Immunity may be innate or acquired. Which of the following best describes acquired immunity?
|B||Increase in C-reactive protein|
|D||Maternal transfer of antibody|
Natural immunity is nonspecific. The natural immune functions described are not specific for a certain antigen. For example, certain proteins such as C-reactive protein (CRP) are acute-phase reactants.
While elevated CRP is seen in infection, it is not disease-specific.
Maternal transfer of antibody, however, is passive but still confers specific immunity It is termed acquired immunity
