(b) Protein expression in P. aeruginosa CF isolates in comparison to PAO1 determined in vitro in minimal medium M9 [99], rich medium LB [98, 102, 103] or in sputum-like media SCFM [99] or ASMDM (artificial sputum medium with high molecular mass DNA and mucin) [103], for the 15 proteins identified as expressed in vivo. The gene discussed is MUC5AC; the disease is cystic fibrosis.
