Comamonas testosteroni, previously known as Pseudomonas testosteroni, is an aerobic, motile, nonspore-forming Gram-negative bacterium. It rarely infects humans and can commonly live in environments, such as soil, water, plants, and animals. In addition to this, it can also survive for a long period in hospital environments. The microorganism infections are often treatable in humans; thus, mortality is rare. Up to today, among all cases in the literature, only five died due to underlying diseases. We present a case of a 10-year-old male patient with cerebral palsy who was positive with C. testosteroni in the tracheal aspirate culture. The patient died on day 50 of hospitalization owing to the fact that his prognosis was extremely poor. In the medical literature, the patient is the second case of pneumonia.
