With the objective of studying the role of wild fauna in the epidemiology of fasciolosis disease, a definitive wild-host inventory was carried out in a french form where infected domestic hosts (cows) cohabit with wild potential ones, liver flukes, faecal eggs and antibodies were looked for in lagomorphs (Oryctologus cuniculus) and rodents (Myocastor coypus, Ondotra zybethicus, Rattus norvegicus, Arvicola sapidus and micromammal species) trapped in the study area. Presence of Fasciola hepatica was detected in two species: O. cuniculus and M. coypus. infection rates were respectively 34 % (42/124) and 55 % (106/193), liver flukes were found in 78 M. coypus (n = 192) and 11 O. cuniculus (n = 35). No other species was infected by F. hepatica. The number of animals shedding fluke eggs was higher in M. coypus (49 out of 127 sampled; 38.6 %) than in O. cuniculus (two out of 17 sampled; 11.7 %). The results indicate that M. coypus may ploy a role in the maintenance and the dissemination of F. hepatica in various environments and open a discussion on the role of other natural wild hosts.
