Emerging infectious diseases pose a serious threat to both biodiversity and human health. Understanding the reasons for disease emergence, identifying the vectors of spread and assessing factors that govern transmission and pathogenicity have now become urgent research priorities. First recognized in 1998, Batrachochytrium dendrobatidis caused chytridiomycosis is an emerging disease that has been implicated in catastrophic declines of amphibians in Europe, North America, Central and South America, and Australia. Our pilot project in 2005 detected this disease on Vancouver Island. In addition, the American bullfrog (Rana catesbeiana), which is believed to be an important vector of B. dendrobatidis dispersal, has been widely introduced in the province and is expanding its range. In western Canada there is potential impact on endangered and threatened amphibians such as the Northern Leopard Frog, Oregon Spotted Frog, and Western Toad. Little is known about

新出现的传染病对生物多样性和人类健康构成严重威胁。了解疾病出现的原因、确定传播媒介并评估控制传播和致病性的因素现已成为紧迫的研究重点。 Batrachochytrium dendrobatidis 引起的壶菌病于 1998 年首次被认识，是一种新出现的疾病，与欧洲、北美、中南美洲和澳大利亚两栖动物的灾难性衰退有关。我们 2005 年的试点项目在温哥华岛发现了这种疾病。此外，被认为是B. dendrobatidis传播的重要载体的美国牛蛙（Rana catesbeiana）已在该省广泛引种，并正在扩大其范围。在加拿大西部，对北豹蛙、俄勒冈斑点蛙和西部蟾蜍等濒危和受威胁的两栖动物有潜在影响。鲜为人知的是
