Providencia stuartii

Description and Significance

Providencia stuartii is a gram-negative bacteria. . In laboratory settings, ,it is best cultured in Nutrient Agar or Columbia agar, with growth best at 37C and a mesophilic temperature range. It is of risk group 2 on the biosafety level[4].

P. stuartii has a straight rod morphology and is typically 0.6-0.8 micrometers by 1.5-2.5 micrometers in size (2016 Hardy Diagnostics), see Figure 3.

P. stuartii is ubiquitous, being commonly found in water, soil, and animal reservoirs.

It is responsible for many UTIs in patients under long term catheterization and has a high degree of antibiotic resistance, a major concern for hospitals and nursing homes where many patients are vulnerable to infection from this microbe. Treatment, once infected, is difficult.

Genome Structure

Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence?


Cell Structure, Metabolism and Life Cycle

Interesting features of cell structure; how it gains energy; what important molecules it produces.


Ecology and Pathogenesis

Habitat; symbiosis; biogeochemical significance; contributions to environment.
If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
