Abstract

Bordetella hinzii is a nonfermenting, gram-negative rod and a rare opportunistic pathogen that can cause respiratory infections, bacteremia, and cholangitis. Here, we report the first case of bacteremia caused by B. hinzii in Korea. A 59-year-old man was admitted for the biopsy of a mass lesion in the left lower lobe, which was detected during a health screening. The blood cultures collected from the patient with high fever (> 39℃), which developed 4 hours after the biopsy, yielded gram-negative rods. The gram-negative bacilli were identified as B. hinzii using matrix-assisted laser desorption ionization time-of-flight mass spectrometry and PCR sequencing of the 16S rRNA gene. After 9 days of antimicrobial treatment with ampicillin/sulbactam, piperacillin/tazobactam, or meropenem, the patient improved and was discharged.
