Picture from http://www.denniskunkel.com. Life History: Proteus mirabilis is part of the normal flora of the human gastrointestinal tract. It can also be found free living in water and soil.When this organism, however, enters the urinary tract, wounds, or the lungs it can become pathogenic.roteus mirabilis is part of the normal flora of the gastrointestinal tract, and as a result the bacteria enters the urinary tract or infects medical equipment by the fecal route. Consequently, prevention includes good sanitation and hygiene, including proper sterilization of medical equipment.
