| Abstract |
Herein we describe a rare case of sepsis in Japan caused by Herbaspirillum seropedicae. The patient was a Japanese woman in her 80s. She was referred to our hospital for evaluation of an acute exacerbation of interstitial pneumonia. Blood cultures obtained on admission revealed Gram-negative curved bacilli, which were identified as H. seropedicae based on 16S rRNA gene analysis. Herbaspirillum spp. can be misidentified as Burkholderia cepacia complex or Ralstonia pickettii using biochemical tests. However, the characteristic curved body morphology, susceptibility to β-lactams and resistance to colistin, and genetic analysis allowed identification. If a glucose non-fermentative bacterium which is curved body morphology and susceptible to most antimicrobial agents is detected in a cancer or immunosuppressed patient, it may belong to Herbaspirillum spp., so care should be taken in identifying it using biochemical tests. |
