Mikrobiologi; mycology; virology; bacteriology; Microbiology; Cysteine proteinase; Streptolysin;

    Sammanfattning : Many bacteria express immunoglobulin(Ig)-binding proteins that interact with Ig in a non-immune manner. Several of these Ig-binding bacterial proteins have been well characterized and are widely used as reagents for analysis and purification of Ig's. LÄS MER

  7. 35. YopD translocator function in Yersinia pseudotuberculosis type III secretion

    Författare :Tiago R. D. Costa; Matthew S. Francis; William D. Picking; Umeå universitet; []
    Nyckelord :Y. pseudotuberculosis; T3SS; translocon; YopD; coiled-coil; effector delivery; regulation; virulence; mikrobiologi; Microbiology;

    Sammanfattning : Type III secretion systems (T3SS) are a common feature of Gram-negative bacteria, allowing them to inject anti-host effectors into the interior of infected eukaryotic cells. By this mechanism, these virulence factors help the bacteria to modulate eukaryotic cell function in its favor and subvert host innate immunity. LÄS MER
