Name
Latin: capillus = hair of head; philippinensis =belongs to the Philippines. English: capillary.
Geographic Distribution/Epidemiology
Worldwide occurrence in different densities; epidemics in crowded farms or in rural regions.
Morphology/Life Cycles
There are several species, which use different animals as final hosts (see Capillaria species of animals); however, some of them (e.g., Capillaria aerophila, C. hepatica (syn. Calodium hepaticum) or C. philippinensis) parasitize also in humans (Fig. 1). The adults live in species-specific organs (C. philippinensis in the small intestine; C. hepatica in liver). Adults of C. hepatica are long (♀ = 8–10 cm, ♂ = 3 cm), while those of C. philippinensis are tiny (♀ = 3 cm, ♂ = 3 mm). The larva 1 develops inside excreted eggs within 1–2 weeks. These larvae 1 may be ingested directly by the final hosts or by an earthworm (e.g., C. aerophila), wherein the larva 3 develops as it occurs in the eggs of the other species. In the case of C....
