1. 1. Evolutionary trajectories of Klebsiella pneumoniae : From experimental biofilm evolution to a hospital outbreak

   Författare :Greta Zaborskytė; Linus Sandegren; Vaughn S. Cooper; Uppsala universitet; []
   Nyckelord :Klebsiella pneumoniae; evolution; experimental evolution; biofilms; infection; bacterial pathogens; Mikrobiologi; Microbiology;

   Sammanfattning : Bacterial evolution is closely intertwined with our lives. As their hosts, we shape how bacteria evolve by imposing numerous selective pressures during the time bacteria spend in our bodies. As a result, they adapt in various ways to colonize us or infect us better. LÄS MER

3. 2. Streptococcus pneumoniae : epidemiological, clinical and serological studies

   Författare :Lars Å. Burman; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Streptococcus pneumoniae; incidence; predisposing factors; prognosis; serotyping; etiology of pneumonia; diagnostic methods; COA; CIE; pneumococcal serology;

   Sammanfattning : A retrospective study of invasive pneumococcal disease in patients from Greater Göteborg in 1964- 1980 identified 125 cases of meningitis, 305 of pneumonia, 61 of septicemia with unknown focus, and 17 with other manifestations, all verified by cultures from normally sterile body fluids. The incidence was several times higher in infants and in the elderly than in any other age-group. LÄS MER

   Sammanfattning : There are two main human pathogens in the family of Chlamydiaceae. Different serovars of Chlamydia trachomatis cause sexually-transmitted disease and eye infections whereas C. pneumoniae (TWAR) is a common cause of community-acquired respiratory infection. LÄS MER

5. 4. Apoptosis induced by a human milk protein complex. Cellular and structural studies in tumour cells and bacteria

   Författare :Anders Håkansson; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; serology; Immunology; nuclear uptake; caspases; mitochondria; S. pneumoniae; alpha-lactalbumin; milk; breast-feeding; Apoptosis; tumour cells; transplantation; Immunologi; serologi;

   Sammanfattning : Human milk contains a vast array of bioactive molecules, with nutritional and protective functions. This thesis describes the effects of a human milk protein complex, MAL, on tumour cells and bacteria. During our studies on the anti-adhesive properties of human milk we observed that a milk fraction killed tumour cells. LÄS MER

7. 5. Host responses to malaria and bacterial co-­infections

   Författare :Maria Nelson; Johan Normark; Sven Bergström; Anna Fahlgren; Olle Stendahl; Umeå universitet; []

   Sammanfattning : The two main causes of child mortality and morbidity in Africa are malaria and invasive bacterial diseases. In addition, co-infections in sub-Saharan Africa are the rule rather than the exception. However, not much is known about the host-pathogen interaction during a concomitant infection or how it affects the outcome of disease. LÄS MER
