The most effective antibody type against parasites is IgE. This antibody plays a crucial role in the immune response to larger pathogens, particularly helminths (parasitic worms) and protozoa. When an individual is exposed to a parasitic infection, IgE is produced and binds to the surface of the parasites as well as to receptors on immune cells, such as mast cells and basophils. This binding triggers the release of various mediators, including histamines and cytokines, which are instrumental in combating the parasites.

Additionally, IgE is associated with allergic reactions, which can also be a response to certain parasites. The presence of IgE can enhance the activity of immune cells, facilitating the destruction of the parasites through mechanisms like degranulation of mast cells, which releases toxic substances that are harmful to the parasites.

In contrast, other antibody types have different primary functions. For example, IgG is the most abundant antibody and is primarily involved in responses to bacteria and viruses. IgD's role remains less understood, primarily acting as a receptor on B cells. IgM is often the first antibody produced in response to an infection but is not specifically tailored to combat parasites like IgE.

Thus, in the context of targeting and neutralizing
