1. Describe active versus passive immunity and provide an example of each. Define antibody or immunoglobulin and describe the five molecular classes of immunoglobulins and their function(s) in the body by providing a pathologic example for an increase of each immunoglobulin (e.g., IgE—parasitic infection). Why are some viruses inaccessible to antibodies after initial infection?
