14 Μαΐ 2024 · E. coli infection is diagnosed when the bacteria are identified from the sample of a patient with an acute diarrheal illness. Testing for STEC Stool samples should be routinely cultured for E. coli O157 and simultaneously assayed for non-O157 STEC with a test that detects Shiga toxins (or the genes that encode them).
detection of E. coli and/or related bacteria termed “coliforms” (1). Many different techniques can be used to detect the presence of these indicator microorganisms.
Before starting. The broths for both methods in this procedure change color when the test result is positive. The P/A Broth with MUG fluoresces under a UV light when E. coli is in the sample culture. Set the temperature of the incubator to 35 ± 0.5 °C (95 ± 0.9 °F). Let the incubator temperature become stable, then add the samples.
Detection Limit. The detection limit for this analysis is 1 Most Probable Number (MPN) per 100mL of sample. Scope of the test method. This standard operating procedure describes the test method for the collection and analysis of water samples for the enumeration of Escherichia coli (E. coli) and Total coliform bacteria.
