Pyrazinamide kills Mycobacterium tuberculosis via pH-driven weak-acid permeation and cytosolic acidification https://www.biorxiv.org/content/10.1101/2025.09.26.678883v1

Great collaborative work driven by @pierresantucci.bsky.social which provides clear evidence on the mode of action of a well-known first-line anti-TB drug.

Now out in Trends In Microbiology! Iron-sulfur proteins in mycobacteria: Master regulators of physiology and pathogenesis. Kudos to Valentin Berdal and Wassim Daher. Fantastic exchanges and discussions with leaders in the field: Béatrice Py, Sandrine Ollagnier de Choudens

🎉🎉🎉 Big congrats to Kien Lam UNG, recipient of the 2025 #ATIP-Avenir award!
From decoding antibiotic resistance in M. abscessus to revealing plant hormone transporters in Nature, he is now launching a bold project on how sugar tweaks shape host–pathogen battles. Sweet science! 👏👏👏

Thrilled to share the last work from the lab! Generating a mycobacterial strain lacking all T7SS and studying the contribution of ESX-3 and ESX-4 in M. abscessus pathogenesis. Great collab with E Tocheva and JL Herrmann.

Big Change in TB treatment recommendations. 6 months of RIPE (also called RHEZ) was once the only treatment in town for susceptible TB. Now there's an all oral FOUR months of:
Rifapentine
INH
PZA
Moxifloxacin

A new preprint from Matthew Bogyo. They developed and screened cyclic peptide libraries using mRNA display with a genetically encoded oxadiazolone (Ox) electrophile that was previously shown to potently and covalently inhibit multiple Fph enzymes in S. aureus.

I made a Starter Pack for the Myco & TB community.
Hope to find more good friends here on Bluesky to keep in touch about mycobacterial infections. Please join and repost!
