macroparasite

Those parasites (e.g., helminths, arthropods) that do not multiply within their definitive host, cycling instead through transmission stages (eggs and larvae), which pass to the outside. Immune responses evoked by macroparasites are transient and depend on the parasite load; the key epidemiologic measure is the number of parasites per host.
