/*Proteus vulgaris*/ is a rod-shaped, nitrate-reducing, indole+ and
catalase-positive, hydrogen sulfide-producing, Gram-negative bacterium that
inhabits the intestinal tracts of humans and animals. It can be found in
soil, water, and fecal matter. It is grouped with the Enterobacteriaceae
and is an opportunistic pathogen of humans. It is known to cause wound
infections and other species of its genera are known to cause urinary tract

The term Proteus signifies changeability of form, as personified in the
Homeric poems in Proteus, "the old man of the sea", who tends the
sealflocks of Poseidon and has the gift of endless transformation. The
first use of the term “Proteus” in bacteriological nomenclature
was made by Hauser (1885), who described under this term three types of
organisms which he isolated from putrefied meat. One of the three species
Hauser identified was /Proteus vulgaris/, so this organism has a long
history in microbiology.

Over the past two decades, the genus /Proteus/, and in particular /P.
vulgaris/, has undergone a number of major taxonomic revisions. In 1982,
/P. vulgaris/ was separated into three biogroups on the basis of indole
production. Biogroup one was indole negative and represented a new species,
/P. penneri/, while biogroups two and three remained together as /P.
