  2. 16. Innate and acquired immunity to commensal bacteria

    Author : Christina Hessle; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The innate immune system recognises molecular patterns shared by large groups of micro-organisms. Monocytes and macrophages respond to microbes by production of substances which act in concert to promote effective clearance of bacteria. READ MORE

  4. 17. Food-Related Gram-Positive Bacteria: Enterotoxin A Expression in Staphylococcus aureus and a New Regulation Mechanism in Lactococcus lactis

    Author : Rong Cao; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lactococcus lactis; multiple inhibition kinetics; dehydrogenase; ATP; ADP; food factors; biopreservatives; staphylococcal food poisoning; SEA; prophage induction; enterotoxin A; Staphylococcus aureus;

    Abstract : Staphylococcal enterotoxin A (SEA) is the most common enterotoxin found in outbreaks of staphylococcal food poisoning (SFP). Based on the amount of SEA produced, S. aureus strains were divided into two main groups, high- and low-SEA-producing strains. READ MORE

  5. 18. Deoxyribonucleoside kinases in bacteria, plants and humans

    Author : Anders Ranegaard Clausen; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; anti-viral drugs; gene therapy; cancer; evolution; nucleoside analog; deoxyribonucleoside kinase; thymidine kinase;

    Abstract : Deoxyribonucleoside triphosphates (dNTPs) are the building blocks of DNA and can be synthesized either de novo or via salvage pathways. The first reaction in the salvage pathway of dNTPs is the conversion of deoxyribonucleosides (dN) into the deoxyribonucleoside monophosphate (dNMP). READ MORE

  6. 19. Staphylococcal surface display in directed evolution

    Author : Nina Kronqvist; Stefan Ståhl; Mats A. A. Persson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; affibody; combinatorial library; directed evoluation; Gram-positive bacteria. protein engineering; Bioengineering; Bioteknik;

    Abstract : Engineered affinity proteins have together with naturally derived antibodies becomeindispensable tools in many areas of life-science and with the increasing number ofapplications, the need for high-throughput methods for generation of such different affinityproteins is evident. Today, combinatorial protein engineering is the most successful strategy toisolate novel non-immunoglobulin affinity proteins. READ MORE

  7. 20. Assembly and adhesive properties of curli : a stationary phase-specific surface organelle in Gram-negative enteric bacteria

    Author : Mårten Hammar; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Escherichia colilcurli fimbriae csgstarvation;

    Abstract : The natural environments of bacteria are most often characterized by suboptimal conditions for growth, e. g., limited supply of nutrients. Consequently, periods of dormancy or negligible growth are the rule rather than the exception. READ MORE
