Competence development in the human pathogen Streptococcus pneumoniae controls several features such as genetic transformation, biofilm formation and virulence. This study shows that competence activation is crucial for optimal host adherence, via a mechanism dependent on the fratricin CbpD, which exposes virulence factors to the cell surface.
A recent paper from #AppEnvMicro, “Streptomyces coelicolor Vesicles: Many Molecules To Be Delivered," explores the production & characterization of membrane vesicles in liquid cultures of S. coelicolor M145. Find it in the MBP New and Notable collection: https://asm.social/11r

EMBO Workshop Great Wall Symposium program is comming soon … Dear Cell Wall community, The 7th Great Wall Symposium was supposed to take place next 24-26 th September 2021, The Vila Galé Sintra Hotel, in Portugal. However, given the current pandemic situation, we, the organizers, decided to postpone the meeting to September 2023, as we […]
News alert: Some bacteria have histones y'all. Shawn Laursen from @[email protected] shows how they bind DNA in VERY unexpected way, defying common 'histone logic'. Check out our preprint with @[email protected] @[email protected] and Socket lab
https://www.biorxiv.org/content/10.1101/2023.01.26.525422v1. Very exciting!
First exploration of pili in #archaea with @[email protected] ! Haloferax forms pili that promote adhesion and biofilm formation. We found that 1 of the 6 pilin isoforms was sufficient for type IV pilus biogenesis. No pili -> no surface attachment https://www.biorxiv.org/content/10.1101/2023.01.20.524888v1

Watch bacteria swap DNA in real time 🔬
Using new genetic reporters, this paper "uncovers the choreography of conjugation reactions in live bacteria."
The videos are beautiful & show how individual plasmids move between microbes. 🍿

Conjugation is a contact-dependent mechanism for the transfer of plasmid DNA between bacterial cells. Here, Couturier et al. use live-cell microscopy to visualise the intracellular dynamics of conjugation in real time, revealing a molecular strategy that allows the sequential production of factors involved in establishing, maintaining and disseminating the plasmid.
Bacteria replicate DNA at crazy speeds & accuracy. 💨
If DNA polymerase was a USPS truck, and each home was a single nucleotide:
This truck would deliver to every home in the U.S. in 65 hours. It would do this about 4 times without making a single mistake.
