Abstract
The invention relates to a method for detecting and/or identifying Escherichia coli (E. coli) in a biological sample, that comprises inoculating the biological sample liable to contain E. coli on a detection medium that comprises tryptophan and a substrate for an enzyme A, expressed by the majority of E. coli, in order to obtain bacterial colonies; detecting the colonies expressing the activity of the enzyme A and identifying them as being E. coli; and detecting the colonies that do not express the activity of the enzyme A, carrying out an indole test, and identifying the colonies having a positive indole test as being E. coli.
