Inhibitory effects of hypertonic saline on P. aeruginosa motility

J Cyst Fibros. 2008 Jul;7(4):267-269. doi: 10.1016/j.jcf.2007.11.009. Epub 2008 Jan 31.

Abstract

Salt transport defects in CF lungs predispose to overwhelming and fatal respiratory infection caused by Pseudomonas aeruginosa. Motility of this organism is central to pathogenesis in a number of settings. Incubation of numerous strains of P. aeruginosa with hypertonic saline caused a concentration-dependent decrease in bacterial motility. Reduction of P. aeruginosa virulence through this effect may contribute to clinical efficacy of hypertonic saline aerosols in CF patients.
