Providencia stuartii (commonly P. stuartii), is a Gram negative bacterium that is commonly found in soil, water, and sewage. P. stuartii is the most common of the 5 species found in the genus Providencia, with Providencia rettgeri, Providencia alcalifaciens, Providencia rustigianii, P heimbachae.[1] Providencia stuartii can be incubated at 37°C in nutrient agar or nutrient broth.[2] P. stuartii is the genomic source for the restriction endonuclease, PstI.

Role in diseases[edit]

Providencia stuartii is the most common Providencia species capable of causing human infections. Providencia stuartii is an opportunistic pathogen seen in patients with severe burns or long-term indwelling urinary catheters.[2] This puts elderly individuals at a greater risk for P. stuartii infections.[1] In animals P. stuartii infections can cause neonatal diarrhea due to P. stuartii infection in dairy cows. In humans, P. stuartii can be isolated from urine (most common), stool, and blood, as well as from sputum, skin, and wound cultures. P. stuartii septicemia is primarily of urinary origin. It is the most common cause of purple urine bag syndrome.[3] Upon physical examination, P stuartii bloodstream infection is associated with fever, tachycardia, and hypotension.[1]
