Current Classification The genus Proteus currently consists of five named species (P. mirabilis, P. penneri, P. vulgaris, P. myxofaciens, and P. hauseri) and three unnamed genomospecies (Proteus genomospecies 4, 5, and 6).. Proteus vulgaris is a rod-shaped, nitrate-reducing, indole -positive and catalase -positive, hydrogen sulfide -producing, Gram-negative bacterium that inhabits the intestinal tracts of humans and animals. The genus of Proteus consists of motile, aerobic and facultatively anaerobic, Gram-negative rods.

The objective is to differentiate gram-negative bacilli based on decarboxylation or deamination of lysine and the formation of hydrogen sulfide (H2S). The genus Proteus is classified in the enteric bacteria, together with Escherichia coli, Salmonella, Shigella, Enterobacter and Serratia.All these bacteria are small, Gram-negative rods and are facultative anaerobes: they ferment sugars in anaerobic conditions but can use a wide range of organic molecules in aerobic conditions.
