Previous evidence suggests that Africa is the birthplace of chytridiomycasis. At present, with the increasingly rapid development of international trade in amphibians, the rapid spread and widespread outbreak of chytridiomycosis poses a huge threat to amphibian populations in the world. In this study, according to the entry-exit inspection and quarantine standards of the people~ Republic of China, the impact of amphibian importation from South Africa on ecological security in China was analyzed based on release assessment, contact exposure assessment and consequence assessment, to investigate the risk of chytrid fungus through the importation of amphibians from South Africa to China and the possibility of the colonization and dissemination of chytrid fungus after the introduction. The result of risk assessment of chytrid fungus through the importation of amphibians from South Africa to China and the result of possibility assessment of the colonization and dissemination of chytrid fungus after the introduction were both identified as ＂ moderate＂, which indicated that the importation of amphibians from South Africa to China exhibited a certain risk, and the introduction of chytrid fungus in China would cause certain risk of colonization and dissemination.展开更多

So far, amphibian chytridiomycosis has led to regional extinction of nearly 200 kinds of amphibians and reduced 50% of amphibian populations in the world. In recent years, amphibian chytridiomycosis occurs frequently in Europe. For instance, amphibian chytridiomycosis cases have been found successively in Spain, Germany and Italy, especially in Germany. Currently, with the development of prosperous world trade, the spread of chytrid fungus through trade between countries has posed a huge poten- tial threat to the ecological security of amphibians in China. [ Method] According to entry-exit inspection and quarantine standards of the people＇s Republic of China, in this paper, release assessment, contact exposure assessment and consequence assessment technologies were integrated to obtain the risk assessment result of chytrid fungus from Europe and the possibility assessment result of the colonization and dissemination of chytrid fungus after the introduction. [ Result] The risk assessment result of chytrid fungus from Europe to China was identified as ＂moderate＂, and the possibility assessment result of the colonization and dissemination of chytrid fungus after the introduction was identified as ＂high＂. [ Conclusion] The importation of amphibians from Europe to China exhibits a certain risk. The intro- duction of chytrid fungus in China will cause a high risk of colonization and dissemination.展开更多
