S. aureus has an intrinsic rifampicin resistance mechanism! See the recent study by M. Otto's lab with important clinical implications:

Export by a quorum sensing–controlled drug exporter underlies rifampicin’s strong activity against staphylococcal biofilms | www.science.org/doi/10.1126/...
Export by a quorum sensing–controlled drug exporter underlies rifampicin’s strong activity against staphylococcal biofilms
Rifampicin is more effective against biofilm infections because it targets biofilm-forming mutants that are highly resistant to other antibiotics.

Delighted to share our latest paper - A host-directed adjuvant sensitizes intracellular bacterial persisters to antibiotics. Excellently led by Dr. Kuan-Yi Lu. We think it's a great proof-of-concept that altering immune cell behavior can make antibiotics work better www.nature.com/articles/s41...
A host-directed adjuvant sensitizes intracellular bacterial persisters to antibiotics - Nature Microbiology
The authors developed a screen to find compounds that modulate intracellular Staphylococcus aureus metabolism and discovered KL1, which sensitizes persisters to antibiotics by reversing host-induced tolerance.

CDC reports that the 'nightmare bacteria' with the NDM gene infections rose ~ 70% from 2019–2023 & is resistant to almost all antibiotics.

At GARDP, Shionogi’s approved antibiotic cefiderocol & Bugworks’ BWC0977, now in clinical development, show activity against it.

‘Nightmare bacteria’ cases are increasing in the U.S.
It’s likely that many people are unrecognized carriers of the drug-resistant bacteria, which could lead to community spread, CDC scientists said.
