ABSTRACT:
Disc assay devices and methods for the detection and enumeration of microorganisms are disclosed. The devices and methods include a plurality of discs attached to a substrate and a reflector on one surface of each of the discs to reflect electromagnetic energy of selected wavelengths after the energy has passed through the disc. The reflector may be useful to improve the accuracy of detection and/or enumeration of target microorganisms on the assay devices. A system for detecting and/or enumerating target microorganisms on disc assay devices is also provided.
