22 Questions
What is the primary immune response?
The response when an antigen enters the body for the first time
Which specific exotoxins does humoral immunity directly target?
Tetanus and diphtheria
What antibody is the first to be presented when exposed to infection for the first time?
IgM; followed by IgG or IgA
What type of pathogens are more important for protection against in cell-mediated immunity?
Intracellular
What specific virulence does humoral immunity direct against?
Pneumococci, meningococci, haemophilus influenzae
How many days is the lag period before antibodies become detectable in the serum?
7-10 days
During the secondary response, which antibody will be in higher concentration?
IgG
What is the duration of the antibody response in the secondary response?
Long
What is the primary function of antibodies?
Neutralize toxins and viruses
How does the host cell react when two or more antigens are administered at the same time?
By producing antibodies to all of them
What are the two main functions of antibodies?
Opsonize microorganisms and promote inflammation
What is opsonization?
When antibodies facilitate microorganism ingestion by phagocytic cells
What are the processes done for the evaluation of humoral immunity?
Measuring amounts of IgG, IgM, and IgA
What are the tests used for the evaluation of humoral immunity?
Nephelometry and Immuno-electrophoresis
