温和气单胞菌存在于淡水、土壤、淤泥、污水等环境中,有时在海水鱼类中也可观察到,世界各地均有分布~([1])。该菌能引发罗非鱼、鲤鱼、鲫鱼等多种鱼类~([2-6])及其他动物的疾病~([7-9])。采用抗生素类化学药物控制这类疾病会容易导致病原菌产生耐药性~([10-11])。相对而言,用中草药代替抗生素是水产病害防治中的一个发展方向~([12])。有的研究~([13-16])表明,中草药对嗜水气单胞菌等有较好的抑菌和杀菌效果。近年
Aeromonas sobria is present in freshwater, soil, silt, sewage and other environments, sometimes in marine fish species, and is distributed throughout the world ~ ([1]). The bacteria can cause a variety of fish such as tilapia, carp, crucian carp ~ ([2-6]) and other animal diseases ~ ([7-9]). The use of antibiotic chemicals to control such diseases can easily lead to drug-resistant pathogens ~ ([10-11]). Relatively speaking, the use of Chinese herbal medicine instead of antibiotics is a development trend in the prevention and treatment of aquatic diseases ~ ([12]). Some studies ~ ([13-16]) show that Chinese herbal medicine Aeromonas hydrophila has better antibacterial and bactericidal effect. in recent years
