A cross-sectional field study on the prevalence of Dicrocoelium dendriticum was performed in the Emmental. The study included 211 bovines, 170 equines, 20 ovines, 46 caprines and 23 rabbits (from 119 farms). In addition, laboratory routine diagnostic data obtained from 2.840 animals--all originating from the same area of investigation--were assessed in the same way. The infection extent concerning the different animal species were the following: bovines 46%, equines 12%, ovines 30%, caprines 48% and rabbits 9%. Univariate analyses of baseline epidemiological data identified no significant risk factors, with the exception of the type of stable used. Bovines kept in a modern free ranging stable had a significantly lower chance of infection with D. dendriticum than cattle in conventional tie stalls. The epidemiological data characterizing the area of investigation suggest the following procedure to reduce the problem of dicrocoeliosis: Pasturing animals of all ages should be regularly dewormed (e.g. every six week during pasture) using a compound effective against D. dendriticum. A treatment is especially indicated at the time after pasture in autumn or before housing the animals in winter. In spring, only animals having pastured the year before need to be treated prior to pasture in the new year. However, it is recommended to perform an economic analysis comparing costs of treatment versus putative costs of damage prior to the initiation of a strategic campaign: animal welfare aspects have to be considered. The laboratory routine diagnostic data showed infection extent similar to those of the cross-sectional study: bovines 60%, equines 24%, ovines 26%, caprines 31%, rabbits 32%. Atypical hosts such as dogs and cats exhibited low infection extent (3% and 1%, respectively), rather reflecting a gastro-intestinal passage of parasite eggs ingested by consumption of infected livers or by coprophagy of ruminant faeces.
