Adaptive Immunity: Specific Defenses of the Host |
||||
Antibody titre - the concentration of antibody in serum
Primary response - response to first contact with antigen; characterized by the appearance of IgM, followed by IgG.
Secondary (anamnestic or memory) response - subsequent contact with the same antigen by memory cells results in a much stronger and faster response - antibody titre is much higher, occurs much faster, and consists primarily of IgG.
Acquired immunity is specific resistance to infection developed during the life of the individual
Antiserum: serum containing antibodies. Antibodies are proteins, so they may be referred to as globulins, and are often referred to as immunoglobulins.
