    Sammanfattning : Chlamydia trachomatis is an obligate intracellular bacterium that infects over 100 million people globally every year. Chlamydia infections can be persistent, cause infertility and blindness, adding an economical burden in the healthcare systems. LÄS MER

  3. 12. Recurrent pain and health related quality of life in young schoolchildren

    Författare :Solveig Petersen; Erik Bergström; Bruno Hägglöf; Sven Bremberg; Umeå universitet; []
    Nyckelord :Pediatrics; Abdominal pain; Back pain; Child; Headache; Pain; Psychometrics; Quality of Life; Schools; validation studies; Pediatrik; pediatrik; Pediatrics;

    Sammanfattning : The objectives of this thesis were 1) to describe the occurrence and co-occurrence of recurrent pain (headache, stomach-ache, and backache) in young school children; 2) to describe Health Related Quality of Life (HRQoL) in these children, from the perspective of the child, 3) to examine the psychometric properties of the PedsQL, a pediatric HRQoL instrument. Three data collections were performed, two in Umeå, Sweden, and one in a nearby smaller municipality, Lycksele. LÄS MER

  4. 13. The Origin of the Genus Flavivirus and the Ecology of Tick-Borne Pathogens

    Författare :John H.-O. Pettersson; Thomas Jaenson; Sven Bergström; Kenneth Nilsson; Mikael Thollesson; Per-Eric Lindgren; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Flavivirus; Virus dating; Molecular dating; Biogeography; Ixodes ricinus; Minimum infection rate; TBE; Tick-borne encephalitis virus; Rickettsia helvetica; Anaplasma phagocytophilum; Infection prevalence; RT-PCR; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Sammanfattning : The present thesis examines questions related to the temporal origin of the Flavivirus genus and the ecology of tick-borne pathogens. In the first study, we date the origin and divergence time of the Flavivirus genus. It has been argued that the first flaviviruses originated after the last glacial maximum. LÄS MER

  5. 14. Porins of Borrelia burgdorferi

    Författare :Marija Pinne; Sven Bergström; Magnus Höök; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lyme disease; P13; paralog; P66; channel-forming activity; porin; Medical microbiology; Medicinsk mikrobiologi;

    Sammanfattning : Borrelia burgdorferi is a pathogenic spirochete which cycles between its arthropod vector and vertebrate host. If transmitted to humans, B. burgdorferi causes Lyme disease, an infection which can impair different organs, such as the skin, joints, nervous system and heart. LÄS MER

  7. 15. A STING from a Tick : Epidemiology, Ecology and Clinical Aspects of Lyme Borreliosis

    Författare :Peter Wilhelmsson; Per-Eric Lindgren; Pia Forsberg; Sven Bergström; Christina Ekerfelt; Jeremy S. Gray; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Lyme borreliosis (LB) is the most common tick-borne disease in the Northern Hemisphere and the number of LB cases is increasing. The infection is caused by spirochetes belonging to the Borrelia burgdorferi sensu lato complex, and is, in Europe, transmitted to humans by Ixodes ricinus ticks. LÄS MER
