Suspected ivermectin resistance in a south-east Queensland parascaris equorum population

Beasley, A. and Coleman, G. and Kotze, A. C. (2015) Suspected ivermectin resistance in a south-east Queensland parascaris equorum population. Australian Veterinary Journal, 93 (9). pp. 305-307. ISSN 0005-0423


Background: There have been several international reports of macrocyclic lactone (ML)-resistant Parascaris equorum over the past decade, but the resistance status of Australian P. equorum populations is largely unknown. A case of apparent reduced efficacy of ivermectin against P. equorum in Australia was investigated. Methods and Results: A faecal egg count reduction test carried out on a group of weanling foals in south-east Queensland showed the efficacy of ivermectin to be 65%. Conclusion: The case highlights the need to review current worm control strategies, especially for young horses.
