[Biodiversity of Capillariinae].

The subfamily Capillariinae includes about 300 species of nematodes parasitizing all groups of vertebrates. Taxonomy and systematics of this parasites have been changed many times because of a difficulty in designation of particular species' features. That's why there are a lot of synonyms in this group. Nowadays most authors accept the systematics, of Capillariinae according to Moravec. Biology and ecology of species parasitizing breeding birds and mammals is well known, however data relative to capillaria of wild animals are fragmentary. Capillariinae parasitize in various part of alimentary system: mainly in intestine, stomach, duodenum, rarely in oesophagus, rectum or bursa of Fabricius and liver as well as respiratory and excretory systems. Pathogenicity depends on localization of nematodes and the age of the hosts, and on infection intensity. Species recorded in human beings are: Aonchotheca philippinensis, Eucoleus aerophilus and Calodium hepaticum. They are a cause of intestinal, lung and hepatic capillariosis.
