Anthelmintic Resistance in Livestock

Abstract

For decades anthelmintics have been used as the primary control measure for worm infections in livestock. However, there has been continuous development of anthelmintic resistance (AR) by the parasitic worms infecting livestock. This chapter reviews AR in livestock with a special focus on treatment and control, modes of action of different anthelmintic classes, risk factors leading to development of AR, conventional and molecular tools used to detect AR, FAMACHA© and holistic control strategy to control anthelmintic resistance.
