Title: MICROBIAL DETECTION DEVICES AND METHODS OF USING THE SAME
Abstract:
Devices for microbial detection of microorganisms are provided including a body member including a substrate having a first major surface and a second major surface. The device further includes a first adhesive composition adhered to a portion of the first major surface. A number of particles of a substantially dry first microbial growth nutrient composition are distributed in the first adhesive composition, and a cold-water-soluble first hydrogel-forming composition is adhered to the first adhesive composition. The device also includes a cover sheet attached to the body member, where the cover sheet includes a first major surface facing the body member. Devices including a water-proof pouch, further comprising a porous membrane filter are also provided. Methods for detecting and enumerating at least one microorganism in a sample using the devices are additionally provided.
