ABSTRACT:
A test device provides an enclosed culture device for safe determination of the presence of a targeted microorganism. A test chamber is concentrically received within a culture chamber, and caps allow selective opening of one chamber without opening the other. A window in the test chamber allows selective flow of liquid between chambers, the window being so placed as to require particular manipulation of the chambers. The test chamber contains a culture medium and, through appropriate manipulation, a sample in the culture chamber is caused to wet the culture medium. The device is then incubated, and the sample in the culture chamber maintains high humidity in the test chamber because of the window. A pre-treatment vial is also provided so the sample can be treated before being placed into the culture chamber, to eliminate interfering organisms or the like.
