A Case of a Persistent Postoperative Infection Caused by Multidrug-ResistantKluyvera ascorbatain the Oral and Maxillofacial Region

Abstract

Introduction.Kluyvera ascorbatainfection is rare, but it has been extensively studied because of its potential to cause a wide range of infections and its ability to transfer the gene encoding for CTX-M-type extended spectrumβ-lactamases (ESBLs) to other Enterobacteriaceae.Case Presentation. The authors report a case of a 61-year-old Chinese male with a persistent postoperative infection caused by a multidrug-resistant ESBL-producingK. ascorbata. Following antimicrobial susceptibility testing, he was aggressively treated with gentamicin and levofloxacin with a favorable outcome.Conclusion. To our knowledge, this is the first case report of a persistent postoperative infection caused by a multidrug-resistantK. ascorbatain the oral and maxillofacial region. The authors suggest thatK. ascorbatainfection warrants prompt identification and aggressive antibiotic management, given that ESBL-producingK. ascorbatais resistant to penicillins and first-generation to third-generation cephalosporins.
