Treponemal antibodies are those that are:

a. produced against antigens of the organ-isms themselves.
b. produced by infected patients against components of mammalian cells.
c. produced by the organism that causes the systemic destruction of the disease.
d. also called reaginic antibodies.


A
Classic serologic tests for treponematosis measure the presence of two types of antibodies: tre-ponemal and nontreponemal. Treponemal antibodies are produced against antigens of the organ-isms themselves, whereas nontreponemal antibodies, often called reaginic antibodies, are pro-duced by infected patients against components of mammalian cells.
