ABSTRACT:
A device for culturing microorganisms is described comprising a body member comprising a self-supporting, water-proof substrate; a layer of adhesive coated on the substrate, the adhesive being non-inhibitory to the growth of microorganisms; and a cold-water-soluble powder adhered uniformly to the surface of the adhesive, the powder comprising a gelling agent and/or nutrients for growing microorganisms. Another device is described comprising a body member comprising a self-supporting, water-proof substrate; a coating coated directly on the substrate, the coating being substantially water-free and consisting essentially of a cold-water-reconstitutable material comprising a gelling agent and/or nutrients for growing microorganisms; and a cover sheet releasably adhered to the bottom member, the cover sheet being substantially impermeable to bacteria and water vapor. The devices are activated by the addition of water or an aqueous test sample.
