On a r\u00e9cemment d\u00e9couvert un nouveau virus dans les profondeurs du Pacifique, plus pr\u00e9cis\u00e9ment dans la fosse des Mariannes, qui est le point le plus bas de l’oc\u00e9an, atteignant pr\u00e8s de 11 000 m\u00e8tres de profondeur. Ce virus appartient \u00e0 la cat\u00e9gorie des bact\u00e9riophages, des organismes qui infectent et se multiplient \u00e0 l’int\u00e9rieur des bact\u00e9ries.<\/p>\n
Les bact\u00e9riophages sont consid\u00e9r\u00e9s comme les formes de vie les plus abondantes sur notre plan\u00e8te, et ils jouent un r\u00f4le crucial dans l’\u00e9cologie des oc\u00e9ans. Ils contribuent \u00e0 r\u00e9guler la taille des populations bact\u00e9riennes et \u00e0 lib\u00e9rer des nutriments essentiels pour l’\u00e9cosyst\u00e8me marin.<\/p>\n
Le nouveau virus, nomm\u00e9 vB_HmeY_H4907 apr\u00e8s une analyse g\u00e9nomique approfondie, se distingue par le fait qu’il est incapable d’infecter les humains. Cependant, les chercheurs estiment qu’il pourrait \u00eatre largement r\u00e9pandu dans l’oc\u00e9an. Sa structure g\u00e9nomique pr\u00e9sente des similitudes avec le groupe de bact\u00e9ries h\u00f4tes halomonas, que l’on retrouve fr\u00e9quemment dans les s\u00e9diments marins et les \u00e9vents hydrothermaux.<\/p>\n
Le Dr. Wang, qui a dirig\u00e9 l’\u00e9tude, a soulign\u00e9 que la d\u00e9couverte de ce virus pourrait ouvrir de nouvelles perspectives de recherche sur les strat\u00e9gies de survie des virus dans les environnements les plus extr\u00eames et isol\u00e9s de la Terre.<\/p>\n
Ces r\u00e9sultats ont \u00e9t\u00e9 publi\u00e9s en d\u00e9tail dans la revue “Microbiology Spectrum”.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
