  2. 1. Interactions of human C4BP with Bordetella pertussis and Streptococcus pyogenes

    Author : Karin Berggård; Lund Dermatologi och venereologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; M protein; antigenic variation; phagocytosis resistance; complement; C4b-binding protein C4BP ; Bordetella pertussis; Streptococcus pyogenes; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Many microorganisms have developed mechanisms to protect themselves against attack from the complement system of the host. One possible mechanism for a microorganism to evade complement attack is to bind a human complement regulator, which may allow the microorganism to down-regulate complement activation. READ MORE

  4. 2. Molecular detection and epidemiological studies of atypical bacteria causing respiratory tract infections

    Author : Karolina Gullsby; Kåre Bondeson; Björn Olsen; Puolakkainen Mirja; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chlamydia pneumoniae; Mycoplasma pneumoniae; Bordetella pertussis; real-time PCR; P1 typing; MLVA; whole-genome sequencing; macrolide resistance; molecular diagnostics; molecular epidemiology;

    Abstract : Respiratory infections are common causes of morbidity and mortality. Chlamydia pneumoniae, Mycoplasma pneumoniae and Bordetella pertussis cause respiratory infection, often with similar symptoms. Molecular diagnostic methods are preferred since these bacteria are difficult to culture. READ MORE

  5. 3. Immunopathogenesis of Gai2-deficient mice. A model of inflammatory bowel disease

    Author : Lena Öhman; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Inflammatory Bowel Disease; Mucosa; Apoptosis; Bordetella pertussis; G-protein;

    Abstract : The intestinal mucosa is the largest lymphoid organ in the body, and it simultaneously has to protect us from any pathogen that might enter the gastrointestinal tract as well as maintaining tolerance to most antigens, mainly in the form of dietary constituents and microbial products. A dysfunctional control of local intestinal immune responses may lead to development of Inflammatory Bowel Disease (IBD) - the common name for ulcerative colitis (UC) and Crohn´s disease (CD).

  6. 4. Epidemiological characterisation of Bordatella pertussis in Sweden, 1970-2004

    Author : Abdolreza Advani; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Worldwide, Bordetella pertussis causes some 50 million cases of pertussis, and an estimated 2-300,000 fatalities each year. In Sweden vaccination against pertussis was introduced in the 1950s using diphtheria-tetanus-whole-cell pertussis vaccine (DTPw) until 1979, when it was withdrawn due to concerns about effectiveness.

  7. 5. Respiratory tract infections, reflex apnea and sudden infant death : experimental and epidemiological studies with special reference to respiratory syncytial virus, Bordetella pertussis and sleep position

    Author : Carl Lindgren; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Bordetella pertussis; Infection; Interleukins; Laryngeal chemoreflex; Respiratory syncytial virus; Reflex apnea; Sleep; Sleeping position; Sudden infant death;

    Abstract : The seasonal distribution of Sudden infant death syndrome (SIDS) followed the prevalence of respiratory tract infections (RTI) when prone sleeping position was recommended, but this covariation has recently been attenuated. Airway infections in the young infant are known to produce respiratory disturbances. READ MORE
