Infection primarily occurs from these reservoirs. In hospital settings, it is not unusual for gram-negative bacilli to colonize both the skin and oral mucosa of both patients and hospital personnel. Proteus is also found in multiple environmental habitats, including long-term care facilities and hospitals. 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 organisms are implicated as serious causes of infections in humans, along with Escherichia, Klebsiella, Enterobacter, and Serratia species. P mirabilis and P vulgaris account for most clinical Proteus isolates. The genus is currently composed of Proteus mirabilis, Proteus vulgaris, Proteus penneri, Proteus hauseri, Proteus terrae, and Proteus cibarius. The first isolates were reported and characterized by Hauser in the late 19th century. Proteus species are part of the Enterobacteriaceae family of gram-negative bacilli.
