Escherichia hermanniias the sole cause of osteomyelitis in a patient with an open tibial shaft fracture

Abstract

Escherichia hermannii is a rare monomicrobial cause of infection in humans. E. hermannii has never before been reported as the sole isolate from an infected open tibia fracture. We present a case of E. hermannii infection after a type III open tibia fracture. The patient was initially treated with irrigation and debridement, open reduction internal fixation and primary wound closure. However, after 8 weeks, he developed a draining wound and infection at the fracture site. He required a repeat debridement, hardware removal, external fixation and 6 weeks of intravenous ceftriaxone for treatment. At 2-year follow-up, he remains infection free, asymptomatic and continues to work with excellent functional outcomes. This case adds to the growing literature that evidences E. hermannii as an organism that can be pathogenic, virulent and cause monomicrobial infection.

Draft genome sequence of an Atlantibacter hermannii clinical strain isolated from human muscle tissue

“…Escherichia hermannii has been transferred to this genus as Atlantibacter hermannii ( 1 ). A. hermannii has been implicated as a human pathogen in several cases ( 2 – 4 ). Here, we describe the genome sequence of an A. hermannii clinical strain.…”

Catheter-Related Bloodstream Infection in Hemodialysis Patient due to <i>Atlantibacter hermannii</i>

“…hermannii was initially considered non-pathogenic bacteria. According to the recent literature, it has been reported as a human pathogen in cases of bloodstream infections (BSIs), urinary tract infections, purulent conjunctivitis, osteomyelitis, and cephalohematoma [2][3][4][5]. Several reports testify that the most frequently infected patients are immunosuppressed, especially those undergoing hemodialysis [6,7].…”
