Thrilled to share our preprint where we propose that S. enterica Paratyphi C entered Mexico via European conquest and then diversified locally. More evidence is needed to assert whether or not it caused Cocoliztli (a major contact-period epidemic). Comments welcome!

Ancient genomic insights into Salmonella enterica Paratyphi C in Central Mexico
Salmonella enterica is a widespread pathogen of major global health relevance, with over 2,500 serovars classified into non-typhoidal and typhoidal groups. Within the typhoidal group, S. enterica Para...

Recuerdo con emoción los viajes de muestreo y la impresión de ver por primera vez la inmensidad de la colección del INAH en Santa Lucía 🤩🦣. Es un verdadero privilegio haber sido parte del proyecto. Felicidades a todo el equipo! Se rifaron! 🫰🏽
Lo logramos! @paleogenomics.bsky.social @vvillaislas.bsky.social @mashaals.bsky.social @jcchacond.bsky.social #EduardoArrieta #AngelesTavares #MiriamBravo, #AleCastillo #MarceSandoval, Muchas gracias por su gran entusiasmo, dedicación y entrega. (Ayúdenme a taggear a quienes hacen falta).
La historia de cómo secuenciamos los mamtus 🦣 más tropicales 🏝️ secuenciados al momento la pueden leer aquí 👇https://shorturl.at/KE6Ux. Redactadó por el gran @rpocisv.bsky.social. Muchas gracias Rodrigo por cubrir con tanto entusiasmo la nota sobre nuestro trabajo.

Ready for #ISBA11 meeting. Starting with the pre-conference #PAASTA 🤩 and the welcoming. It’s already being great to connect with peers from Huerta-Sánchez lab @lindaongaro.bsky.social @marcocapo.bsky.social and more (not all in this network). And remember to visit me at my poster No.254 on Friday.

Our paper on the evolution of MUC19 in humans, Neanderthals, and Denisovans is finally out today in Science!
This has been a six-year effort by 13 authors to weave together 3 separate but related evolutionary stories around this one gene (more on thread 🧵).

The MUC19 gene: An evolutionary history of recurrent introgression and natural selection
We study the gene MUC19, for which some modern humans carry a Denisovan-like haplotype. MUC19 is a mucin, a glycoprotein that forms gels with various biological functions. We find diagnostic variants ...
