Multiresistent Cupriavidus pauculus infection in an immunocompromised elderly patient.

Cupriavidus pauculus is a gram-negative bacillus aerobic bacteria widely distributed in nature that can cause, in rare cases, serious infections both in immunocompromised and immunocompetent patients. We describe a case of an elderly patient admitted in emergency room with septic shock and diagnosed with a urinary tract infection. During his hospital stay, his clinical and analytical conditions have deteriorated. Blood cultures were positive for C. pauculus only sensitive to minocycline. Despite every effort, due to multiple comorbidities and a nosocomial pneumonia, the patient ends up dying.
