Application of 16S rRNA Gene Sequencing To IdentifyBordetella hinzii as the Causative Agent of Fatal Septicemia

摘要

We report on the first case of fatal septicemia caused byBordetella hinzii. The causative organism exhibited a biochemical profile identical to that of Bordetella aviumwith three commercial identification systems (API 20E, API 20 NE, and Vitek GNI+ card). However, its cellular fatty acid profile was not typical for either B. avium or previously reported strains of B. hinzii. Presumptive identification of the patient's isolate was accomplished by traditional biochemical testing, and definitive identification was achieved by 16S rRNA gene sequence analysis. Phenotypic features useful in distinguishing B. hinzii from B. avium were production of alkali from malonate and resistance to several antimicrobial agents.
