在实验室条件下,分离培养鲤斜管虫和指状拟舟虫并进行体外杀灭试验,通过细胞计数及目测法比较6种中草药的抗原虫效果。结果表明:这6种中草药对指状拟舟虫的杀灭效果总体要好于鲤斜管虫,其中,苦楝和苦参的效果最好。结合这6种中草药的安全浓度可以得出结论:苦楝和苦参适合用于防治鱼类的这两类纤毛虫病。 Under laboratory conditions, carp tube beetles and finger carnivores were isolated and cultured, and the killing test was conducted in vitro. The anti-protozoal effects of six Chinese herbal medicines were compared by cell counting and visual inspection. The results showed that the killing effect of these six kinds of Chinese herbs on the finger-shaped carnivores was better than that of the common carp. Among them, the effect of Melia azedarach and Sophora flavescens was the best. Combined with the safe concentration of these six herbs can be concluded: Neem and sophora flavescens suitable for the prevention and treatment of these two types of ciliates fish disease.
