Abstract
Duchaaek L., J. Lamka: Dicrocoeliosis ‐ the Present State of Knowledge with Respect to Wildlife Species. Acta Vet. Brno 2003, 72: 613-626. The present paper summarizes contemporary knowledge concerning dicrocoeliosis (chronic disease of the liver caused by the lancet fluke Dicrocoelium dendriticum) as to its spraed, etiology, life cycle, epidemiology, pathogenesis, immunogenesis, clinical symptoms, diagnostics, therapy, prevention of dicrocoeliosis, and human infection. The major part of published data is connected with farm animal husbandry, dicrocoeliosis of wildlife species is examined to a limited extent only. Although dicrocoeliosis is intensively studied, numerous aspects of this trematodosis have to be verified. Control of dicrocoeliosis in domesticated and wildlife species is not fully effective at present. Dicrocoelium dendriticum, lancet fluke Dicrocoeliosis is a helmithosis caused by the lancet fluke Dicrocoelium dendriticum Rudolphi, 1819 (D. dendriticum, syn. D. lanceolatum, Dicrocoelidae, Platyhelminthes), parasitizing in the liver of ruminants as well as many other animals species including man. This parasitosis belongs to the six principal and economically most important pasture helminthoses of sheep and cattle‐trichostrongylidosis, dictyocaulosis, protostrongylidosis, moniesiosis, fasciolosis, and dicrocoeliosis (Hiepe 1994). Parasitosis accompanies man and farm animals breeding from time immemorial. The eggs of D. dendriticum were found in the coprolites and paleofaeces of the prehistoric human population in Central Europe. Nevertheless, it is not certain whether the lancet fluke D. dendriticum was a real parasite, or whether the found eggs indicate pseudoparasitism after consummation of animal liver (Aspock et al. 1999).
