Selective elimination of donor bacteria enables global profiling of plasmid gene expression at early stages of conjugation Abstract. Conjugative plasmids are a major driving force for the dissemination of antimicrobial resistance. During conjugation, plasmid DNA is transferred

academic.oup.com/nar/article/... Collaboration with Y. Yamaichi. Killing donor bacteria in conjugation mixes using water enables transcriptomic profiling of early plasmid genes ! Superb tool for studying zygotic induction of these early genes, which include anti-SOS and anti-RM factors. #microsky

I have been a member of the ASM for over 20 years. As a Canadian scientist and member of the LGBTQ+ community, I will not support a society in a country that demonstrates a complete lack of respect for Canadians and minorities.
I won't renew my membership for 2026.

Great opportunity! www.usherbrooke.ca/emplois/offr...

The Palestine Exception in Science (opinion) A small act in recognition of Palestinian humanity during a scientific presentation should not have been met with a reprimand.

Thanks to @insidehighered.com for publishing my perspective about being reprimanded by the Gordon Research conference after my display of empathy for Palestinian victims of genocide.

Large study of scientists who move their labs reveals how location drives productivity Concentrating funding at high-powered universities can maximize output, paper argues, but may sacrifice broader benefits

Needless to say, it also helps when the institution provides professional help for grant writing, which is not the case in smaller universities.

Join the Blokesch lab (@EPFL) as a postdoc in Molecular Microbiology 🤩
Study Vibrio cholerae defense systems (phage/plasmid) in a dynamic, collaborative environment in Lausanne close to Lake Geneva in 🇨🇭!
Please visit my lab's webpage for details about the position and how to formally apply.

🔬 Ph.D. position in Environmental Microbiology
The LCPME is offering a 3-year Ph.D. position to work on the biology of conjugative plasmids carrying antibiotic resistance genes in environmental contexts. This project will combine bacterial genetics, microcosm experiments, and bioinformatic.

Conjugative transfer inhibition of IncA and IncC plasmids by pervasive SGI1-like elements via relaxosome assembly interference Broad-host-range IncA and IncC conjugative plasmids propagate multidrug resistance in bacteria and mobilize chromosomal resistance islands, including Salmonella Genomic Island 1 (SGI1) across genera. ...

Réservez les dates! Le BiSP (bactériologie intégrative, symbiose et pathogénèse) aura lieu le 5 et 6 novembre à l'Université de Sherbrooke - un événement qui sera en "symbiose" avec le MicrHub, rencontre annuelle de tous les microbiologistes de Sherbrooke. À ne pas manquer!

Many thanks! I agree, there are probably intermediates out there.

It took me longer than I wanted, but I finally have an official lab website! www.fjplab.com

Large serine integrases utilise scavenged phage proteins as directionality cofactors Abstract. Recombination directionality factors (RDFs) for large serine integrases (LSIs) are cofactor proteins that control the directionality of recombina

Officially published now: RDFs for Large Serine Integrases that are moonlighting proteins.
With collaborators the Olorunniji group @femijohn.bsky.social we find the TG1/phiC31 family RDF is an SSB, and the Bxb1 RDF has the fold and activity of an exonuclease.

Can random sequences encode meaningful functions and allow de novo gene birth? To explore this, Michael Laub and I screened 100 million random genes, without sequence similarity to natural genes, for their ability to rescue growth arrest of E. coli cells producing the ribonuclease toxin MazF.
