Where is Proteus found in the body?
(Struble 2013) Proteus species are most commonly found in the human intestinal tract as part of normal human intestinal flora, along with Escherichia coli and Klebsiella species, of which E coli is the predominant resident. Proteus is also found in multiple environmental habitats, including long-term care facilities and hospitals.
What is the urease test for Proteus vulgaris?
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 will still identify it with a negative urease test. When inoculated in a gelatin stab test, P. vulgaris is capable of hydrolysis of gelatin. P. mirabilis causes 9% of Proteus infections.
