The prevalence and level of thiabendazole resistance of sheep nematodes in the North Island of New Zealand was investigated by means of an in vitro egg-hatch technique; samples from sheep on 52 properties in six country areas were examined. Resistance of Haemonchus contortus and Trichostrongylus spp. was identified on the basis of egg hatch in 0.1 ppm thiabendazole. Evidence of resistance was obtained on 11(21.2%) of the properties. LD 50's and resistance ratios were calculated for the resistant nematode populations found.
采用体外虫卵孵化技术对新西兰北岛绵羊体内线虫的噻苯达唑耐药性流行情况和水平进行了调查;对六个乡村地区52个牧场绵羊的样本进行了检测。基于在0.1 ppm噻苯达唑中的虫卵孵化情况确定了捻转血矛线虫和毛圆线虫属的耐药性。在11个(21.2%)牧场获得了耐药证据。对发现的耐药线虫种群计算了半数致死剂量(LD50)和耐药比。
