  • Title: Relationship between outer membrane protein and lipopolysaccharide profiles and serotypes of enterotoxigenic Escherichia coli isolated in Brazil.
    Author: Nishimura LS, Ferreira LC, Pacheco AB, Guth BE.
    Journal: FEMS Microbiol Lett; 1996 Oct 01; 143(2-3):253-8. PubMed ID: 8837479.
    Abstract:
    The electrophoretic profiles of outer membrane proteins and lipopolysaccharide of sixty-five enterotoxigenic Escherichia coli of different serotypes and virulence-associated factors, toxin and colonization factors were determined. A close relationship between serotype and outer membrane protein and lipopolysaccharide patterns could be observed. No correlation could be found between the electrophoretic profiles and the expression of virulence-associated factors. The observed homogeneity of outer membrane protein and lipopolysaccharide profiles suggested the presence of only a few clones in the samples studied, and supported the use of outer membrane protein and lipopolysaccharide analysis as a useful epidemiological tool in the characterization of enterotoxigenic Escherichia coli isolates.
