Pseudomonas aeruginosa can cause chronic infections that are potentially fatal for people with weakened immune systems. In addition, its adaptability and resistance to many antibiotics make infections by P. aeruginosa increasingly difficult to treat. There is therefore an urgent need to develop new antibacterials. Scientists (UNIGE) have identified a previously unknown regulator of gene expression in this bacterium, the absence of which significantly reduces the infectious power of P. aeruginosa and its dangerous nature.
