I had a great time at the JIHS in Tokyo yesterday, presenting my work on pre-colonial M. lepromatosis-leprosy in the Americas followed by great discussions on leprosy. Thank you so much for hosting me!

I am still wrapping my head around the amazing week that I had first at our @spaam-community.bsky.social conference #SPAAM7 followed by 3 days of @isba11.bsky.social in Torino. A conference that ended with a prestigious award. I am very grateful and honoured @isbarchaeology.bsky.social

An August addendum to this 🧵 on new studies documenting the presence of Mycobacterium lepromatosis in the pre-Contact Americas. @marialopopolo.bsky.social, lead author of the study in @science.org that came out in May, has won the @isba11.bsky.social Best Paper prize! bsky.app/profile/nras... Kudos!

@isba11.bsky.social Super happy and proud for @marialopopolo.bsky.social and @avanzich.bsky.social who got the prize to the best paper at #ISBA11 in Turin. Thanks to the jury for this honor!

Thank you @spaam-community.bsky.social 🙏 a community full of amazing scientists but also dear friends who accompanied me during the journey of my PhD and from whom I've learnt a lot ✨️

🌎🧬 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. #Leprosy @marialopopolo.bsky.social @nrascovan.bsky.social

And this blogpost for #WorldLeprosyDay2025 adds in the story for the "medieval" Pacific world: constantinusafricanus.com/2025/01/26/l.... With this latest work by @marialopopolo.bsky.social @nrascovan.bsky.social et al., we now have the outlines of a complete global picture. #histmed #MedievalSky

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 🧪

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 www.agenciasinc.es/Reportajes/U...

Did leprosy exist in the Americas before European invasion? Our lab #aDNA study at @institutpasteur.bsky.social supervised by @nrascovan.bsky.social in collab with @avanzich.bsky.social (CSU) finds M.lepromatosis in pre-colonial Ancestors from North and South America www.science.org/doi/10.1126/...

⏰ Extended deadline to submit an abstract to SPAAM7 conference. You have time till 1st of June! #aDNA #ancientmetagenomics #metagenomics #pathogens

Super excited for a summer sessions of SPAAMtisch Seminars! 🎉 On May 14 at 4pm CET (NOW LIVE!), Luis Victoria Nogales dives into early European farming via #sedaDNA🧬🪓 Do not miss this seminar and join us at this link: ut-ee.zoom.us/j/9696197212... #aDNA #ancientmetagenomics

Many zoonotic diseases are believed to have emerged during prehistory, but can we actually identify their past host range using ancient DNA? In the first publication of the Key Lab we present a 4000y old Yersinia pestis genome reconstructed from domesticated sheep. 🧵 www.biorxiv.org/content/10.1...
