🧪 New research by @basler-lab.bsky.social reveals a surprising microbial trade-off: Pseudomonas aeruginosa activates a defense program to survive “speargun” attacks from rival bacteria, but this defense makes it more vulnerable to antibiotics. @unibas.ch @snsf.ch @nccr-antiresist.bsky.social 👇

Very happy to see this work published! We unveil a plasmid-chromosome crosstalk by showing that pOXA-48 encodes for a regulator that mediates the transcription of an enterobacterial chromosomal operon, resulting in a growth benefit for the plasmid-carrying bacteria! www.nature.com/articles/s41...

A plasmid-chromosome crosstalk in multidrug resistant enterobacteria - Nature Communications

The authors describe a new crosstalk between a globally disseminated carbapenem resistance plasmid and clinical enterobacteria clones. This crosstalk provides a fitness advantage to the plasmid-carryi...
