The system for the detection and identification of the pathogens, comprises at least two separate culture media, separated from each other, in one container. Each of these contains a different sugar and a pH indicator and optionally means for detecting oxidase activity. Sugars may be replaced by tryptophan, tyrosine or phenylalanine. The identification is made on the basis of fermentation of the sugars or on color formation for the tryptophan etc.
