Related to microparasite: Macroparasite

burgdorferi were host specialized, the strains of this microparasite would migrate differentially, resulting in geographic structuring of this pathogen.
burgdorferi can be confidently compared with that of other microparasites.
Despite this, microparasites (generally prions, viruses, bacteria, fungi, and protozoans) often remain the singular focus of research on emerging infectious diseases (35,36).
Past researchers have used macroparasites as a measurement of an organism's fitness level without taking into account that they might be benign to the host's fitness, as well as unintentionally ignoring the effects of the microparasites that may also simultaneously inhabit the host.
McNeill (1992) has aptly termed microparasites and macroparasites.
At the same time, however, settled populations became increasingly vulnerable to both microparasites and macroparasites.

Ability to infect a range of host species is a characteristic of many invading pathogens (10) and is less common in endemic microparasites that have coevolved with their hosts.
Microparasites such as Batrachochytrium, with their relatively short duration of infection and high death rates, have an increased threshold population density and are usually less able to persist.
