Eggs and rhabditiform juveniles of the ruminant parasite Trichostrongylus colubriformis developed normally in Caenorhabditis briggsae Maintenance Medium. A toxin from a crystal-enriched preparation of the bacterium Bacillus thuringiensis israelensis was lethal to nematode eggs and juveniles within 24 hours and to eggs and juveniles after 24 hours of development. Treated eggs had refractive granules and development was arrested, whereas nontreated eggs developed normally. Eggs treated after 24 hours of development contained juveniles that were granulated, had esophageal derangements, and were moribund or dead. The ovicidal toxin from B. t. israelensis may facilitate microbial control of parasitic nematodes.
反刍动物寄生虫蛇形毛圆线虫的虫卵和杆状蚴在秀丽隐杆线虫维持培养基中正常发育。来自苏云金芽孢杆菌以色列亚种晶体富集制剂的一种毒素在24小时内对线虫卵和幼虫具有致死性,对发育24小时后的虫卵和幼虫也有致死性。经处理的虫卵有折光性颗粒,发育停滞,而未处理的虫卵正常发育。发育24小时后处理的虫卵内的幼虫有颗粒,食管紊乱,濒死或死亡。苏云金芽孢杆菌以色列亚种的杀卵毒素可能有助于对寄生线虫进行微生物控制。
