Abstract

Faecal egg count reduction test (FECRT) and in vitro egg hatch assay (EHA) was performed on Indian Karakul (3/4 crosses of Karakul with Malpura, Marwari and Sonadi) transported from arid region campus, Bikaner, where resistance was reported in 1996. FECRT revealed that fenbendazole and levamisole were 100% effective in reducing the egg counts. LC50 value on EHA was 0.074 +/- 0.015 microg thiabendazole ml(-1). The faecal culture examination revealed the presence of Haemonchus contortus only. It was concluded that H. contortus was fully susceptible to both benzimidazole and levamisole.

摘要

对从比卡内尔干旱地区校区运来的印度卡拉库尔羊（卡拉库尔羊与马尔普拉羊、马尔瓦里羊和索纳迪羊的3/4杂交品种）进行了粪便虫卵计数减少试验（FECRT）和体外虫卵孵化试验（EHA），该地区在1996年曾报告有抗药性。FECRT显示，芬苯达唑和左旋咪唑在减少虫卵计数方面的有效性为100%。EHA的LC50值为0.074±0.015微克噻苯达唑/毫升。粪便培养检查仅发现有捻转血矛线虫。得出的结论是，捻转血矛线虫对苯并咪唑类和左旋咪唑均完全敏感。
