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.
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%.
The case highlights the need to review current worm control strategies, especially for young horses.
在过去十年中，已有几篇关于大环内酯类（ML）耐药性马副蛔虫的国际报告，但澳大利亚马副蛔虫种群的耐药状况在很大程度上尚不清楚。对澳大利亚一例伊维菌素对马副蛔虫疗效明显降低的病例进行了调查。
对昆士兰州东南部一组断奶幼驹进行的粪便虫卵计数减少试验表明，伊维菌素的疗效为65%。
该病例凸显了审查当前蠕虫控制策略的必要性，特别是对于幼驹而言。
