Beta‐Lactam Antibiotics Promote Extracellular Vesicle Production of Staphylococcus aureus Through ROS‐Mediated Lipid Metabolic Reprogramming

Journal of Extracellular Vesicles, Volume 14, Issue 5, May 2025.
ABSTRACT Bacterial extracellular vesicles (EVs) are natural reservoirs of biological active substances. They exhibit promising application in developing bioproducts such as vaccine, drug‐delivery system and anticancer agent. However, the low yield of naturally secreted EVs during bacterial growth is a bottleneck factor that restricts EV applications ...

Fimsbactin Siderophores From a South African Marine Sponge Symbiont, Marinomonas sp. PE14‐40

Microbial Biotechnology, Volume 18, Issue 5, May 2025.
This work provides evidence of a never‐been‐reported Marinomonas species fimsbactin biosynthesis pathway which produces both the N1‐acetyl‐N1‐hydroxyputrescine‐ and new N1‐acetyl‐N1‐hydroxycadaverine‐containing siderophore structure analogues, an uncommon phenomenon in known fimsbactin producers. This study also discusses the role of enzyme promiscuity

Clinical characteristics and risk factors for escalation to anaphylaxis from non‐severe drug hypersensitivity reaction

Clinical and Translational Allergy, Volume 15, Issue 4, April 2025.
Abstract Background Drug hypersensitivity reaction (DHR) poses significant challenges in clinical practice, with some patients experiencing more severe reactions upon re‐exposure. Understanding the factors contributing to escalation into more severe reactions is crucial for improving patient safety.
