Albendazole (ABZ) has been used for control of ovine fasciolosis in Sweden for several decades. However, increasing prevalence of Fasciola hepatica in Sweden requires attention to diagnostic tools and current control strategies. The coproantigen reduction test (CRT) using commercial Bio-X K201 Fasciola coproantigen ELISA (Bio-X Diagnostics, Jemelle, Belgium) was recently suggested as a novel method for diagnosis of patent F. hepatica infection. The aim of this study was to compare the efficacy of albendazole and triclabendazole (TCBZ) treatment against F. hepatica in naturally infected sheep in south-western Sweden by CRT, and also to evaluate the usefulness of this test as a diagnostic marker for anthelmintic efficacy following treatment with ABZ. Three weeks after housing, 24 serologically positive ewes on a commercial farm in Sweden were randomly allocated into three groups, which were either dewormed with 5 mg/kg ABZ, 10 mg/ml TCBZ or left untreated. Twenty-six days after initial administration of these anthelmintics, all of the sheep in the ABZ group and untreated control groups were treated with 10 mg/kg TCBZ. While TCBZ caused elimination of coproantigen and eggs in faeces 7 days after application, ABZ treatment failed completely. Neither anthelmintic resistance, underdosing, nor lack of efficacy due to the presence of immature flukes can be out ruled as possible causes. Despite some deviations in conformity between coproantigen levels and presence of fluke eggs, the CRT was a useful tool for measuring treatment efficacies. (C) 2012 Elsevier B.V. All rights reserved.
