通过两个试验来测试不同治疗剂对日光鲈鱼的气单胞菌和柱状黄杆菌混合感染的有效性。实验1评价了硫酸铜、氟苯尼考加药饲料和高锰酸钾（KMnO 4）对自然混合感染的作用。实验2进一步评估了硫酸铜作为控制实验性混合感染的治疗。在实验1中，自然感染的未经处理的鱼有最低的最终存活率，在71%，而氟苯尼考药物饲料在15毫克公斤-1体重为10天或硫酸铜在2.1毫克L-1（总碱度的1%）为24小时产生最高的最终存活率，在90%和88%，分别。自然感染的鱼投喂氟苯尼考药物饲料的最终存活率与未处理的鱼有显著差异（P < 0.1）。氟苯尼考和硫酸铜在2.1毫克L-1的生存曲线显着改善未经处理的鱼。在实验2中，鱼的挑战，通过水暴露于A. pagoda和F.columnare，无论是不处理或处理硫酸铜在2.1毫克L-1。在实验2结束时，用硫酸铜处理的受攻击鱼的存活百分比（99%）显著高于未处理的（61%）（P < 0.05）。结果表明，氟苯尼考和硫酸铜对A. rectica和F. columnare的混合感染有明显的益处。
Two experiments were conducted to test the effectiveness of different therapeutants against a mixed infection of Aeromonas hydrophila and Flavobacterium columnare in sunshine bass. Experiment 1 evaluated copper sulphate, florfenicol-medicated feed and potassium permanganate (KMnO4) against a natural mixed infection. Experiment 2 further evaluated copper sulphate as a treatment to control an experimental mixed infection. In experiment 1, naturally infected untreated fish had the lowest final survival per cent, at 71%, while florfenicol-medicated feed at 15 mg kg-1 body weight for 10 days or copper sulphate at 2.1 mg L-1 (1% of the total alkalinity) for 24 h produced the highest final survivals, at 90% and 88%, respectively. The final survival of the naturally infected fish administered florfenicol-medicated feed was significantly different (P < 0.1) from the untreated fish. The survival curves for the florfenicol and the copper sulphate at 2.1 mg L-1 were significantly improved from the untreated fish. In experiment 2, fish were challenged by waterborne exposure to A.hydrophila and F.columnare and either not treated or treated with copper sulphate at 2.1 mg L-1. At the end of experiment 2, the per cent survival of the challenged fish treated with copper sulphate (99%) was significantly higher (P < 0.05) than the non-treated (61%). The results illustrate clear benefit of florfenicol and copper sulphate against a mixed infection of A.hydrophila and F.columnare.
