[Empyema necessitatis caused by Campylobacterrectus. Rapid identification by MALDI-TOF MS]

Abstract

Empyema necessitatis (EN) is a very rare complication of a pleural empyema, in which the infection extends to adjacent soft tissues. Anaerobic bacteria are very rare etiologic agents of EN, which occurs in the course of chronic infections. We present the first case of empyema necessitatis caused by Campylobacter rectus. Bacterial identification was carried out by mass spectrometry (MALDI-TOF MS) and antimicrobial susceptibility was determined by the epsilometer method.
