Pseudomonas aeruginosa is an opportunistic pathogenic bacterium present in many ecological niches, such as plant roots, stagnant water or even the pipes of our homes. Naturally very versatile, it can cause acute and chronic infections that are potentially fatal for people with weakened immune systems. The presence of P. aeruginosa in clinical settings, where it can colonize respirators and catheters, is a serious threat. 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 from the University of Geneva (UNIGE), Switzerland, 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. These results, to be published in the journal Nucleic Acid Research, could constitute an innovative target in the fight against this pathogen.
