Congrats to Chase Morgan @phagemorgan.bsky.social and the phage team!

🚀 Just 5 days left to apply!
We’re hiring — and we’d love for you to join our team. If you’re passionate about AI, health and infection research, this is your moment to start an independent junior research group at HZI in one of Europe's most research-rich regions.
⏰ Deadline: March 30

Excited to share the first preprint from the lab! We show that ApeA defends against RNA phage infection by cleaving the phage genome:

A phage protein screen identifies triggers of the bacterial innate immune system - Nature Microbiology A library of 400 phage protein-coding genes is used to find a trove of antiphage systems, revealing systems that target tail fibre and major capsid proteins.

I’m thrilled to share our work on phage triggers of the bacterial immune system in its final form @natmicrobiol.nature.com www.nature.com/articles/s41...

Happy to share our recent preprint:
"DNA-intercalating antiphage molecules trigger abortive infection through mutual destruction and synergize with bacterial immunity"

Bakterien gegen Mensch: Wer wird gewinnen?

Bakterielle Infektionen können uns krank machen oder sogar zum Tod führen. Zudem wirken Antibiotika durch zunehmende Resistenzen immer schlechter.

Strain displacement in microbiomes via ecological competition - Nature Microbiology Mathematical modelling and experimental tests reveal principles that govern displacement of a resident strain by an invader in microbial communities.

Can we leverage bacterial competition for targeted replacement of harmful strains? Maybe! Our recent piece in @natmicrobiol.nature.com provides a theoretical framework and a set of experiments to show what it might take: www.nature.com/articles/s41...
