urease test

urease test
a test for urea based on the conversion of urea into ammonium carbonate by the urease of soybean. 2. (for the production of urease by bacteria) urease test broth (see under culture medium) is prepared in slants. After inoculation of the surface and incubation, urease-positive cultures produce an alkaline reaction (red color) in the medium. Proteus cultures show an early urease-positive reaction; other bacteria (such as Salmonella and Shigella) usually have a delayed response.
