Abstract
The detection, by means of faecal egg count reduction tests and larval cultures, of two cases of multiple anthelmintic resistance in goats and two in sheep, is reported. The former cases appeared to involve resistance to all three broad-spectrum drench groups (benzimidazole, levamisole, ivermectin) by mainly Ostertugia spp., the latter resistance to two of them (benzimidazole, levamisole) bv Trichostrondus spp. (New Zealand Veterinary Journal 38, 114–117, 1990)Keywords
