RESUMO
Background: Kluyvera intermedia is a bacterium indigenous to humans. But Kluyvera intermedia bacteremia has been not reported thus far. We report a case of Kluyvera intermedia bacteremia with septic shock due to left obstructive pyelonephritis as a result of urolithiasis. Case presentation: A 66-year-old woman with septic shock due to left obstructive pyelonephritis was transferred to our hospital. Tazobactam/Piperacillin 4.5 g was administered every 8 h for 5 days. The patient's condition improved, and she was transferred back to the previous hospital. Kluyvera intermedia was obtained by blood cultures. The patient was successfully treated with a two-week course of antibiotics. Conclusions: We describe the first case of bacteremia with septic shock caused by Kluyvera intermedia. Kluyvera intermedia can be a causative pathogen of septic shock. Since this bacterium has not been reported in the past, we expect further reports and the accumulation of cases in the future.
