1. Foodborne Virulence: Staphylococcus aureus Enterotoxins A and D
Abstract : The development of new, minimally processed food products challenges traditional concepts of food safety. How pathogenic bacteria behave in these new matrices is not known. To fill this knowledge gap and enable the production of food that is safe for the consumer, more information on virulence expression of pathogens in food matrices is required. READ MORE

2. Staphylococcus aureus toxins - Influence on food safety and animal health
Abstract : 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). READ MORE

3. Staphylococcal enterotoxin H - structure and function of a superantigen
Abstract : The aim of this thesis was to characterise the biological functions of the superantigen staphylococcal enterotoxin H (SEH). Superantigens are highly immunostimulatory proteins, which crosslink T cells and antigen presenting cells (APCs). READ MORE

4. Structural studies of metal-binding proteins revealing dynamic behaviour
Abstract : The Mg2+ and Mn2+ structures of calbindin D9k have been determined and they reveal a conformational change compared to the structures of apo and (Ca2+)2-calbindin D9k. These findings are unique, since normally calcium and not magnesium is known to induce conformational changes of EF-hand proteins. READ MORE

5. The immunomodulatory function of staphylococcal superantigen on oral tolerance
Abstract : Exposure to soluble proteins via the gut gives rise to systemic tolerance, a phenomenon called oral tolerance. Failure of oral tolerance results in allergy, a disease that has increased during the last decades in Western industrialized countries. The cause of this rapid increase is unknown. READ MORE
