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.

macroparasite

Infectious disease A parasite–eg, helminths, arthropods–which does not multiply in its definitive host, cycling instead through transmission stages–eggs and larvae–which pass into the external environment; immune responses evoked by macroparasites are transient and depend on the parasite load. Cf Microparasite.

Current theoretical and empiric work suggests that the outcome of coinfection can be different even for the same parasite system (e.g., [9]), depending on the level of resource competition between macro- and microparasites [4] or macroparasite burden and pathogenicity [2].
However, although malaria can behave sometimes as a microparasite and sometimes as a macroparasite [33], in the specific context of the proposed model, it can be considered as a microparasitic disease.
