Assay for beta-Glucuronidase in Species of the Genus 'Escherichia' and ItsApplications for Drinking-Water Analysis

摘要

Recently species of the genus Escherichia other than E. coli have been isolatedfrom potable water. Environmental isolates as well as clinical isolates of E. adecarboxylata, E. blattae, E. fergusonii, E. hermannii and E. vulneris were assayed for the enzyme Beta-glucuronidase using EC MUG medium and the Colilert system. None of the isolates were positive for the enzyme by either method. (Copyright (c) 1991 American Society for Microbiology.)
