💊 🧬 Insightful dive into in-host bacterial evolution under antimicrobial pressure, a work from @csavin.bsky.social and @pierrelebury.bsky.social in our lab at @pasteur.fr
🦠 14 years, one patient, one superbug
@yersiniaunit.bsky.social scientists tracked Yersinia enterocolitica mutations as it developed antibiotic resistance over 14 years. Unprecedented view of bacterial evolution under treatment pressure 💊

Après que la peste a tout dévasté sur son passage, que devient-elle?
Lors de chacune des trois pandémies historiques, un même mécanisme a conduit à la mise en sourdine de sa virulence, ce qui favoriserait sa persistence dans des populations de rongeurs fragmentées.

Picking up our publication on Black Death and plague pandemics: here are interesting historical thoughs about the well known but deceptive (not so) medieval plague doctor costume
There is some news about the Black Death... are we taking bets on how the media is going to illustrate it?

Two great papers in @science.org this month on the #evolution of #vector-borne #pathogens

1 #Yersinia pestis attenuates virulence over 3 pandemics

2 Ancient #Borrelia genomes trace the rise of louse-borne relapsing fever

Fascinating reads (links below)

New updates on our plague vaccine: we now report that the type 3 secretion system is important for innate and adaptative immunity mechanisms and useful for protection in our live Yersinia pseudotuberculosis producing the F1 pseudocapsule 👇

Following criticisms raised concerning our article www.nature.com/articles/s41..., we just confirmed our original conclusions, demonstrating that the rs2549794 variant near the ERAP2 locus displays a strong positive selection signal associated with the Black Death ☠️
