FIG. 1. Urea agar test results. Urea agar slants were inoculated as follows: (a) uninoculated, (b)Proteus mirabilis (rapidly urease positive), (c) Klebsiella pneumoniae (delayed urease positive), (d)Escherichia coli (urease negative). All samples were incubated at 37 oC for 16 hours. Stuart’s Urea Broth (4, 5)
10 sie 2022 · Quality Control of Urease Test. Positive: Proteus vulgaris (ATCC13315) Weak positive: Klebsiella pneumoniae (ATCC13883) Negative: Escherichia coli (ATCC25922) Limitations of Urease Test. Some organisms rapidly split urea (Brucella and H. pylori), while others react slowly.
Klebsiella pneumoniae is urea positive (blue color of the slope), metabolise glucose with production of gas (bubbles under a piece of glass - in detail left down side of each plate) and is lactose positive (but on Endo agar its colonies often remain quite pale).
