Abstract:While several environmental factors contribute to the evolutionary diversification of the pathogenic bacterium Pseudomonas aeruginosa during cystic fibrosis lung infections, relatively little is known about the impact of the surrounding microbiota. By using in vitro experimental evolution, we show that virulent subpopulations of P. aeruginosa are maintained in the presence of interspecies competition by Stenotrophomonas maltophilia, Staphylococcus aureus, or them both, but lost in the absence of competition du… Show more
