Effect on Pseudomonas aeruginosa alginate expression of direct plating and culture of fresh cystic fibrosis sputum on to pseudomonas isolation agar containing subinhibitory concentrations of roxithromycin and rifampicin.

Abstract

The effects of subinhibitory concentrations of roxithromycin (16 mg/L) or rifampicin (16 mg/L) on alginate production by Pseudomanas aeruginosa were investigated. The weight of purified alginate from antibiotic-free cultures was significantly greater (52.5 +/- 24.0 mg, range 22.4-109.5), compared with alginate from cultures bacteria exposed to sub-MIC of… (More)
