Abstract
BackgroundRaoultella planticola, a Gram-negative, aerobic bacillus commonly isolated from soil and water, rarely causes invasive infections in humans. Septic shock from R. planticola after burn injury has not been previously reported.Case presentationA 79-year-old male was admitted to the emergency intensive care unit after extensive flame burn injury. He accidently caught fire while burning trash and plunged into a nearby tank filled with contaminated rainwater to extinguish the fire. The patient developed septic shock on day 10. The blood culture detected R. planticola, which was identified using the VITEK-2 biochemical identification system. Although appropriate antibiotic treatment was continued, the patient died on day 12.ConclusionsClinicians should be aware of fatal infections in patients with burn injury complicated by exposure to contaminated water.

Summary
Raoultella planticola is a Gram-negative, aerobic bacillus commonly found in soil and aquatic environments [1]. We report a case of fatal septic shock due to R. planticola bacteremia following flame burn injury complicated by exposure to contaminated water to extinguish the fire. Case presentation A 79-year-old male was referred to our tertiary hospital after extensive flame burn injury. Piperacillin/tazobactam was replaced by 1 g doses of meropenem three times daily for concerning antibiotic resistance on day 10; the patient’s condition continued to deteriorate. His blood culture was positive for R. planticola, which was identified using the VITEK-2 biochemical identification system. Repetitive burn wound cultures yielded P. aeruginosa, which was sensitive to both piperacillin/tazobactam and meropenem with minimum inhibitory concentration (MIC) of ≦ 2 μg/mL and.
