This is a bit tricky. Both Proteus vulgaris and Pseudomonas aeruginosa are Gram-negative and rod-shaped. According to Bergey's Manual of Systematic Bacteriology, Proteus vulgaris tests positive for sulfur reduction, urease production, tryptophan deaminase production, and indole production. Pseudomonas aeruginosa reduces sulfur and nitrate, and has a characteristic green color. The API 20E Identification System is a test strip that can be used to identify Proteus vulgaris versus other bacteria.

An even easier way to test this is the gelatinase test.

Or, slant the bacteria on a Triple Sugar Iron slant or place them in a SIM agar deep. P. vulgaris tests positive for Hydrogen Sulfide production, changing the media to a black color around the organism, while P. aeruginosa does not produce Hydrogen Sulfide.

What is Proteus vulgaris on the Blood Hemolysis Test?

Proteus vulgaris is a bacterium that shows beta hemolysis on blood agar plates. In the Blood Hemolysis Test, this means that Proteus vulgaris will cause complete lysis of red blood cells, resulting in a clear zone around the bacterial growth on the agar plate.

Is Proteus Vulgaris acid-fast?

No, Proteus vulgaris is not acid-fast. Acid-fast bacteria retain the primary stain, carbol fuchsin, despite exposure to acid-alcohol decolorizer, while non-acid-fast bacteria do not retain the stain. Proteus vulgaris is a non-acid-fast bacterium.


What are the IMViC and TSI results for Proteus vulgaris?

IMViC results for Proteus vulgaris are typically indole negative, methyl red positive, Voges-Proskauer negative, and citrate positive. TSI results for Proteus vulgaris show alkaline/alkaline (red/red) slant/butt with no gas production and no hydrogen sulfide production.
