title: [A modified MacConkey medium].
abstract: We used MacConkey Agar(MCA) medium powder as a basis and added 6-benzoy-2-naphthyl phosphate disodium salt to modify MCA medium. This method was identified by examining several kinds of enteric pathogenic bacteria. Thus it allows us to observe lactose fermentative and phosphatase reaction simultaneously and to recognize Enterobacteriaceae from non-fermentable bacteria on primary culture plates according to the color of colony. This improved method simplifies the recognition procedure and shortens the time so that it is helpful to correctly choosing identification kit.
