摘要：

A system has been assessed for the identification of Esch coli using a rapid triple chromogenic test which relies on the ability of the organism to produce a beta-galactosidase, a beta-glucuronidase, and indole. Coliforms which had been fully identified were tested by this system. Of 512 non-Esch. coli strains there were no false positives, whereas of 514 Esch. coli strains 486 (94.5%) were found to give positive results. Two hundred and twenty-one coliforms that had been isolated from blood cultures were also tested using the colistrip in advance of, or without knowledge of the API 20E result. The test was found to be 100% specific and 94% sensitive for the 105 Esch. coli strains. The test was rapid, simple to perform and economical.
