Updates

Garyk Brixi (Arc Institute and Stanford University) and colleagues have expanded on Evo 1, which was trained on prokaryotic and phage genomes, to create Evo 2, now the largest AI model in biology. It was trained on 9.3 trillion nucleotides from 128,000 genomes across all domains of life (spanning bacteria, archaea, phages, humans, plants, and other single-celled and multi-cellular species). It identifies genetic patterns, predicts mutation effects, and designs genome-scale sequences. Evo 2 is fully open-source — play with it here!

GenomicsAI and biologyPreprint

Benjamin Adler (University of California, Berkeley) and colleagues published CRISPRi-ART for phage functional genomics, a new broad-spectrum phage functional genomics platform. It leverages RNA-targeting dCas13d to selectively interfere with protein translation, allowing measurement of phage gene fitness at a transcriptome-wide scale. It works for all kinds of phages, and has already identified more than 90 previously unknown genes important for phage fitness!

Melissa Cammuso (The Ottawa Hospital) and colleagues have published a preprint in medRxiv on the first use of phage therapy in Canada for life-threatening, MDR Staphylococcus epidermidis periprosthetic joint infection. This ‘n of 1 trial’ describes how the phage was administered intra-articularly and intravenously, leading to sustained clinical improvement.

Los Angeles Biotech startup Parallel Health has announced an expanded protocol for personalized skin treatments using microbiome science and phage therapy. Their approach combines microbiome testing, custom phage serums, telehealth, and prescriptions to address various skin conditions.

Maria Touceda-Suarez (University of Arizona) and colleagues compiled a report on last year’s successful International Soil Virus Conference 2024, showing key developments in soil viral ecology and recommendations for future research in this rapidly advancing field. Also, participation at this meeting doubled since 2022, with 38% early-career researchers attending from 10 countries!

Researcher (Faculty and Technologists) in Molecular Biology of Phage-Bacteria-Animal Symbioses at One Health Microbiome Center, Penn State University in University Park, PA, USA

The Bordenstein lab in the One Health Microbiome Center at The Pennsylvania State University seeks multiple Researchers. The Researcher position (non-tenure track faculty) will focus on the use of Drosophila transgenic expression, genetic editing techniques, fitness assays, reproductive tissue dissections, fluorescent and electron microscopy, microinjections, and team management to understand the genetics and mechanisms of how endosymbionts and their phage genes modify reproduction in animals.

Newbie with questions on phages: I am an absolute newbie to phages, but, I figured here would be a good place to ask. Anyone know of any phages capable of targeting Candidatus Liberibacter Asiaticus? Anyone do any research with phages on this?

Hi phage phans,

Look at that, we’re on Issue 300! That’s a really big number!

When we first started Capsid & Tail, we only planned to write maybe 30 issues. Years later, we’re still going strong!

Jessica’s still heads down working on Pf and ΦX174 phages at Stanford, while I’m heads down working on Evergreen and prototyping some other projects — there’s so many fun experiments to share, but still so many bugs to fix.

I’ve also been messing with the Phage Directory website, and we’re ready to flip the switch to the new site soon. Excited to share!

Here’s what we published this past month:

First food, then pharma: How Intralytix played the long game with phages

by Jessica Sacher

Jessica recaps her podcast conversation with Sandro Sulakvelidze about Intralytix’s 25-year-long journey, from startup to one of the few profitable phage companies.

Sandro shares how growing up in phage-friendly Tbilisi led him to found Intralytix after witnessing US patients dying from infections that could have been treated with phages, and explains their strategic pivot to food safety applications before moving into human therapeutics. The conversation covers Intralytix's experience with FDA approvals, their AI-driven manufacturing innovations, and Sandro's vision for the future of phage therapy.

Building a phage lab: a journey of resilience, teamwork, and sticky situations

by Silvia Würstle, Maria J.G.T. Vehreschild, Simone Lieberknecht-Jouy, Fedja Farowski

In this article, Dr. Silvia Würstle and her team share their experience transforming an abandoned, water-damaged space into a modern phage laboratory at the University Hospital in Frankfurt, Germany. The team describes their journey from dealing with warped floors and empty rooms to creating a fully-equipped, certified lab space, highlighting challenges like navigating hospital ordering systems without product photos, securing specialized equipment, and learning technical specifications on the fly. Despite the obstacles, they successfully built three lab spaces, an office, a common room, and a storage area with support from hospital staff and the global phage community.

Setting up systems to make phages available for all

Throwback: I really loved this article from last year, where Jessica laid out our entire process for setting up our phage lab’s system. I think this article pairs very well with both Sandro’s and Silvia’s Hero’s Journey stories!
