摘　　要：用口服患病克氏原螯虾(Procamgbarus clarkii)组织、注射拟态弧菌(Vibrio mimicus)和副溶血弧菌(Vibrio parahaemolyticus)的方法,人工感染健康克氏原螯虾致病后,定时投喂盐酸土霉素药物饵料,观察了药物饵料对人工致病克氏原螯虾的治疗效果。结果表明,投喂含有盐酸土霉素的药物饵料对人工注射V.mimicus和V.parahaemolyticus致病的克氏原螯虾有比较好的治疗效果,而对口服患病克氏原螯虾组织致病的克氏原螯虾的治疗效果比较差。但是,与口服患病克氏原螯虾组织致病后未用药物饵料治疗的对照组相比,投喂药物饵料对克氏原螯虾疾病发展有一定的控制作用。推测克氏原螯虾暴发性疾病的致病原因主要是由于致病病毒引起,而致病菌在克氏原螯虾体内的存在,可能导致混合感染而死亡率上升。Healthy red swamp crayfish,Procamgbarus clarkii were artificially infected by feeding on tissues of diseased red swamp crayfish or injection of Vibrio mirnicus and Vibrio parahaernolyticus. Infected red swamp crayfish were fed with feed supplemented with oxytetracycline hydrochloride on a fixed schedule and the treatment effects were studied. Results showed that feed supplemented with oxytetracycline hydrochloride had a satisfying effect on diseased red swamp crayfish injected with Vibrio mimicus and Vibrio parahaernolyticus ,while had a poor effect on red swamp crayfish fed on tissues from diseased red swamp crayfish. But compared to those artificially infected red swamp crayfish fed without oxytetracycline hydrochloride,the feed supplemented with oxytetracycline hydrochloride did have some controlling effect. It was speculated that the pathogenic organisms of explosive epidemic in red swamp crayfish might be a combination of pathogenic virus and bacteria.
