What is a pathogen? ~~> A microorganism that causes disease e.g. bacteria, fungi, virus, parasite For an effective immune response the immune system must... ~~> - be able to recognise and respond to any invading organism - not over react to benign or self - be able to direct different effector mechanisms against different pathogens What is specific/adaptive immunity? ~~> - it is induced by exposure to a particular infection - shows a high degree of specificity - exhib...

What is the hapten-carrier effect? correct answer: Small-molecule antigen requires covalent linkage to a larger carrier to stimulate adaptive immune response. The process is achieved in collaboration between hapten-specific B cells and carrier-specific T cells. This is the basis of developing conjugated vaccines. What are the common superantigens and related diseases? correct answer: SEB and SEC from Staphylococcus aureus cause food poisoning. TSST from Staphylococcus aureus and SPE-C from ...
