چکیده
Published Online First November 6, 2013 identification of coprocultures at day 0 showed that all larvae in the control group were H contortus. In the MOX, DRM, MPL, FBZ and LEV/TCBZ groups, H contortus made up 97 per cent, 95 per cent, 94 per cent, 97 per cent and 98 per cent of the larvae, respectively. Larval identification of coprocultures after treatment with MOX, DRM and FBZ revealed 99 per cent, 100 per cent and 98 per cent H contortus larvae, respectively. In the LEV/TCBZ group, only five larvae were detected. No larvae were detected in the MPL group.

Changes in anthelmintic resistance over the past 16 years is documented following the isolation of a field strain of Haemonchus contortus in sheep showing multiple anthelmintic resistance at Lawes in south eastern Queensland in 1979. Resistance to thiabendazole was first suspected in 1969 and continued to persist until the present time. In addition resistance to fenbendazole and oxfendazole als...
