P. stuartii |
Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]
Overview
Providencia is a Gram negative, motile bacterium of the family Enterobacteriaceae. Some strains (P. stuartii, for example) are opportunistic pathogens in humans and can cause urinary tract infections, particularly in patients with long-term indwelling urinary catheters or extensive severe burns. Other strains (for example P. burhodogranariea and P. sneebia) are found in the haemolymph of Drosophila melanogaster fruit flies.
Some strains are sensitive to ampicillin.

- Note (1): Duration of treatment for (UTI) is 7 days common or 3-5 days after defervescence or control/elimination of complicating factors (e.g.,removal of foreign material catheter).
- Note (2): Duration of treatment for (bacteremia) is 10-14 days or 3-5 days after defervescence or control/elimination of complicating factors
- Note (3): Duration for acute prostatitis (2 weeks), shorter than chronic prostatitis (4-6 weeks)
