First case report of sepsis caused by in Japan.

INTRODUCTION

Species of the genus are opportunistic, usually saprophytic, glucose-non-fermenting, Gram-negative bacilli found in agricultural soil. infections are the least common infections and have low incidence.

CASE PRESENTATION

Herein, we report the first case of sepsis with in Japan in a 67-year-old Japanese woman with a history of hyperlipidaemia, hypertension, diabetes, hypothyroidism and osteoporosis. She had undergone cerebrovascular treatment because she was diagnosed with a subarachnoid haemorrhage. The results of postoperative blood culture showed oxidase-positive, urease-positive, non-lactose-fermenting Gram-stain-negative rods. Using the Vitek2 system, the isolate was distinctly identified as . However, 16S rRNA gene sequencing showed 99.93 % similarity with the type strain of and 99.06 % similarity with the type strain of . Additional gene sequencing analysis using (97.2 %) and (96.2 %) also showed that the isolated strain is most closely related to . The patient was cured by treatment using intravenous meropenem (3 g/d) for 4 weeks and was discharged safely.

CONCLUSION

The definite source of sepsis was unknown. However, the possibility of having been infected through the catheter during the cerebrovascular operation was speculated.
