[Five past twelve - the resistance situation in small ruminant gastrointestinal nematodes in Germany]. / Fünf nach zwölf ­ zur Resistenzlage gastrointestinaler Nematoden bei kleinen Wiederkäuern in Deutschland.

ABSTRACT

Anthelmintic resistance has reached alarming levels worldwide and already seriously threatens pasture-based small ruminant production in certain geographic regions. The situation in Europe has also dramatically deteriorated in the last decade. This review provides an overview of the occurrence of anthelmintic resistance in small ruminants with a particular focus on Germany and its neighbouring countries. It also covers mechanisms leading to the development and spread of anthelmintic resistance, and recommendations for a responsible use of anthelmintics in veterinary practice.
