本文目的在于观察用吡喳酮治愈对牛血吸虫具有自然获得性抵抗力的牛的可能性。实验共用自然感染牛血吸虫5～8年的牛12头。这些牛经抗血吸虫病治疗后,在3周内作粪内血吸虫虫卵计数5次,其中半数牛用吡喹酮25mg/kg治疗两次,间隔期为3周,于第2次治疗后7周,与另外来自非流行区的同龄的6头牛同时感染,每头牛在2周半内经皮攻击感染1～3次,接种牛血吸虫尾蚴共为70,000条。于攻击感染后16～18
The purpose of this paper is to look at the possibility of using ciclopirox to cure cattle with naturally acquired resistance to bovine schistosomes. Experiments shared natural infected cattle Schistosome 5 to 8 years 12 cattle. After being treated with anti-schistosomiasis, these bovine eggs were counted 5 times for schistosome within 3 weeks, half of which were treated with praziquantel 25 mg / kg twice a day for 3 weeks. After the second treatment 7 Week and 6 cow of the same age from other than non-endemic areas. Each cow infected 1 to 3 times by percutaneous attack within 2 weeks and half, with a total of 70,000 inoculated cercariae of Schistosoma japonicum. After the attack infection 16 ~ 18
