  1. 6. Characterization of surface components of Moraxella catarrhalis and pathogenic Neisseria

    Författare :Motiur Rahman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Moraxella catarrhalisantibody LPS NeisseriapiliPilC;

    Sammanfattning : Infection is a multistep process including adhesion, colonisation, invasion and multiplication which finally results in disease. Bacterial surface components and virulence factors are essential for all these different steps and they are co-ordinately regulated during the different steps of pathogenesis and infection. LÄS MER

  3. 7. Bacterial Outer Membrane Vesicles. Mediators of virulence and antibiotic resistance

    Författare :Viveka Schaar; Malmö Klinisk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antibiotic resistance; Moraxella catarrhalis; epithelial cells; beta-lactamase; non-typeable Haemophilus influenzae; outer membrane vesicles; polymicrobial infections; UspA1;

    Sammanfattning : Outer membrane vesicles (OMV) have the size of nanoparticles and are released from the outer membrane of most Gram-negative bacteria. The OMV reflect the composition of the bacterial outer membrane, including lipids and virulence factors specific for the pathogen, and are involved in pathogenesis and bacterial survival. LÄS MER

  4. 8. Experimental acute otitis media : aspects on treatment, protection and structural changes

    Författare :Eva Westman; Ann Hermansson; Sten Hellström; Åsa Melhus; Bengt Carlsöö; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Otorhinolaryngology; acute otitis media; penicillins; rat; treatment; protection; beta-lactamase; Moraxella catarrhalis; Haemophilus influenzae; Otorhinolaryngologi; Otorhinolaryngology; Otorhinolaryngologi; Oto-Rhino-Laryngology; oto-rhino-laryngologi;

    Sammanfattning : Acute otitis media (AOM) is a common disease in childhood and is one of the most common causes for outpatient antibiotic treatment. The major aetiological agents of AOM have varied over the decades. Now the three most common pathogens are Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis. LÄS MER

  5. 9. MORAXELLA CATARRHALIS OUTER MEMBRANE PROTEINS AND THEIR INTERACTIONS WITH THE HUMAN HOST

    Författare :Thuan Tong Tan; Malmö Klinisk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mikrobiologi; bakteriologi; virologi; mykologi; virology; mycology; Microbiology; bacteriology; MID; UspA1; UspA2;

    Sammanfattning : Moraxella catarrhalis is an airway pathogen whose role in infection has been increasingly recognized in recent years. Most authorities in this field now agree that M. catarrhalis causes significant morbidity and is not just a harmless commensal. The universal prevalence of BRO ?-lactamases in this pathogen is a serious concern. LÄS MER

  7. 10. Characterization of IgD-binding by respiratory pathogens

    Författare :Martin Samuelsson; Malmö Klinisk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; virology; mycology; H. influenzae; bacteriology; Microbiology; IgD-binding; M. catarrhalis; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : The focus of this thesis was to explore the interaction between IgD and Moraxella catarrhalis and Haemophilus influenzae. These two respiratory pathogens are responsible for otitis media in children, and exacerbations in patients afflicted with predisposing conditions such as chronic obstructive pulmonary disease (COPD). Both M. catarrhalis and H. LÄS MER
