[Method] in vitro anti-bacterial effects of 5 kinds of Chinese herb extracts like Galla Chinensis,Syzygium aromaticum,Salvia miltiorrhiza,Punica granatum L. and Terminalia chebula Retz on Ameromonas hydrophila were studied; furthermore,cure rates of the Chinese herb extracts with better anti-bacterial effects were determined to find out the optimal drug dosage. [Result] Under the same experimental conditions,Galla Chinensis,Punica granatum and Terminalia chebula Retz had relatively strong anti-bacterial effects on Ameromonas hydrophila,among them the anti-bacterial effect of Galla Chinensis was significantly higher than those of the others （P0.05）. The optimal treatment dose of Galla Chinensis treating bacterial septicemia caused by Aeromonas hydrophila was that they were treated with medicated bath for 40 min by 0.5 mg/ml Galla Chinensis extract,and the cure rate was 100%. [Conclusion] The research provides a scientific drug basis for the control and prevention of outbreak bacterial diseases of fish.展开更多

The occurrence of rotten-skin disease is becoming severer and severer, leading to serious economic losses. In this study, the sensitivities of V. vulnificus to the 18 kinds of herbs, such as stone calamus and Chinese rhubarb, were determined using the agar diffusion method （susceptibility paper）. The results showed that Chinese gall, dark plum, sea buckthorn and eucalyptus leaves have bacteriostatic and bactericidal effects, while sappan wood, Chi- nese rhubarb, pomegranate bark, mentha and clove have strong bacteriostatic ef- fects. The Chinese medicinal herb bath showed good control effect on V. vulnificus.展开更多
