Infection caused by Cupriavidus gilardii in a convalescent COVID-19 patient

Abstract

Cupriavidus gilardii is an aerobic, gram-negative bacillus that can opportunistically infect immunocompromised patients or those undergoing invasive procedures. We reported a case caused by C. gilardii in a previously basic healthy 78-year-old male, who had COVID-19 and had used corticosteroids recently. The bacterium was identified as C. gilardii by the metagenomic next-generation sequencing from the patient's bronchoalveolar lavage fluid and blood. In addition, this is the first time that we isolated C. gilardii from bronchoalveolar lavage fluid, which provides clinical experience in rare bacterial infections.
