  2. 1. Improved diagnosis and prediction of community-acquired pneumonia

    Author : Alicia Edin; Anders F. Johansson; Anders Sjöstedt; Annika Allard; Thomas Schön; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Community-acquired pneumonia; infection; diagnosis; qPCR; metabolites; metabolomics;

    Abstract : Community-acquired pneumonia (CAP) is a major cause of morbidity and mortality worldwide. Although there is wide variation in the microbial etiology, CAP may manifest with similar symptoms, making institution of proper treatment challenging. READ MORE

  4. 2. Sex differences in immune response and sex hormone receptor expression in healthy individuals and during viral infection

    Author : Peik M. A. Brundin; Anders F. Johansson; Ivan Nalvarte; Carl-Johan Treutiger; Umeå universitet; []

    Abstract : There is sex-bias in morbidity and mortality from infectious diseases. Infections kill more men than women and several studies have pointed out differences in the immune system as a reason. The sex hormones estrogen, progesterone and testosterone all shape the effect of the immune response on multiple levels. READ MORE

  5. 3. Francisella tularensis: persistence, dissemination and source attribution : a theoretical and computational approach

    Author : Chinmay Kumar Dwibedi; Anders Johansson; Pär Larsson; Markus Antwerpen; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Francisella; genomics; evolution; microbial forensics; dispersal; persistence; mikrobiologi; Microbiology;

    Abstract : The bacterium Francisella tularensis causing tularemia in humans and other mammals displays little genetic diversity among genomes across temporal and spatial scales. F. tularensis infects humans with an extremely low infectious dose and causes natural seasonal tularemia outbreaks. READ MORE

  6. 4. Genetic genealogy and epidemiology of Francisella

    Author : Kerstin Svensson; Anders Johansson; Mats Forsman; Sam R. Telford III; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Francisella tularensis; tularemia; genotyping; epidemiology; GIS; Infectious diseases; Infektionssjukdomar; Infectious Diseases; infektionssjukdomar;

    Abstract : This thesis is about analyzing genetic differences among isolates of Francisella tularensis – the tularemia-causing bacterium. To elucidate how these bacterial isolates are related, and their geographical and genetic origins, I have developed typing assays for Francisella and used them to study the epidemiology of tularemia.

  7. 5. Stability of bacterial DNA in relation to microbial detection in teeth

    Author : Malin Brundin; Ulf Sjögren; Anders Johansson; David Figdor; Inge Fristad; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell-bound DNA; cell-death; dentine; DNA binding affinity; DNA decomposition; DNA preservation; extracellular DNA; hydroxyapatite; PCR; polymerase chain reaction; odontologi; Odontology;

    Abstract : The fate of DNA from dead cells is an important issue when interpreting results from root canal infections analysed by the PCR technique. DNA from dead bacterial cells is known to be detectable long time after cell death and its stability is dependent on many different factors. READ MORE
