Ichthyophthiriasis, which is caused by Ichthyophthirius multifiliis (Ich) infections, has a severe impact on productivity in freshwater aquaculture. These infections were previously treated effectively with malachite green, a compound that is now banned on fish farms due to its carcinogenicity. To find efficacious drugs to control Ich, flowers of tansy Tanacetum vulgare were evaluated for their antiprotozoal activity. Tanacetum vulgare extract significantly reduced the survival of Ich trophonts and theronts. In vitro, the extract killed all trophonts at 3200 mg l-1, terminated tomont reproduction at 50 mg l-1, and caused mortality of all theronts at 100 mg l-1. T. vulgare extract may be a new and efficacious drug for the control of Ich.
粘孢子虫病由多子小瓜虫（Ich）感染引起，对淡水水产养殖的生产力有严重影响。这些感染以前可以用孔雀石绿有效地治疗，由于其致癌性，现在已禁止在鱼场使用。为了寻找有效的药物来控制粘孢子虫病，评估了苦艾菊（Tanacetum vulgare）的花的抗原生动物活性。苦艾菊提取物显著降低了粘孢子虫滋养体和包囊的存活率。在体外，提取物在 3200mg l-1 时杀死所有滋养体，在 50mg l-1 时终止包囊繁殖，在 100mg l-1 时导致所有包囊死亡。苦艾菊提取物可能是控制粘孢子虫病的一种新的有效药物。
