Sensitivities of Vibrio vulnificus to Chinese Herbs and Effect of Medicinal Bath on Vibrio vulnificus.

Vibrio vulnificus can cause rotten-skin disease in marine fish aquaculture, resulting in a large number of deaths. 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, Chinese rhubarb, pomegranate bark, mentha and clove have strong bacteriostatic effects. The Chinese medicinal herb bath showed good control effect on V. vulnificus. [ABSTRACT FROM AUTHOR]
