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.

Excited to share the work with @dweisslab.bsky.social‬ and great collaborators on how gene amplification generates dynamic heteroresistance to new beta-lactams, like cefiderocol. We hope drug developers will consider heteroresistance during antibiotic development rdcu.be/euijW
Copy number flexibility facilitates heteroresistance to increasing antibiotic pressure and threatens the beta-lactam pipeline

Research shows: Rifaximin prophylaxis drives resistance to daptomycin, an unrelated, last-resort antibiotic

Rifaximin is used for hepatic encephalopathy in liver patients at high risk for infections, including VRE treated with daptomycin. The antibiotic was thought to pose a low resistance risk
Rifaximin prophylaxis causes resistance to the last-resort antibiotic daptomycin - Nature
Rifaximin use, particularly in patients with liver cirrhosis, may be compromising the clinical use of daptomycin.

A new VRSA variant was found in North Carolina, raising concerns. The emergence of more VRSA variants and locations increases the risk of spread, as it expands the potential to infect different populations and environments, making it harder to control and contain.

Congratulations Lauren! Great work!
Salmonella invades the ileal mucosa to trigger lysine malbsorption, creating a a wave of lysine entering the cecum. Decarboxylation of lysine buffers the cytosol to protect against short-chain fatty acids, enabling the pathogen to invade the cecal ecosystem.
