  • Title: Production of Escherichia coli group I-like heat-labile enterotoxin by Enterobacteriaceae isolated from environmental water.
    Author: Jolivet-Gougeon A, Tamanai-Shacoori T, Sauvager F, Cormier M.
    Journal: Microbios; 1997; 90(364-365):209-18. PubMed ID: 9418038.
    Abstract:
    Strains of Klebsiella oxytoca (2), Citrobacter freundii (2), Enterobacter cloacae (1) and Escherichia coli (1) isolated from environmental water were identified as heat-labile enterotoxin (LT) producing strains by immunological methods and polymerase chain amplification. A 322 bp amplified fragment was obtained with specific primers LTR and LTL, and hybridized to a digoxigenin-labelled LTB probe only under low stringency conditions, and not with a cholera toxin probe. These results suggest that Enterobacteriaceae may produce a LT-like toxin antigenically and genetically related to the LT enterotoxin of E. coli.
