\n D\u00c9CRYPTAGE – <\/strong>Un cocktail de mol\u00e9cules issues d\u2019anticorps de lamas a montr\u00e9 une efficacit\u00e9 contre 17 des 18 serpents venimeux pr\u00e9sents en Afrique sub-saharienne. Un pas de g\u00e9ant, alors que les th\u00e9rapies anti-venin n\u2019ont pas vraiment progress\u00e9 depuis plus d\u2019un si\u00e8cle.<\/p>\n

Pr\u00e9lever le venin d\u2019un serpent, puis l\u2019injecter \u00e0 un cheval \u00e0 doses de plus en plus fortes. Quelque temps plus tard, r\u00e9colter son sang, le filtrer pour en r\u00e9cup\u00e9rer les anticorps. Enfin, les administrer \u00e0 un patient mordu\u00a0: mis au point au milieu des ann\u00e9es 1890 par\u00a0Albert Calmette<\/a>\u00a0\u00e0 l\u2019Institut Pasteur, le traitement des morsures de serpents n\u2019a depuis pas beaucoup \u00e9volu\u00e9 et son efficacit\u00e9 reste relative. Mais une \u00e9quipe internationale men\u00e9e par des chercheurs danois vient de faire une avanc\u00e9e importante, avec la mise au point d\u2019un s\u00e9rum plus fiable, et surtout \u00ab\u00a0universel\u00a0\u00bb\u00a0: il s\u2019est montr\u00e9 efficace contre 17 des 18 serpents les plus dangereux d\u2019Afrique subsaharienne. Mambas, rinkhals et autres cobras pourraient bien voir leur r\u00e8gne de terreur singuli\u00e8rement affaibli…<\/p>\n

Les travaux pr\u00e9sent\u00e9s\u00a0dans la revue Nature<\/a> \u00a0r\u00e9pondent \u00e0 un v\u00e9ritable enjeu de sant\u00e9 publique\u00a0: l\u2019Organisation mondiale de la sant\u00e9 estime que chaque ann\u00e9e dans le monde, 1,8 \u00e0 2,7 millions de personnes\u2026<\/p>\n
