  • Title: The extraction and analysis of lipopolysaccharides from Pseudomonas aeruginosa strain PAO, and three rough mutants.
    Author: Kropinski AM, Chan LC, Milazzo FH.
    Journal: Can J Microbiol; 1979 Mar; 25(3):390-8. PubMed ID: 110433.
    Abstract:
    Three spontaneously arising rough mutants of Pseudomonas aeruginosa have been isolated by selection for resistance to virulent lipopolysaccharide (LPS) specific bacteriophages. In addition, the first phages specific for rough mutants of P. aeruginosa were isolated. Using these phage and autoagglutination patterns in 4% NaCl and acriflavine, these mutants could be clearly distinguished from the wild-type strain and each other. Chemical analysis of the LPS together with chromatographic resolution of the polysaccharide moieties showed alterations in both O-specific side chains and core regions.
