Iron, RNA, and Adaptation: How Staphylococcus aureus Uses IsrR to Survive Host-Imposed Iron Limitation At the 2025 Theobald Smith Society Spring Symposium, Gustavo Rios-Delgado from Jeff Boyd’s Lab at Rutgers University–New Brunswick presented new insights into how Staphylococcus aureus responds to iro...

How does Staph aureus survive when the host cuts off its iron supply? Gustavo Rios-Delgado discovered that the small RNA IsrR represses iron-hungry pathways—helping the pathogen adapt and persist. More here: wix.to/gdoWNxV #Microbiology #IronLimitation #BacterialRNA #sRNA #Staphylococcus #aureus
