LES INCROYABLES SC\u00c9NARIOS DE LA FIN DU MONDE (2\/6) – <\/strong>Cr\u00e9\u00e9es comme l\u2019image invers\u00e9e des pathog\u00e8nes naturels, les bact\u00e9ries miroir pourraient r\u00e9sister \u00e0 tous leurs pr\u00e9dateurs. Si elles se propagent, leur impact sur les \u00e9cosyst\u00e8mes pourrait \u00eatre incontr\u00f4lable. Et pourtant, certains chercheurs n\u2019ont pas renonc\u00e9 \u00e0 les fabriquer…<\/p>\n

Elles ne devaient jamais quitter le laboratoire.\u00a0Les bact\u00e9ries miroir<\/a>\u00a0\u00e9taient cens\u00e9es rester confin\u00e9es, surveill\u00e9es, neutralis\u00e9es. Pourtant, quelques-unes se sont \u00e9chapp\u00e9es et en quelques mois elles se sont multipli\u00e9es, ont franchi les fronti\u00e8res, infiltr\u00e9 les \u00e9cosyst\u00e8mes\u2026 et commenc\u00e9 \u00e0 tuer humains et animaux. L\u2019\u00e9chapp\u00e9e de ces pathog\u00e8nes qui n\u2019auraient jamais d\u00fb quitter les paillasses \u00e9tait-elle intentionnelle\u00a0? \u00c9tait-ce le fruit d\u2019un criminel, ou un malheureux accident\u00a0? Toujours est-il que les bact\u00e9ries miroirs ont colonis\u00e9 l\u2019environnement et se sont attaqu\u00e9es \u00e0 un tr\u00e8s large spectre d\u2019\u00eatres vivants incapables de s\u2019en d\u00e9fendre, des micro-organismes du sol aux \u00eatres humains.<\/p>\n

Pour comprendre ce qu\u2019est une bact\u00e9rie miroir, imaginez vos deux mains\u00a0: elles semblent identiques, partagent la m\u00eame structure, et pourtant, il est impossible de les superposer parfaitement. L\u2019une est le reflet de l\u2019autre\u00a0: semblables, mais invers\u00e9es. En chimie, ce ph\u00e9nom\u00e8ne porte un nom&nbsp\u2026<\/p>\n
