New preprint! #MicroSky Led by @ayaiizuka.bsky.social & Maria Vittoria Mazzuoli, we ask what helps Staphylococcus aureus enter, survive inside and evade treatment in human monocytes. www.biorxiv.org/content/10.6...

Staphylococcus aureus Mnh1 cation–proton antiporter promotes phagocytic uptake and intracellular survival in human monocytes
While Staphylococcus aureus is predominantly an extracellular human commensal, it can also exhibit an intracellular lifestyle that enables its persistence within diverse host cell types, including mon...

First week as a visiting scholar in the @nizet.bsky.social lab at @ucsdhealthsci.bsky.social ! Excited to learn from everyone in the lab and very grateful for the warm welcome. Already in love with SoCal! ☀️ 🏄‍♀️

OUT NOW! We uncovered a coordinated regulation of CRISPR-Cas9 immunity and virulence in GBS. Could this enhance bacterial immune repertoires during infection? Have a read: 🔗 www.nature.com/articles/s41... 👏 congrats to all co-authors!

HU promotes higher order chromosome organization and influences DNA replication rates in Streptococcus pneumoniae
Abstract. Nucleoid-associated proteins (NAPs) are crucial for maintaining chromosomal compaction and architecture, and are actively involved in DNA replica

1/ 🔬 Our work, "Dynamic transitions of initiator binding coordinate the replication of the two chromosomes in Vibrio cholerae", is now published in Nature Communications. Here's a thread on how we think Chr1 and Chr2 replication is coordinated in Vibrio. 🧵 Link : www.nature.com/articles/s41...

Make-or-break prime editing for bacterial genome engineering
CRISPR-Cas9 has revolutionized genome engineering by allowing precise introductions of DNA double-strand breaks (DSBs). However, genome engineering in bacteria is still a complex, multi-step process r...
