Some bacteria make circular proteins that stop foodborne pathogens. A new 𝐦𝐁𝐢𝐨 paper from APC researchers identifies pumicyclin A from B. pumilus, active against Gram-positive bacteria such as Listeria & B. cereus. 📰 buff.ly/LIo1KlU @colinhillucc.bsky.social @colinthb.bsky.social #Bacteriocins
Research announcement: mBio paper from University College Cork identifying and characterising pumicyclin A, a novel circular bacteriocin from Bacillus pumilus, shown with circular author headshots and the UCC logo above the paper title.

New APC paper in Nature Communications. First author Tatiana Borodovich and colleagues examine how capsids drive large-scale DNA transfer in the gut. The study forms part of the research programme of Prof. Andrey Shkoporov's group at APC. www.nature.com/articles/s41... #Bacteriophage #Microbiome

Our recent preprint examining mechanisms that enable Bacteroides phages to persist with their host in the human gut #bacteroides #phage #gut www.biorxiv.org/content/10.1...
biorxiv.org
Adaptations in gut Bacteroidales facilitate stable co-existence with their lytic bacteriophages
Background Bacteriophages (phages) and bacteria within the gut microbiome persist in long-term stable coexistence. These interactions are driven by eco-evolutionary dynamics, where bacteria employ a v...

Well done to Knox et al. on their study examining the effects of Bifidobacterium fermentation on infant formula! #Bifidobacterium #InfantFormula www.sciencedirect.com/science/arti...
sciencedirect.com
Bifidobacterium fermentation with infant formulas is associated with benefits for gut and brain barrier function
The gut and blood-brain barrier are essential components of the microbiota-gut-brain axis and are influenced by diet, particularly in infancy. Breast …
