Assay of Beta-Glucuronidase in Non-coli Escherichia Using EC-Mug Medium and theColilert (Trade Name) System

摘要

Recently, Escherichia species other than Escherichia coli have been isolated frompotable water. Environmental isolates as well as clinical isolates of E. fergusonii, E. hermannii, and E. vulneris were assayed for the enzyme B-glucuronidase by using EC MUG medium and the Colilert system. None of the isolates were positive for the enzyme by either method.
