Real-time PCR Detection and Phylogenetic Analysis for Batrachochytrium dendrobatidis in Rana limnocharises from Samples of a Museum
摘要
Abstract
In order to research and prove the chytridiomycosis of amphibians in our country in the history, review the origin of the Batrachochytrium dendrobatidis from the aspects of time and systematic evolution, 39 Rana limnocharises which were collected from Guangdong province and held in museum in 1982 were screened by Taqman-MGB fluorescence probe quantitative polymerase chain reaction to detect the pathogens; and the products of QPCR were cloned and sequenced to identify the origin of the pathogens by sequence alignment and phylogenetic analysis. Finally we got the standard curve: Y = - 3.1 X + 32.65 and the related coefficient: R2 = 0.999 8. There were 12 positive samples were gotten to report the detection rate as 30.8 %. Meanwhile the phylogenetic analysis indicated that a certain extent differentia- tion of the Batrachochytrium dendrobatidis in our country existed. One type of the fungi had altitudinal genetic relationship with the strains from the North America, South America and Europe. Another one was obviously different from the strains in the other areas of the world with special characteristics. The research boosted the earliest record of the Batrachochytrium dendrobatidis in China to 1980s.关键词
