Cupriavidus Pauculus as A Cause of Late Onset Post-Operative Sinusitis

Cupriavidus pauculus is an environmental gram-negative bacilli of low virulence, being increasingly reported to be associated with invasive infections in immunocompromised patients and device related infections. Often undetected or misidentified in most microbiology laboratories, identification of this organism requires increased suspicion and automated identification or molecular methods. We hereby describe a curious case of post-operative acute sinusitis caused by this rare yet emerging human pathogen.
