  1. 1. Epidemiological aspects of tuberculosis in Guinea-Bissau, West Africa

    Författare :Per Gustafson; Enheten för infektionssjukdomar; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tuberculin skin test; Infections; Infektioner; survival; mortality; case fatality rate; risk factor; incidence; Guinea-Bissau; Africa; epidemiology; Mycobacterium tuberculosis; HIV-2; HIV-1; HIV; Tbc; Tuberculosis; TB;

    Sammanfattning : Tuberculosis (TB) has plagued the humanity for several thousands of years. The bacteria causing TB is mainly spread from person to person as an aerosol transmission. It is estimated that one third of the world’s population is infected with the disease; about 10% of these will develop active TB during their lifetime. LÄS MER

  3. 2. Fighting Tuberculosis – : Structural Studies of Three Mycobacterial Proteins

    Författare :Alina Castell; Torsten Unge; Manfred Weiss; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mycobacterium tuberculosis; Rv0216; Rv0130; Mycobacterium smegmatis; branched chain aminotransferase; X-ray crystallography; fatty acid metabolism; Structural biology; Strukturbiologi;

    Sammanfattning : This thesis presents the cloning, purification, crystallization, and structural studies of two unknown proteins from Mycobacterium tuberculosis, and of an aminotransferase from Mycobacterium smegmatis. Structural knowledge of these proteins is of highest interest for structure-based drug design, which is one of the approaches that can be used in order to fight tuberculosis (TB). LÄS MER

  4. 3. Dynamics of tuberculosis infection in Sweden

    Författare :Niclas Winqvist; Enheten för infektionssjukdomar; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tuberculosis; latent tuberculosis infection; long-term follow-up; Øresund region; interferon-gamma release assay; tuberculin skin test;

    Sammanfattning : Sweden provides a special setting for epidemiological and demographic studies of tuberculosis (TB) infection over time for principally two reasons; first, the Swedish TB epidemic has undergone a tremendous transition since the end of the 19th century, when TB was highly endemic, to the current situation with practically interrupted indigenous transmission since several decades. Second, an increasing proportion of persons who grew up before TB transmission virtually disappeared in the 1960s are reaching advanced age, and thus creating conditions that predispose to reactivation of latent TB infection (LTBI).

    Sammanfattning : Mycobacterium tuberculosis (Mtb) is the pathogen causing tuberculosis (TB), a disease most often affecting the lung. 1.5 million people die annually due to TB, mainly in low-income countries. LÄS MER

  7. 5. Aspects of Tuberculosis and HIV Coinfection in Patients at Ethiopian Health Centers

    Författare :Sten Skogmar; Enheten för infektionssjukdomar; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HIV; TB; clinical scoring; TB screening; CD4 cell count; immunosuppression; immune activation;

    Sammanfattning : HIV and tuberculosis (TB) remain the two most common infectious causes of death worldwide. During the recent decade antiretroviral treatment (ART) has become available for millions of people living with HIV (PLHIV) globally; yet more than half of PLHIV have not yet initiated ART. LÄS MER
