1. A thin film culture plate device for identifying and enumerating staphylococci in a sample containing more than one species of bacteria, comprising:

  • i) a self-supporting, waterproof substrate to which is adhered a rehydratable selective medium powder containing nutrients, inhibitors to promote the growth of staphylococci, and at least one gelling agent, andii) a transparent cover sheet having a layer of adhesive consisting essentially of a dual substrate system having an indolylglucopyranoside substrate which provides a visible first color change in the presence of beta-glucosidase and a phosphate substrate which provides a visible second color change in the presence of staphylococci and at least one gelling agent.
