Coloured scanning electron micrograph (SEM) of Proteus vulgaris is a rod-shaped, Gram-negative bacterium that inhabits the intestinal tracts of animals and humans and can be pathogenic. P. vulgaris forms a natural part of the intestinal flora in animals and humans, and is also found in soil and water. In people whose immune systems are suppressed it can be an opportunistic pathogen, causing urinary tract infection, pneumonia or septicaemia. Unlike its relative Proteus mirabilis, P. vulgaris is not sensitive to ampicillin and cephalosporins. Proteus vulgaris is a chemoheterotroph in the Proteobacteria group.
