摘　　要：根据羊结肠小袋纤毛虫滋养体消毒剂杀灭试验的绝对致死浓度(lethal concentration,LC100),筛选高锰酸钾、福尔马林和NaOH进行半数致死浓度(LC50)测定试验。结果表明,高锰酸钾、福尔马林和NaOH对羊结肠小袋纤毛虫2 h的半数致死浓度(LC50)分别为8.531×10-4、4.213×10-4和10.50×10-4,12 h的半数致死浓度(LC50)分别为6.502×10^(-5)、8.267×10^(-5)和10.31×10^(-5)。三种药物均是体外杀灭羊结肠小袋纤毛虫滋养体的高效消毒剂。Potassium permanganate,formalin and NaOH were selected to determine their median lethal concentration(LC50)based on the absolute lethal concentration(LC100)of these disinfectants to kill trophozoites of sheep balantidium coli.The results showed that LC50 doses of potassium permanganate,formalin and NaOH to kill trophozoites of sheep balantidium coli were 8.531×10-4,4.213×10-4 and 10.50×10-4 within 2 hours and 6.502×10-5,8.267×10-5 and 10.31×10-5 within 12 hours,respectively.Therefore,these three disinfectants can effectively kill trophozoites of sheep balantidium coli.
