Use of the ISO 9308-1 procedure for the detection of E. coil in water utilizing two incubation temperatures and two confirmation procedures and comparison with defined substrate technology.
Disinfected and non-disinfected samples have been used to determine the accuracy of the ISO procedure (ISO 9308-1) for detection of E. coli in drinking water. Samples were analysed using the ISO procedure at both 36 and 44 degrees C and using the defined substrate technology method Colilert-18/Quanti-Tray (Colilert-18). Utilizing the confirmation procedure described in ISO 9308-1, large numbers...
متن کاملComparison of Colilert-18 with miniaturised most probable number method for monitoring of Escherichia coli in bathing water.
The purpose of this equivalence study was to compare an alternative method, Colilert-18 Quanti-Tray (ISO 9308-2) with the European bathing water directive (2006/7/EC) reference method, the miniaturised most probable number (MMPN) method (ISO 9308-3), for the analysis of Escherichia coli. Six laboratories analysed a total of 263 bathing water samples in Finland. The comparison was carried out ac...
متن کاملValidation of alternative methods for the analysis of drinking water and their application to Escherichia coli.
In Europe, the Drinking Water Directive of the European Commission indicates which methods (most of which are CEN/ISO-standardized methods) should be used for the analysis of microbiological parameters (European Commission, Environment, Council Directive 98/83/EC of 3 November 1998). According to the Directive, alternative methods "may be used, providing it can be demonstrated that the results ...
متن کاملEvaluation of an Inexpensive Growth Medium for Direct Detection of Escherichia coli in Temperate and Sub-Tropical Waters
The cost and complexity of traditional methods for the detection of faecal indicator bacteria, including E. coli, hinder widespread monitoring of drinking water quality, especially in low-income countries and outside controlled laboratory settings. In these settings the problem is exacerbated by the lack of inexpensive media for the detection of E. coli in drinking water. We developed a new low...
متن کاملA comparison of the International Standards Organisation reference method for the detection of coliforms and Escherichia coli in water with a defined substrate procedure.
AIMS This study investigated the use of the International Standards Organisation (ISO) procedure for the comparison of microbiological methods. Using this procedure the ISO reference procedure for the detection of coliforms and Escherichia coli in water was compared with a defined substrate method (ColilertTM). METHODS AND RESULTS A total of 20 laboratories from 13 European countries compared...
