Calicophoron daubneyi (Digenea: Paramphistomidae): The efficacy of anthelmintics in naturally infected cattle

Abstract

The effectiveness of anthelmintics in the treatment of paramphistomosis in farm animals in the Czech Republic has not been sufficiently investigated. This study was focused on selected breeds of beef cattle. Identification of Calicophoron daubneyi was performed by sedimentation and verified by PCR using the 5.8S rRNA gene. Animals were treated specifically for C. daubneyi infection only. Totally 400 positive animals were included in the study. The anthelmintic Closamectin (Closantel/Ivermectin) was evaluated as the most effective veterinary medicinal product with an efficiency of 80%, followed by Distocur (Oxyclozanid) with an efficiency of 78%, Aldifal (Albendazol) with an efficiency of 71% and Levatum Plus (Ivermectin/Clorsulon) with an efficiency of 62%.
