Abstract:Objective  To study the pathogenicity of Edwardsiella tarda to Andrias davidianus and how to prevent and control it. Methods  Different concentrations of E. tarda (102-108cfu/ml) were used to infect A. davidianus through several distinct routes including living in bacterium-contained environments, feeding in bacterium-contained water, and injection of bacterium-contained water. The pathogenic conditions of this bacterium, its distribution in organs (such as skin, alimentary canal, liver, spleen, and blood), pathological changes of infected A. davidianus, and therapeutic effect of the antibiotic on the infection were recorded. Results  Living in bacterium-contained environments could not cause infectio, and feeding (106108cfu/ml) could cause mild infection, whereas injection (104-107cfu/ml) could cause remarkable infection symptoms, and even death. The bacteria appeared in skin, blood, liver, spleen, and stomach of infected individuals. Antibiotics could relieve symptoms of infected A. davidianus. Conclusion  The results indicated that tolerant infection would appear in A. davidianus, and infection could be cured by sensitive antibiotics.
