Les chercheurs ont ensuite pu extraire l’ADN humain des cellules du cuir chevelu pi\u00e9g\u00e9es dans la substance, qui est g\u00e9n\u00e9r\u00e9e par les poux femelles pour attacher leurs \u0153ufs, appel\u00e9s lentes, aux cheveux humains. Mikkel Winther Pedersen de l’Universit\u00e9 de Copenhague a expliqu\u00e9 que le \u201cciment nit\u201d contenait autant d’ADN qu’une dent humaine, et deux fois plus que ce qui est g\u00e9n\u00e9ralement r\u00e9cup\u00e9r\u00e9 sur des os humains. L’ADN extrait du ciment nit, a-t-il ajout\u00e9, a r\u00e9v\u00e9l\u00e9 le sexe des h\u00f4tes humains; une migration il y a environ 2 000 ans des plaines du nord de l’Amazonie vers le centre-ouest de l’Argentine; et des traces d’un virus d\u00e9couvert en 2008. Le polymavirus \u00e0 cellules de Merkel est g\u00e9n\u00e9ralement rejet\u00e9 par une peau humaine saine, mais lorsqu’il p\u00e9n\u00e8tre dans le corps, il peut provoquer un cancer de la peau. Sa pr\u00e9sence sur l’une des momies sugg\u00e8re que les poux de t\u00eate peuvent propager le virus, a expliqu\u00e9 Pedersen.
