Novel compounds of the following formula: ##STR1## wherein R' is alkyl of 1 to 3 carbon atoms, X.sup.- is a nontoxic anion; b and c are positive numbers having values such that the positive charge of b moles of cation are neutralized by c moles of anion X.sup.- ; and -.sup.+ is a bicyclic heterocyclic base, of the group consisting of: ##STR2## wherein the dotted lines indicates that the methyl group can be present or a hydrogen group can be present, with the proviso that the two alpha methyl groups are not present at the same time, but that one alpha methyl group is required. These compounds have superior coccidiostatic activity.
以下化合物的新型化合物的公式:##STR1##其中R'是1至3个碳原子的烷基,X.sup.-是无毒的阴离子;b和c是正数,其值使b摩尔阳离子的正电荷被c摩尔阴离子X.sup.-中和;而-.sup.+是一种双环杂环碱基,属于以下组合之一:##STR2##其中虚线表示甲基基团可以存在或氢基团可以存在,但要求两个α-甲基基团不同时存在,但必须存在一个α-甲基基团。这些化合物具有优越的球虫抑制活性。
