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.

Preferred regimen : Ciprofloxacin 500-750mg PO q12h or 400 mg IV q8-12h OR Levofloxacin 500mg IV/PO q24h OR Piperacillin-Tazobactam 3.375 mg IV q6h OR Ceftriaxone 1-2g IV q24h (donot use if ESBL suspected or critically ill)OR Meropenem 1g IV q8h (consider if critically ill or ESBL suspected)ORAmikacin 7.5mg/kg IV q12h

OR Gentamicin OR Tobramycin acceptable if susceptible but many species are resistant.

Note (1) : Duration of treatment for (UTI)is 7days common or 3-5days after defervescence or control/elimination of complicating factors (e.g.,removal of foreign material catheter).
Note (2) : Duration of treatment for (bacteremia)is 10-14days or 3-5days after defervescence or control/elimination of complicatingfactors.
Note (3) : Duration for acute prostatitis(2weeks), shorter than chronic prostatitis(4-6wks)
Alternative regimen : TMP-SMX(Bactrim)DS1 PO q12h for 10-14days OR TMP 5-10 mg/kg/day IV q6h.
