  abstract = {{A}lthough the term endemism refers to restricted areas of taxa, this term is used in a different way in epidemiology and host-parasite relationship. {A}n endemic disease refers to the maintenance of a disease over a long-term period in a limited geographic area (endemic area). {I}n biogeographical studies, endemism refers to the organisms that are restricted to a given area. {H}owever, little is known about parasitism in endemic hosts. {H}ere, we show how epidemiological models and the derivation of the basic transmission rate ({R}0) can help to understand the pattern of parasite species richness among endemic hosts. {T}he main prediction arising from epidemiological models concerns the host density threshold, i.e. the minimum host density that allows a disease to spread into a population of susceptible hosts. {W}hen host density, or host range, increases we can predict a concomitant increase of parasite species richness, in the case of parasites transmitted directly or through predator-prey relationship. {T}his prediction can be tested using comparative data. {T}hese predictions are successfully tested using several data sets on parasites of marine and freshwater fish. {W}e will show that restricted areas and/or low density is correlated with a decrease in parasite species richness. {T}he epidemiological theory is also helpful for predictions concerning parasite and disease introductions in endemic host faunas (or isolated hosts). {W}e emphasize why and how this endemic fauna may be susceptible to introduce pathogens and parasites.
