Pseudomonas aeruginosa, a prevalent cause of hospital-acquired infections, is exhibiting increasing resistance to antibiotics. Recent research has elucidated how this pathogen senses iron, a critical element for its survival.
How a harmful bacterium senses iron
Hard
Led by Aaron Smith, professor of chemistry and biochemistry at UMBC, and collaborators at Oklahoma State University, the study identified a two-protein system within the bacterium. This system detects iron concentrations both extracellularly and intracellularly.
The protein pair functions as a sensitive switch, reprogramming large segments of the microbe's metabolism in response to iron availability. This mechanism offers a promising target for novel therapeutic strategies to combat resistant infections.
