Congratulations to MD-PhD student, Amanda Velez and all co-authors on our new PNAS paper describing how the innate immune protein calprotectin incapacitates autolysins, inducing tolerance to B-lactam antibiotics. A fun collaboration with Thomas Kehl-Fie. www.pnas.org/doi/10.1073/...

Come join us in Knoxville! The Dept. of Microbiology 🧫🦠 at the University of Tennessee is hiring 2 Assistant Professors (tenure track, 9-month appt.). Microbial Drivers of Chronic Disease: apply.interfolio.com/173153Quantitative Microbe-Plant-Environment Interactions: apply.interfolio.com/173345

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. journals.asm.org/doi/10.1128/...

Discovery of a new class of natural antibiotics with a new mode of action to address antimicrobial resistance, a major unmet need @mcmasteruniversity.bsky.social @nature.com www.nature.com/articles/s41...

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

Multiple faculty positions in the Department of Microbiology and Immunology in association with the Center for Immunology, and the Center for Antimicrobial Resistance at Cornell University

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. www.idse.net/Resistance-S...

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
