Discovery yields master regulator of toxin production in staph infections.

Staphylococcus aureus bacteria are among the most frequently used bac’s in scientific research labs. The ‘grape-shaped’ bacteria have started to develop a biofilm: after they adhere to the surface, S. aureus switches to the biofilm-mode of growth and produces a matrix of extracellular polymeric substance (EPS). The production of a biofilm allows S. aureus to aggregate more easily and makes them increasingly resistant to antibiotics. Credit: Martin Oeggerli 2012.
