Abstract
Upper airway infections caused by anaerobic bacteria, including pharyngitis and tonsillitis, are a common cause of septic thrombosis (Lemierre's syndrome). Although otitis media rarely progresses to systemic infection, an abscess surrounding the middle ear can affect the central nervous system. Trueperella bernardiae was originally considered a non-pathogenic aerobic bacterium but has subsequently been reported to cause bacteremia and brain abscesses. Here, we report a case of otitis media caused by T. bernardiae complicated by meningitis, subdural empyema, and septic pulmonary emboli in an immunocompetent patient.

Matsuhisa Y, Kenzaka T, Kobayashi S, Taguchi J, Hirose H, Gotoh T. Sepsis following acute pyelonephritis caused by Trueperella bernardiae: a case report and literature review. BMC Infect Dis 2023; 23:121. [PMID: 36829134 PMCID: PMC9960629 DOI: 10.1186/s12879-023-08080-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Accepted: 02/13/2023] [Indexed: 02/26/2023] Open
Abstract
BACKGROUND Trueperella bernardiae is a coryneform, gram-positive bacterium that is a commensal of the skin and upper respiratory tract. It is treated as a contaminant and rarely causes infections. Blood, urine, and abscesses have been previously reported as the most common sites of infection. Infections caused by T. bernardiae are rarely reported in bedridden very old patients with reduced activities of daily living (ADL). In this report, we describe a case of sepsis due to acute pyelonephritis caused by T. bernardiae in a very old patient with impaired ADL. CASE PRESENTATION A 94-year-old woman had a home visit from her local physician. She was bedridden and used diapers. On the day of admission, she presented with fever and dyspnea and was admitted with a diagnosis of sepsis associated with acute pyelonephritis. T. bernardiae was detected in blood and urine cultures; furthermore, multiple bacteria were detected in a urine culture. She was treated with ampicillin/sulbactam 3 g every 12 h on the day of admission. The fever was controlled, and inhaled oxygen 1 L/min via a nasal cannula was administered for dyspnea until hospitalization day 2. On hospitalization day 2, her fever resolved to 36 °C. Antimicrobials were de-escalated and changed to cephazolin and then to cephalexin on hospitalization days 9 and 16, respectively, and were continued until day 22. On hospitalization day 28, the urinary tract infection flared up; however, her fever resolved by hospitalization day 38 after the re-administration of antimicrobial agents. She was discharged on hospitalization day 60. CONCLUSIONS We encountered a rare case of sepsis following acute pyelonephritis caused by T. bernardiae infection. When bedridden, diaper-using, very old patients present with urinary tract infections caused by multiple bacteria, the presence of rare opportunistic organisms, such as T. bernardiae, should be considered.
