Bacteremia due to Providencia stuartii: review of 49 episodes.

We reviewed cases of Providencia stuartii bacteremia at a large community teaching hospital during a 12-year period (1981 to 1992). None of the infections were hospital-acquired. Of the 49 patients, 47 (96%) came from a nursing home, and 45 (92%) had a long-term indwelling Foley catheter. The urinary tract was definitely proven to be the source of bacteremia in 35 patients (71%) and was the probable source in another 5 patients (11%). Polymicrobial bacteremia occurred in 25 patients (51%). The overall mortality rate during hospitalization was 25%.
