  • Title: Comparison of a competitive enzyme immunoassay kit and the infant mouse assay for detecting Escherichia coli heat-stable enterotoxin.
    Author: Stavric S, Buchanan B, Speirs J.
    Journal: Lett Appl Microbiol; 1992 Feb; 14(2):47-50. PubMed ID: 1367904.
    Abstract:
    A commercial competitive enzyme immunoassay kit, Escherichia coli ST EIA, was compared with the conventional infant mouse assay for sensitivity and specificity in detecting E. coli heat-stable enterotoxin. Thirty-one of 46 strains of E. coli tested were positive by both assays, while 15 strains were negative. The sensitivity of the ST EIA kit was up to 64-fold lower than the infant mouse assay.
