  1. 41. Regulation of Plasmodium falciparum virulence genes and immune response to surface antigens in placental malaria

    Författare :Kim Brolin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Malaria infection caused by the parasite Plasmodium falciparum is a deadly torment, especially for young children and pregnant women residing in sub-Saharan Africa. Much of the parasites virulence is due to its ability to constantly vary the adhesive molecules expressed on the surface of infected red blood cells (iRBCs). LÄS MER

  3. 42. Detailed structural studies towards the understanding of lipopolysaccharide glycan expression in non-typeable Haemophilus influenzae

    Författare :Susanna Lundström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Haemophilus influenzae (Hi) is a host-adapted Gram-negative bacterium that regularly colonizes the respiratory tract of humans. Hi is an important cause of disease worldwide and exists in encapsulated and unencapsulated (non-typeable, NT) forms. LÄS MER

    Sammanfattning : Hospital acquired (i.e. nosocomial) infections and antibiotic resistance are large issues in the world today, with about 1.3 million people estimated to have died from antibiotic resistant infections in 2019 alone, and these problems are on the rise. LÄS MER

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

    Författare :Rong Cao; Teknisk mikrobiologi; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 45. Staphylococcus aureus toxins - Influence on food safety and animal health

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Staphylococcus aureus; toxins; food safety; enterotoxin A SEA ; prophage life cycle; GFP reporter strain; flow cytometry; enterotoxin D SED ; accessory gene regulator agr ; bovine mastitis; enterotoxin C SEC ; toxic shock syndrome toxin-1 TSST-1 ;

    Sammanfattning : Staphylococcus aureus (S. aureus) is a notorious opportunistic foodborne pathogen and also a common cause of bovine mastitis. It is known to produce many different virulence factors, including various staphylococcal enterotoxins and toxic shock syndrome toxin-1 (TSST-1). LÄS MER
