使用粪便卵数减少试验 (FECRT) 对主要来自苏格兰南部/中部的 38 只羊群进行了检查，以确定是否存在伊维菌素 (IVM) 抗性线虫。有效率低于95%。处理后 14-17 天，在 17 个自然放牧的鸡群中，有 6 个鸡群在处理前粪便中虫卵数量超过每克 150 个虫卵。这些 IVM 抗性农场的效率在 66% 至 92% 之间。在退回的材料中还发现了另外一例疑似 IVM 耐药病例。在处理后共生培养中从抗性鸡群中检测到的幼虫来自 Teladorsagia 属（6 只中的 4 只）和毛圆线虫属（6 只中的 2 只）。 (C) 2005 Elsevier B.V. 保留所有权利。
Thirty-eight sheep flocks, predominantly from the south/central Scotland, were examined using a faecal egg count reduction test (FECRT) for the presence of ivermectin (IVM) resistant nematodes. Efficacies of less than 95%. 14-17 days post-treatment, were identified in 6 of 17 naturally grazing flocks where pre-treatment faecal egg counts were in excess of 150 eggs per gram. Efficacies on these IVM resistant farms ranged from 66 to 92%. One other suspected cases of IVM resistance was also identified in returned material. The larvae detected in post-treatment coprocultures from resistant flocks were from the genera Teladorsagia (4 from 6) and Trichostrongylus (2 from 6). (C) 2005 Elsevier B.V. All rights reserved.
