   Abstract : Listeria monocytogenes is a ubiquitous foodborne Gram-positive bacterium. Despite being mainly a soil bacterium, it can reach the food processing environment and contaminate food destined for human consumption, causing outbreaks. READ MORE

4. 2. Molecular mechanisms and immunomodulatory approaches in acute cystitis

   Author : Daniel Butler; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Urinary tract infection; acute cystitis; Immunomodulation; IL-1beta; hyper inflammatory disorder; neurokinins;

   Abstract : hand in the fight against resistant microbes. This thesis discusses the feasibility and potential of specific immunotherapy in treating acute bacterial infections and chronic sequels. The infection model is acute cystitis; the most common form of urinary tract infection, affecting millions of patients annually. READ MORE

5. 3. dNTPs : the alphabet of life

   Author : Dinesh Kumar; Andrei Chabes; Britt-Marie Sjöberg; Umeå universitet; []
   Keywords : ribonucleotide reductase; dNTP pools; s-phase checkpoint; mutagenesis; medicinsk biokemi; Medical Biochemistry;

   Abstract : From microscopic bacteria to the giant whale, every single living organism on Earth uses the same language of life: DNA. Deoxyribonucleoside triphosphates––dNTPs (dATP, dTTP, dGTP, and dCTP)––are the building blocks of DNA and are therefore the “alphabet of life”. READ MORE

6. 4. Interactions between Streptococcus pyogenes and the Human Immune System

   Author : Maria Weineisen; Lunds universitet; []

   Abstract : Streptococcus pyogenes is a common human pathogen causing mild infections such as tonsillitis and pharyngitis, but is also the cause of life-threatening conditions. To be able to infect the human host, S. pyogenes express different virulence factors. The surface-expressed M protein is a major virulence factor of S. READ MORE

7. 5. The significance of sexuality and cyst formation in the life-cycles of four marine dinoflagellate species

   Author : Rosa Figueroa; Enhet akvatisk ekologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cyst; Hydrobiology; akvatisk ekologi; marine biology; aquatic ecology; limnology; sexuality.; meiosis; Lingulodinium polyedrum; life-cyle; limnologi; Marinbiologi; Gymnodinium nolleri; Gymnodinium catenatum; Alexandrium catenella; dinoflagellates;

   Abstract : Sexuality and cyst formation were studied in the marine dinoflagellate species Gymnodinium catenatum Graham, Gymnodinium nolleri Ellegaard ? Moestrup, Alexandrium catenella (Whedon et Kofoid) Balech, and Lingulodinium polyedrum (Stein) Dodge. The study included the morphological characterization of sexual stages and processes, the time and description of meiosis, the study of the length and regulation of the mandatory dormancy period of resting cysts, and the relationships among parental strains and cyst progeny at phenotypic and molecular levels.
