Abstract excerpt
De-O-acylated lipopolysaccharides (LPS) of three polymyxin-resistant Salmonella typhimurium pmrA mutants and their parent strains were analysed by 31P-NMR (nuclear magnetic resonance) in order to assess, in relation to polymyxin resistance, the types and degree of substitution of phosphates of th...
