Anthelmintic Resistance in Farm and Companion Animals: A Review

Helminths are a class of worms that pose a serious threat to animal health all over the world. Parasite-caused infections reduce the productivity and well-being of livestock. The World Association for the Advancement of Veterinary Parasitology (WAAVP) raised awareness of this problem in 1992 by publishing techniques for identifying anthelmintic resistance. The most important factor influencing the rate at which AR develops is the frequency of treatment. Several management techniques, including pasture management and refugia, are used to try to prevent parasite infection and or maintain low infection pressure. These would lessen the need to use anthelmintics, which may help postpone the onset of AR. This review article included the development of AR in animals, detection of AR and the management of AR.
