Bacteriophage continue to have so much to teach us. It's in our interest to understand how they work and impact human & environmental health. New joint work led by @mariandm.bsky.social & @rantahan.bsky.social inferring single-cell latent period & burst size heterogeneity from population dynamics.

I’ve started my SNSF Ambizione Group Leader position at the University of Zurich 🧬 We will study plasmid evolution, plasmid interactions, and CRISPR-Cas systems to better understand antibiotic resistance spread. Very grateful to everyone who supported me along the way.

During my PhD, @milja001.bsky.social and I started counting phage genomes, and tried to make them available in useful formats with useful metadata. We also described the extent of sequenced phage genomes at the time. Five years on, we've had a look at what's changed www.biorxiv.org/content/10.6...

Phage host range: determinants, dynamics and applications

Nature Reviews Microbiology, Published online: 23 April 2026; doi:10.1038/s41579-026-01306-xComprehensive assessment of the host range of phages is a prerequisite for their safe and effective use in multiple applications but is rarely undertaken. This Review outlines the molecular and ecological determinants of phage host range and discusses the importance of these determinants for developing phage-based applications.

Out in @natcomms.nature.com! We show that while most MGEs are blocked by RM systems🛡️, the chromosome is still mobile! 🧬And that cells with defective systems act as "gateways" for HGT. Can you find the hidden Easter egg🐇🥚? Hint: There's a nod to my 🇲🇽 heritage in one of the figures! rdcu.be/fbUC8

Yesterday our paper "Intra-species competition combats vancomycin-resistant enterococci" was published online. We found an enterococcal strain that can outcompete a VRE strain, but loses its potency when given with other non resistant Enterococci. Here is a high res img from the battle in the gut:

New preprint alert!!! 🚀🤓 We are very happy to finally share this with the world — the result of seven years of work and a new tool to study integrons and discover new functions encoded in these bacterial platforms. If you want to know more, here is a thread 🧵 www.biorxiv.org/content/10.6...

New paper 🔔 Collaboration @sullivan-lab.bsky.social Marissa Gittrich led the work Klebsiella phage biology has focused almost entirely on capsulated strains, but capsule loss is the #1 resistance mechanism under phage predation. We used a naturally acapsular host to reveal the receptor landscape

➡️ preprint from the lab! Bacteria have loads of antiviral defences in their mobile genetic elements (MGEs). So when MGEs move between bacteria, the defences move with them, generating a fast turnover of defences in bacteria. But what about the antiviral defence turnover in the MGEs themselves? 🤔 🧵👇

Glad to see our latest work out in Nature Microbiology!! Extremely grateful to everyone involved in the project. Check it out!! 👇🏻👇🏻

Bacteria chromosomes contain Genomic Islands that provide virulence, antibiotic resistance, MGE-defence,... They transfer between cells, but the mechanism of most remains elusive. Here we explore the conjugative capacity of these mysterious Genomic Islands. www.biorxiv.org/content/10.6...

Bacterial genomes encode a rich repertoire of antiphage systems, but we still know surprisingly little about when these systems are actually expressed. In this preprint, Lucas Paoli et al, ask what shapes antiphage systems expression in native contexts. www.biorxiv.org/content/10.6...
