🚀New preprint from our lab!
I am very excited to finally share what has been the main focus of my PhD for the past almost 3 years! It is about viral dark matter and a powerful tool we built to shed light on it. 🧬💡

🚨Preprint alert - this is a big one! We transfer the revolutionary power of TnSeq to bacteriophages.
Our HIDEN-SEQ links the "dark matter" genes of your favorite phage to any selectable phenotype, guiding the path from fun observations to molecular mechanisms.

Quite astounding that we are still pushing this kind of program, despite the Bouchard report and all the numerous stories of ‘stars’ coming from abroad who come to Canada, but keep their former lab, and then go back after 5 years because Canada is too cold or whatever.

Time for some insights into our latest #preprint
Using cryo–electron tomography, we peeked inside different #Mtuberculosis strains, and a couple of other mycobacteria.🧐 Surprise: some species, especially the host-adapted ones, build intracytoplasmic membranes (we call them MIMs)! 🦠
