Eikenella corrodens causing deep-seated infections. Six-year experience in a University Hospital in Madrid

Introduction: Eikenella corrodens (EC) is part of the normal microbiota of the oropharynx and a recognised opportunistic pathogen. It is mainly involved in head and neck infections, but it has also been identified as a cause of pleuropulmonary and intraabdominal infections. Its identification could be difficult due to its fastidious growth requirements, especially in the context of polymicrobial infection and is probably underreported.

Methods: We carried out a retrospective 5-year review of clinical charts and laboratory database.

Results: We describe the clinical and microbiological characteristics of 9 deep-seated infections caused by EC, diagnosed in locations different from the head and neck.

Conclusion: EC deep-seated infections are often found in patients with comorbid conditions and a history of interventional procedures. Due to the characteristic torpid evolution of EC abscesses, imaging to assess the necessity of debridement and avoid early cessation of antibiotics is necessary.
