Abstract

Achromobacter species are non-fermenting, Gram-negative bacilli. While Achromobacter xylosoxidans is known to be an opportunistic pathogen, little is known about infection due to A. xylosoxidans in pregnant women. We herein on report a case of bacteremia caused by A. xylosoxidans in a pregnant woman.

A 35-year-old pregnant Japanese woman was admitted due to urgent premature delivery. The patient developed urosepsis on day 36 following admission and was delivered by emergency caesarean section. Two sets of blood cultures were grown and were positive for A. xylosoxidans. The patient recovered immediately after treatment with a tazobactam/piperacillin regimen. However, the patient reported sudden severe right lower back pain on day 43 following admission. An enhanced abdominal CT showed active bleeding of a right renal angiomyolipoma (AML), for which we performed an arterial embolization. Based on antimicrobial susceptibilities, A. xylosoxidans bacteremia was treated with tazobactam/piperacillin for 14 days, during which the patient's clinical symptoms improved.

Our case suggests that A. xylosoxidans could be a causative pathogen of bacteremia in pregnant women and it is presumed that it is caused by urinary tract or catheter-related bloodstream infection.
