International audience. The Burkholderia cepacia complex (Bcc) is composed of 17 closely related species. These bacteria are widely but heterogeneously distributed in the natural environment, such as soil, water and rhizosphere. Bcc strains are able to colonize various ecological niches by adopting versatile lifestyles, including saprophytism and (positive or deleterious) association with eukaryotic cells. Bcc strains have proven to be very efficient in biocontrol, plant growth promotion and bioremediation. However, they also are important opportunistic pathogens that can cause severe respiratory infections among individuals suffering from cystic fibrosis or chronic granulomatous disease. Therefore, considering that the distinction between plant beneficial and clinical strains is not obvious, biotechnological applications of Bcc strains are currently not allowed. This minireview provides an overview of the wide range of lifestyles that Bcc bacteria can adopt, leading to glimpses into their tremendous adaptation potential and highlighting remaining questions concerning potential implicated mechanisms.
