Disruption of bacteriophage integration site promotes rapid diversification of multicellular traits in Bacillus subtilis | Microbiology Spectrum Prophages, defined as viruses integrated into bacterial genomes, can reshape bacterial physiology and evolution. Previous studies suggested that disruption of an integration site (spsM) by the SPβ pro...

Another day in the lab☺️🇸🇮 BF_UL with @hanarb.bsky.social and rest of the team🦠

Took a while to make this teaching slide🧑‍🎓, so maybe the community will find it useful, or at least criticism will lead me to its improvement😉 Apologies to all bioinformaticians whose 'babies' are not up there🫢

@hanarb.bsky.social Hannah Bonham masterpiece, capturing Bacillus subtilis (red) lysis💀 by lytic phage. Phage DNA stained with SYBR gold (green). 😎🤓 @erc.europa.eu

An aggregate of phage scientists at gala dinner #SSM2025, interstingly all linked by present/past in 🇩🇰☺️

Phage and bacterial immunity session🤗 opened by @francoisrousset.bsky.social

Beautifull venue Casino Kursaal #SSM2025. Two keynote talks: Pascale Vonaesch🇨🇭and Rafael Pinilla-Redondo🇩🇰, phages starring in both🤩

And the best room view award goes to SSM2025 in Interlaken🇨🇭

Omw to SSM2025 meeting🤗 to give a talk tomorrow @aharms485.bsky.social ppt almost finished😉🦠🆘 (im ok, last emoji corr to my session😅

Bacterial peptide deformylase inhibitors induce prophages in competitors While antibiotics mediate chemical warfare among microbes, their roles in the wild extend beyond direct growth inhibition. Some antibiotics have the potential to mediate interference competition by tr...

Phage people: Rich Losick and I are combing the world looking for T4 rIIB mutant FC0 (also known as P13). FC0 was the starting point for Francis Crick's beautiful 1961 paper on the triplet nature of the genetic code. We want to sequence it. Anyone have it in an ancient stock collection?

I have an opportunity to hire a staff scientist for my lab. Looking for someone with outstanding skillset in ML/statistics, genomics applications; interest in mentoring, strong publication record, PD experience required.

Email CV to me+cc my assistant (see 'contact' on my website). Ad to follow.

High-throughput screening reveals diverse lambdoid prophage inducers Prophages; dormant bacteriophage genomes integrated within the bacterial chromosome, play pivotal roles in shaping microbial communities when awakened. Our current understanding of prophage activation...

Prophage induction - nice study, inducers other than MitC, but also that inducer concentration matters. Search for optimum needed to get highest titers ☝️
