Project description:Arrays comparing Pseudomonas aeruginosa growth in a defined synthetic cystic fibrosis sputum medium with and without aromatic amino acids. Additional arrays comparing wild-type Pseudomonas aeruginosa and phhR mutant P. aeruginosa in defined synthetic cystic fibrosis sputum medium.
Project description:The PANarray design (GPL13324) contains the genes of eight P. aeruginosa genomes in non-redundant format, thus allowing identification of expression of non-PAO1 and other P. aeruginosa genes. For the series GSE28152, isogenic isolates were sequentially collected from two cystic fibrosis (CF) patients several years apart. The isolates had not been eradicated in the meantime and represent persister strains. One was an Australian Epidemic Strain-1 isolate and the other a non-epidemic strain. Strains were cultured in an artificial sputum medium (ASMDM) closely resembling CF sputum.
Project description:A collection of sputum samples collected from cystic fibrosis patients. These samples were collected daily from 6 patients for over 1 year.
