When experimentally tested, species from Australia, New Guinea and Japan were also found to be susceptible to the infection. ==History== Crayfish plague first arrived in Europe in Italy in 1859, either with imported crayfish from North America, or in ballast water. After its original introduction in Italy in 1860, it spread quickly through Europe and was discovered in Sweden in 1907, in Spain in 1972, in Norway in 1971, in Great Britain in 1981, in Turkey in 1984 and in Ireland in 1987. In 1959, to bolster dwindling stocks of native crayfish, the signal crayfish was introduced to Sweden.〔 The signal crayfish was known to be resistant, and it was not recognised at that time that it was a carrier of the disease.〔 After 150 years of contact, no resistance has been discovered in native European crayfish. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Crayfish plague」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
