Des chercheurs ont trouv\u00e9 un g\u00e9nome de virus dans des excr\u00e9ments de caribous gel\u00e9s vieux de 700 ans toujours capables d\u2019infecter des plantes en laboratoire. Ils ont analys\u00e9 le mat\u00e9riel g\u00e9n\u00e9tique trouv\u00e9 dans une carotte de glace qui contenait des couches d\u2019excr\u00e9ments de caribous accumul\u00e9s au cours des 4 000 derni\u00e8res ann\u00e9es. Cette carotte a \u00e9t\u00e9 pr\u00e9lev\u00e9e sur un banc de glace dans les montagnes Selwyn \u00e0 la fronti\u00e8re entre les Territoires du Nord-Ouest et du Yukon. Les chercheurs ont d\u00e9tect\u00e9 la pr\u00e9sence d\u2019un virus qui devait \u00e0 l\u2019\u00e9poque infecter une plante arctique faisant partie de l\u2019alimentation du caribou et d\u2019un autre virus capable d\u2019infecter des insectes. Cette \u00e9tude montre comment le g\u00e9nome de virus peut \u00eatre pr\u00e9serv\u00e9 pendant des centaines d\u2019ann\u00e9es dans des conditions glaciales.<\/p>\n
