Klebsiella aerogenes, [2] previously known as Enterobacter aerogenes, is a Gram-negative, oxidase-negative, catalase-positive, citrate-positive, indole-negative, rod-shaped bacterium. [3]
All combine for a Biocode ID of 31406, (Biocode ID 31402, 31404, 31407 all resulting in P. vulgaris with asymptomatic results) for use in the Interpretation Guide/Computer Coding and Identification System. P. vulgaris can also test urease negative in solid media (such as in Enterotube), but will be urease positive in liquid media. The CCIS code ...
In addition, it is indole test-positive, meaning that this organism can split tryptophan to indole, pyruvate, and ammonia. M. morganii also produces urease, allowing it to break down urea. [9] Methyl red tests positive in M. morganii, an indicator dye that turns red due to the bacterium's acid production during fermentation. [7]
Urease activity was first identified in 1876 by Frédéric Alphonse Musculus as a soluble ferment. [4] In 1926, James B. Sumner, showed that urease is a protein by examining its crystallized form. [5]

Rapid urease test, also known as the CLO test (Campylobacter-like organism test), is a rapid diagnostic test for diagnosis of Helicobacter pylori. [1] The basis of the test is the ability of H. pylori to secrete the urease enzyme, which catalyzes the conversion of urea to ammonia and carbon dioxide .
