Culture medium devices and systems are shown and described. In one embodiment, the device comprises a culture medium adapted for test fluid inoculation without the concerns associated with a spreading step. In particular examples, a printed grid on the outer surface of a culture device is visible on the inner surface for colony counting after a test has been developed. The result is a device that allows for detection, identification, and transportation of various microorganisms without preparation or spreading steps, and more particularly to a culture medium in which a test fluid inoculated thereto diffuses rapidly.

Culture medium method and device

Phages can be detected as rapid indicators of the hygienic quality of a sample. Both continuous flow methods and devices, single sample methods and devices, of various volumes, can be used. Single samples may be tested by single or multi-step testing methods. Test kits can be provided in easy-to-use formats. Certain phages, such as coliphage, are useful as indicators of fecal contamination.
