用自昆明地区香石竹（Ｄｉａｎｔｈｏｕｓｃａｒｙｐｈｙｌｕｓ）植株上分离、提纯的香石竹斑驳病毒（ＣａｒＭＶ）为毒源，进行了腿肌肉、耳静脉、皮下和多方式多部位注射法等免疫家兔制备抗血清的比较实验．结果表明：多方式多部位注射免疫法得到的抗血清效价明显高于其它三种免疫方法所得的抗血清；获得的抗血清试管沉淀效价为１∶４０９６，琼脂糖双扩散效价可达１∶１０２４．将该抗血清用于５万余株香石竹的种苗、扦头的ＣａｒＭＶ检测中，结果如下：８１４２呈阳性结果，其中有６３９８株尚无病毒侵染症状（隐症）．这些隐症种苗隔离种植１２０ｄ后，５９０３株先后表现出病毒侵染症状，即抗血清对隐症带毒株检测的准确率达９２２６％．
