Description
Summary:A study was carried out to compare the performance of the commercial enzyme detection-based medium, Colisure, with the standard reference MPN and MF methods in detecting chlorine-stressed total coliform bacteria and Escherichia coli in samples simulating contaminated drinking water. Analysis of dilute disinfected samples produced more positive results after 24, 28 and 48 h with Colisure than with the reference method after 48 h. The sensitivity and specificity of Colisure, which were determined by using diluted nonchlorinated samples and verifying positive and negative reactions, was between 96 and 100 per cent for both total coliforms and E. coli. There are 44 references.
