Les Européens ont-ils apporté la lèpre en Amérique ? En explorant cette question, des chercheurs ont dévoilé l'histoire complexe des bactéries responsables de cette maladie. Un beau travail de @nrascovan.bsky.social et ses collègues.

Les Européens ont-ils apporté la lèpre en Amérique ?

Contrairement à ce qu’on pensait, la lèpre existait déjà en Amérique depuis plus de mille ans, véhiculée par une autre bactérie. Ce qui n’a pas empêché les colons de l’apporter aussi.

Pre-European contact leprosy in the Americas and its current persistence

Leprosy, primarily caused by Mycobacterium leprae, is considered a disease introduced into the Americas during European colonization. However, the recent discovery of a second pathogen causing leprosy...

🌎🧬 Leprosy was already endemic in the Americas for 1,000+ years BEFORE Europeans arrived. Scientists analyzed DNA from ~800 samples & found Mycobacterium lepromatosis infecting Indigenous populations centuries before colonization.

Excited to have been a small part of this amazing project lead by @marialopopolo.bsky.social and headed by @nrascovan.bsky.social My part was #ancientDNA labwork for one ancestor that had M. lepromatosis - a form of leprosy present in the US before European contact. Out in #Science -link in thread

Un diente reescribe la historia americana

Una gran investigación de @nrascovan.bsky.social @marialopopolo.bsky.social @avanzich.bsky.social publicada hoy en @science.org

Lo cuento en @agenciasinc.es

Un azote antiguo: la lepra circulaba en América antes de la llegada de los europeos

En colaboración con comunidades indígenas, un equipo internacional de 40 científicos halló ADN de una de las dos bacterias responsables de esta enfermedad estigmatizante en los restos de individuos que vivieron en lo que hoy es Argentina y Canadá hace más de mil años.

Big news in #GlobalHealthHistory today. A species of bacterium that causes leprosy, discovered in 2008 in modern patients, has been proven to have been present in the Americas well before European arrival. More details in 🧵 below: www.science.org/content/arti... #GlobalMiddleAges #histmed #aDNA 🧪
