How is the urease test useful for identifying members of the genus proteus?
Urease, which is produced by some microorganisms, is an enzyme that is especially helpful in the identification of Proteus vulgaris. Although other organisms may produce urease, their action on the substrate tends to be slower than that seen with Proteus species. Therefore, this test serves to rapidly distinguish members of this genus from other non-lactose-fermenting enteric microorganisms.
