Abstract: Enterococcus faecium (E. faecium ) is one of the core components of enterococci and causes serious illnesses in the elderly and immunocompromised patients. Due to its adaptive traits and antibiotic resistance, E. faecium has evolved as a worldwide hospital-associated pathogen, especially vancomsycin-resistant Enterococcus faecium (VREfm). Pneumonia caused by VREfm is quite rare in clinical settings, and optimal treatment has not yet been determined. Here, we present a case of nosocomial VREfm pneumonia with lung cavitation following adenovirus infection, which was successfully treated with linezolid and contezolid.
Keywords: vancomycin-resistant enterococcus, Enterococcus faecium , pneumonia, contezolid
