Final answer:
IgE-type antibodies are associated with the body's defense against parasites and are also known to play a role in allergic responses.
Step-by-step explanation:
The antibodies associated with body defenses against parasites are IgE-type antibodies. IgE is involved in the defense against parasitic infections and plays a role in allergic responses. Unlike IgM antibodies, which are released early and form pentamers, IgE antibodies are involved in different immune responses, particularly those against parasitic infestations and allergic reactions. Furthermore, IgG is another important antibody that can cross the placenta and protect the developing fetus, but it is more typically associated with secondary immune responses rather than parasite defense.
