  1. 21. Identification and Characterization of the Moraxella catarrhalis IgD-binding Protein MID

    Författare :Andrea Möllenkvist; Malmö Klinisk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; receptor; structure; phase variation; MID; IgD; Moraxella catarrhalis; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Moraxella catarrhalis is now an established human pathogen that frequently colonizes the upper respiratory tract causing most importantly otitis media in children. It has also been associated with sinusitis, laryngitis and lower respiratory tract infections in adults with predisposing conditions such as chronic obstructive pulmonary disease (COPD). LÄS MER

  3. 22. Linking innate and adaptive immunity to streptococcus pneumoniae

    Författare :Marie Olliver; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Streptococcus pneumoniae (the pneumococcus) most commonly colonizes the human nasopharyngeal mucosa without causing any symptoms. However, this organism has the potential to spread to normally sterile sites and cause pneumonia, meningitis or sepsis; diseases which are characterized by excessive inflammation. LÄS MER

  4. 23. Molecular and microscopical analysis of pathogenic streptococci - studies on surface proteins interacting with human cells and extracellular matrix

    Författare :Marta Bober; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Streptococcus pyogenes; streptococcal leucine rich repeat protein; M protein; collagen; keratinocytes;

    Sammanfattning : Association to specific host tissue structures allows pathogenic bacteria to establish an infection and facilitates the spread within its host. Interactions between bacterial surface structures and human proteins might determine the outcome of the infection. Streptococcus pyogenes (S. LÄS MER

  5. 24. Cellular receptors for viruses with ocular tropism

    Författare :Emma C Nilsson; Niklas Arnberg; Eric J Kremer; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adenovirus; picornavirus; receptors; antivirals; Virology; Virologi; molekylärbiologi; Molecular Biology; Infectious Diseases; infektionssjukdomar; mikrobiologi; Microbiology;

    Sammanfattning : Several viruses from different virus families are known to cause ocular infections, e.g. members of the Adenoviridae, Picornaviridae and the Herpesviridae families. These infections are spread by contact and in the case of adenoviruses (Ads) and picornaviruses they are also highly contagious. LÄS MER

  7. 25. Structural and genetic characterization of lipopolysaccharides extracted from disease causing non-typeable Haemophilus influenzae strains

    Författare :Mikael Engskog; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This thesis deals with the structure and genetic blueprint of lipopolysaccharides (LPS) expressed by the Gram-negative bacterium Haemophilus influenzae (H.influenzae). H. influenzae is an opportunistic pathogen that regularly colonizes the upper respiratory tract and exists in encapsulated (typeable) or nonencapsulated (non-typeable) forms (NTHi). LÄS MER
