Pseudomonas aeruginosa PA14 exposed to the aminothiol cysteamine during growth in synthetic cystic fibrosis sputum media (SCFM2). Pseudomonas aeruginosa PA14 exposed to the aminothiol cysteamine during growth in synthetic cystic fibrosis sputum media (SCFM2)

Derived from coenzyme A degradation in mammalian cells, the aminothiol cysteamine may represent a promising new adjunct treatment for pulmonary exacerbations in cystic fibrosis (CF). This experiment aims to characterise the effect of sub-MIC cysteamine on P. aeruginosa strain PA14. Samples were cultured in SCFM2 (triplicate), and exposed to either cysteamine or a H2O control.
