Abstract:

The resistance of Haemonchus contortus to anthelmintics such as ivermectin and albendazole has become increasingly serious, causing major losses to the aquaculture industry in most countries and regions of the world. Currently, research on drug resistance in Haemonchus contortus focuses on epidemiological studies, drug resistance mechanisms and drug resistance interventions, and has made some progress. In this paper, we review the distribution of drug resistance and its influencing factors, the mechanism of drug resistance and reversal of drug resistance based on cell membrane pumps, autophagy level, cellular respiratory chain, parasite substitution, combined deworming with plant extracts and anthelmintics, and breeding of resistant hosts, to provide a new way of thinking for the study of drug resistance in Haemonchus contortus, and to provide reference bases for the scientific control of Haemonchus contortus, the rational use of drugs, and the development of new drugs. It also provides a reference base for scientific control, rational use of drugs and development of new drugs.

Key words: Haemonchus contortus, drug resistance distribution, drug resistance mechanism, reversal of drug resistance
