Zusammenfassung

In Deutschland, Österreich und der Schweiz sind Resistenzen gegen Benzimidazole (BZ) bei kleinen Strongyliden des Pferdes und Trichostrongyliden (vor allem Haemonchus) des Schafes sehr weit verbreitet. Gelegentlich wurden bei Trichostrongyliden kleiner Wiederkäuer auch Mehrfachresistenzen gegen BZ, Levamisol oder makrozyklische Laktone (ML) festgestellt. Aus Großbritannien liegen Einzelberichte über ML-resistente Cooperia beim Rind vor. Triclabendazol- resistente Fasciola hepatica wurden in britischen und holländischen Schaf- und Rinderherden nachgewiesen. In der vorliegenden Arbeit werden Grundlagen der Resistenzentwicklung erläutert und für jede Wirtstierart praktikable Maßnahmen vorgestellt, durch die eine weitere Resistenzentwicklung verzögert werden kann.

Summary

Benzimidazole (BZ) resistance is highly prevalent in cyathostomin populations of horses and trichostrongyle populations (mainly Haemonchus) of sheep in Germany, Austria and Switzerland. Multiple resistance against BZ, levamisole or macrocyclic lactones (ML) was found in few sheep or goat farms of these countries. A few cases of ML resistance in Cooperia were reported from dairy cattle farms in Great Britain. Resistance of Fasciola hepatica against triclabendazole was recently detected in The Netherlands and Great Britain. This paper reviews key points of the development of resistance and presents, for each host species, measures to prevent or delay the further development of resistance.
