The bacterium Pseudomonas aeruginosa is amongst the main causes of infections and sepsis in people suffering from severe burns. Researchers have succeeded in revealing the dynamics of the pathogen’s physiology and metabolism during its growth in exudates, the biological fluids that seep out of burn wounds. This study allows to follow the strategies developed by Pseudomonas aeruginosa to proliferate and, thus, to guide the development of innovative treatments.
