  2. 11. 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

  4. 12. Surface proteins of Finegoldia magna interacting with the human host

    Author : Christofer Karlsson; Infektionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Finegoldia magna; Gram-positive anaerobic cocci; surface proteins; protease; LL-37; MIG CXCL9; Fibrinogen; adhesion; gene disruption; bacterial aggregation; basement membranes;

    Abstract : Finegoldia magna is a Gram-positive anaerobe and a member of the normal human microflora. This bacterium is also an opportunistic pathogen and isolated from ~10% of all anaerobic infections. Reoccurring taxonomical changes and the anaerobic growth have contributed to the neglect of F. magna. READ MORE

  5. 13. 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

  6. 14. 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

  7. 15. Studies on cell wall-attached proteins of Streptococcus pyogenes

    Author : Magnus Rasmussen; Infektionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; insertion sequence; phase variation; collagen-like; alpha2-macroglobulin; pattern; virulence; surface protein; Stretococcus pyogenes; cell wall-attached protein; Clinical biology; Klinisk biologi;

    Abstract : Cell wall-attached proteins (CWPs) are important for the virulence of Gram-positive bacteria, but are also targets for the host immune system. CWPs have a conserved COOH-terminal region, responsible for cell wall-sorting. A pattern based on this conserved region was developed. READ MORE
