Phage community: our plasmids for executing phage transposon mutagenesis are now on AddGene and I would love for you to try it out! It is powerful for ID'ing all essential genes and knocking out all non-essentials in a single experiment :) New exp here: www.addgene.org/browse/artic...

Gut phage Acrs Type II CRISPR-Cas systems dominate human gut w/diverse phage Acrs targeting these systems. Widespread family, GutAcraca, adopts similar structures to inhibit Cas9 & regulate its own expression, highlighting phage adaptation to gut ecology www.cell.com/cell-host-mi...

Our lab is excited to share unpublished research on phage defense at the upcoming 2026 Symposium on the Immune System of Bacteria! Today is the last day for abstract submissions: sisb2026.rockefeller.edu Thank you to Marraffini @naamaaviram.bsky.social Seed @jbdsf.bsky.social labs for organizing!

CBASS limits bacteriophage production while maintaining cell viability in Pseudomonas aeruginosa https://www.biorxiv.org/content/10.64898/2026.02.24.707611v1

Woah love it! What a fun time Phage Phriends PhD

Abstract submission is now OPEN for the 2026 Symposium on the Immune System of Bacteria! sisb2026.rockefeller.edu 🗓 May 5–7, 2026 📍 Rockefeller University, New York City ⏰ Abstract deadline: March 16, 2026 Attendance will be capped, be sure to register early and secure your spot. See you in NYC!

Abstract submission is open for the SISB2026 meeting, aka Phage Defense. sisb2026.rockefeller.edu/abstract-sub... The deadline is March 16.

Wow!

Phages are full of genes of unknown function that are likely adaptive in specific conditions. New preprint: Phage TnSeq identifies essential genes rapidly and knocks all non-essentials. We would like to send a pool of phiKZ mutants to anyone wanting it! Reach out tinyurl.com/bdcfrejh

Check this out for the 2026 SISB (phage defense) meeting in NYC. Mark your calendar! (and note the Zoom option, if needed) sisb2026.rockefeller.edu

Our Department of Microbiology & Immunology at UCSF is running a faculty search this year for a new Assistant Professor! Please see the ad below for details. Searching for a great colleague, mentor, and scientist! aprecruit.ucsf.edu/JPF05807

Don’t miss the inaugural Conference on Bacteriophages: Biology, Dynamics, and Therapeutics, October 12–14, 2025, in Washington, DC. A 2.5-day program of invited talks, symposia, workshops, and abstracts will highlight the latest advances. For more info: bit.ly/3JUKLYL

Interested in phage defenses that natively block lytic phage used in therapies? Or do you want to figure out if a phage has a modified genome? Meet the END-nucleases, an enzyme family that can broadly restrict phages with many diverse modifications. From talented post-doc Wearn-Xin Yee!

New to Bluesky and Science here. Are things more positive?

Thank you for moving it over here! Not yet up and running on bsky but learning :)
