A modification of Christensen's medium by Maslen this medium is generally used to detect rapid urease activity of Proteus spp. It can also be used to detect urease activity of other Enterobacteriaceae including urease-producing Salmonella spp. and Shigella spp.
When used for the latter purpose it is necessary to increase the incubation time to as long as 48 hours. The peptone provides the required nitrogen, carbon and vitamins. Glucose is a fermentable carbohydrate. The potassium dihydrogen phosphate is a buffer and sodium chloride maintains an osmotic balance. Phenol red is a pH indicator.
