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...

Looking to hire a postdoctoral associate to examine how antibiotics frequently fail in vivo and identifying new ways to make them work better. unc.peopleadmin.com/postings/306...

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

For our first post on Bluesky, we're excited to share our recent work published in mBio @asm.org! Led by PhD student @madeofmicrobes.bsky.social, we show that flagellar motility and interactions with the mucus environment influence Pseudomonas antibiotic tolerance.

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

Delighted to share our new study. A collaboration with the Thurlow lab. Antibiotic resistance rapidly emerges and thrives in diabetic mice. A worrying coming together of two major and growing health problems worldwide www.science.org/doi/10.1126/...

#WeekendRead! Ahn, Arthur &co show @CellHost&Microbe that pathogenic E. coli produce a metallophore that sequesters zinc in macrophages, stabilizing HIF1a & driving fibrosis in #IBD mouse models and Crohn Disease patients! www.sciencedirect.com/science/arti...

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.

Worrisome

During the 2022–23 school year, CDC reports DTaP vaccine coverage dropped to 92.3%; vaccine exceptions rose 10%

As a pediatrician, few patients were as precarious as the infant with pertussis hospitalized for weeks in the ICU with severe apnea spells requiring repeated resuscitation

Congratulations Lauren! Great work!

Calling all microbiologists! Registration is open for the Mid-Atlantic Microbial Pathogenesis Meeting, February 2-4, 2025.! Abstract deadline is 12/8/2024, but don't wait, filling fast. Check it out at mampm.org.

Publication Alert! Happy to share our new work published in CellReports of a collaboration with the Zychlinsky Lab (Max Planck Institute for Infection Biology). "Histone H1 kills MRSA". cell.com/cell-reports.... Enjoy!

Great list. Please add me. I hope all is going well with you.
