First Case of Cupravidus paculus Infection in a Lung Transplant Recipient: A Case Report.

Cupravidus paculus is a rare Gram-negative bacterium that can cause a wide range of severe infections, largely in immunocompromised patients. It is a ubiquitous organism found in natural and man-made environments and in the hospital. Herein, we present the first case of C. paculus infection in a lung transplant recipient, which required prolonged antibiotic therapy to achieve complete clearance. Additionally, we review the existing literature on the clinical and microbiological profile of C. paculus, along with previously documented cases of clinical infections. Our case highlights the potential sources of C. paculus infections, the importance of appropriate disinfection protocols for medical devices, and the need for antibiotic sensitivities to guide treatment.
