Auritidibacter ignavus in ear discharge of paediatric patients: Two cases reports and literature review

Introduction

The development and research of new technologies for identifying microorganisms, has allowed the identification of hitherto unknown bacteria. Auritidibacter ignavus is a newly described Gram-positive rod possibly associated with otitis, although its role as an etiologic agent in otitis is currently controversial.

Methods

We report two cases of recurrent otitis in paediatric patients in which A. ignavus was isolated and review the previous cases reported in the literature.

Results

All the isolates were identified as A. ignavus by proteomic and genomic methods. Both patients recovered from their symptoms.

Conclusion

A. ignavus was recovered from ear discharges of paedriatic patients with chronic ear problems. All the cases previously reported in the literature were adults. More evidence is needed for the association between A. ignavus and otitis, since data regarding this species are still scarce.
