TL;DR: Evidence is presented that extracellular DNA is important for the initial phase of biofilm development by S. epidermidis on polystyrene or glass surfaces under static or hydrodynamic conditions, and that the ext racellular DNA promotes biofilm formation of the remaining population.

TL;DR: This work has suggested that differentiated biofilms may also be the net result of many independent interactions, rather than being determined by a particular global quorum sensing system.

TL;DR: It is suggested that the biofilm-positive/ica-negative strain represents a newly emergent subpopulation of S. epidermidis clinical strains, arising from selection by antibiotics in the nosocomial milieu, which displays a survival advantage in its host environment.

TL;DR: Findings reveal that P. aeruginosa extracellular products are important microbial competition factors that overcome competition with S. epidermidis, and the results may provide clues for the development of a novel strategy for controlling S.EpidermidIS growth in planktonic cultures.

TL;DR: Comparison of the genomes of 13 and 14 isolates of P. aeruginosa mutator populations from an Argentinian and a Danish CF patient showed extensive within-patient genomic diversification, suggesting that the genes were targeted by mutation to optimize pathogenic fitness.
