🩺 Up next: Joe Campbell joined as a co-host for an interview with Dr. Gina Suh, Mayo Clinic ID physician, about what makes the best phage therapy patients, getting phage therapy up and running at her institution, and her current hopes and challenges.

🍅 On deck: Joe and I interviewed Alexander (Sandro) Sulakvelidze, CEO of Intralytix, about his 26-year (!) journey toward getting phage cocktails on the market in the food industry, the 3 clinical trials they’ve got running, and the efficacy data (hopefully) around the corner!

What’s New

Jyot Antani (Yale University) and colleagues developed a microscopy-based technique to measure phage attachment to bacterial cells. This method provides an attractive alternative to the (literally) century-old Phage Adsorption Assay because it…

  • is fast
  • consumes less media
  • provides single-virus readouts
  • does not rely on a theoretical model to estimate adsorption rate

Feel free to reach out with any questions: [email protected]. Requests for advice or collaborations are welcome!

Research paperMicroscopyMethods

François Rousset (Weizmann Institute of Science) and colleagues discovered a new immune signaling molecule: N7-cADPR, which is produced by phage-stimulated TIR proteins. It activates a bacterial caspase, which then degrades essential proteins to curb infection.

PreprintImmune signalling

Tong Zhang (Massachusetts Institute of Technology) and colleagues discovered a bacterial immunity protein that senses two unrelated phage proteins, showing that CapRelSJ46 in E. coli can directly bind two structurally different phage proteins using the same sensory domain. This versatility may help bacterial defenses keep pace with rapidly evolving phages.

Research paperPhage defenseStructural biology

Peter Erdmann Dougherty (University of Copenhagen) and colleagues isolated and sequenced 8 novel phages targeting wheat phyllosphere bacteria, characterizing their genomic, phylogenetic, and morphological traits. They identified DNA modifications, including 13 motif-associated single-stranded DNA breaks in Pseudomonas phage Rembedalsseter, and found related phages in various metagenomes.

Skills

Bioinformatics, Data Science, UX Design, Full-stack Engineering

I am a co-founder of Phage Directory, and have a Master of Human-Computer Interaction degree from Carnegie Mellon University and a computer science and psychology background from UMBC.

For Phage Directory, I design and build tools, and help write and organize Capsid & Tail.

I’ve previously worked at the Westmead Institute, for the Iredell lab at Phage Australia. There, I helped connect bioinformatics outputs and databases like REDCap, Google Drive, and S3-compatible storage systems.

Currently, I’m building and designing AI-centric tools for biology, including experimenting with protein models, biobank databases, AI-supported schema and data parsing, and bioinformatics workflows. Hit me up at [email protected] if you’re curious to collaborate!

Hi everyone,

It’s getting darker and colder outside! Being in California (like Sydney) means it’s easy to forget what it’s like in many parts of the world — cold and wintery! Though we’re now sometimes wearing sweaters, it’s still about 15-20°C ish most days. It’s also easy to forget what’s going on when you’re heads down in work!

Jess is working hard in the lab, and I’ve been building prototypes of various data and research tools in prep for Phage Option 2024, the phage conference in Colombia coming up soon. We’re polishing these up and fixing bugs along the way, but here’s a sneak preview of one of our tools — Breakdown.

Breakdown uses OpenAI’s GPT-4o to break any news article or research paper down into its base arguments and critiques. It does its best to cite its sources from the articles itself. It does a decent job, and can make some papers (e.g. Machine Learning and bioinformatics) papers much easier to read and understand.

We’re still squashing bugs and adding features like multiple languages, but you can try it out here (https://breakdown.labspace.ai/).

We’re also making progress on our profile page system, which is a cross between a personal blog, Linkedin page, CV/resume, and link in bio.

Eventually we want everyone to have their own professional websites, based on their CV and Linkedin, that they can share with others at conferences or when looking for their next position.

Check out Jessica’s personal CV page (https://jess.bio) and Atif Khan’s personal CV page (https://atif.phage.directory/). We’re currently making it easier for people to set up their own accounts, and (finally) be able to edit their own accounts!

Here’s what we published this past month:

How Eligo Bioscience edits gut bacteria with phages

by Jessica Sacher

In this interview between Jessica and Jesus Fernandez from Eligo Bio in France, they talk about how Eligo figured out how to use modified phages to perform base editing of E. coli and Klebsiella — within the mouse gut — without killing the bacteria! Very very cool, and something they deserved a Nature paper for.

Fluorescence, FRAP and flow: 30 days in a phage lab

by Kate Kelly

Last month, Kate Kelly, a high school senior, spent 30 days interning at the Bollyky Lab at Stanford (where Jessica currently works). At the lab, she learned various techniques like bacterial inoculation, plaque assays, flow cytometry, and fluorescence recovery after photobleaching (FRAP), and her main project involved dyeing phages to observe diffusion in biofilms. In this article, she reflects on her experience in the lab.

Our Phage Picks for October 2024!

by Jan Zheng

In this month’s Phage Picks, we highlighted a very well-written post-mortem on Achaogen’s (a former biotech that made antibiotics) demise, and how expensive and difficult putting a new drug on the market is. I also found a neat review paper on atypical (non-dsDNA phages), and a preprint describing a new method for designing phage-based biosensors with novel protein systems on PDMS surfaces. That last one was a doozy.

Protecting Uganda’s banana crops with phages

by Ritah Nakayinga

In this guest article by Dr. Nakayinga, she describes how Banana Xanthomonas Wilt (BXW), a disease caused by Xanthomonas vasicola pv. musacearum, is ravaging banana crops across Uganda. Current management practices are expensive and ineffective, and at this rate could lead to 100% crop loss. Dr. Nakayinga is leading a project at Kyambogo University to develop phage-based biocontrol methods against BXW, where they’ve already isolated phages showing 70-100% efficacy. They’re now working on formulating a phage cocktail and testing effectives in the field!

C&T Throwback!

ChatGPT tips for lab work

C&T Throwback!

I honestly can’t believe it’s been almost exactly a year we’ve been using ChatGPT for work. Where’s the time flown? Seriously. We have so many thoughts on how to use AI for research, and they might not be what you think. We barely use AI to write any text for us!

Mostly we use AI as a partner for thought — from understanding research papers, to searching for information, to formatting data, to writing and refactoring code. We also build it into tools that we use daily (like Breakdown, which I shared above!). If we use it for writing, mostly for those what’s that word again…? moments, or for spell checking. If you’ve noticed, we’ve chose to write more casually, and in our own voices. That’s one of the few ways left to tell that you didn’t just ask ChatGPT or Claude to write everything for… might even leave in a typo ro two. AI after all rarely makes typo mistakes!

We’ll try to get another AI for Work article to you before the end of the year. The year’s almost up, but there’s still so much left to do! Here’s looking forward to November!
