A Case of Healthcare Associated Pneumonia Caused by Chryseobacterium indologenes in an Immunocompetent Patient

Abstract EN

Chryseobacterium indologenes is nonmotile, oxidase, and indole positive Gram-negative aerobic bacilli which is widely found in plants, soil, foodstuffs, and water.

It can colonize hospital environment due to ability to survive in chlorine-treated water supplies.

Chryseobacteria can also colonize patients via contaminated medical devices such as respirators, intubation tubes, humidifiers, intravascular catheters, and prosthetic valves.

Immune suppression, comorbidities, use of broad-spectrum antibiotics, and extreme age are other important risk factors for Chryseobacterium infections.

We report a case of an 82-year-old male admitted to our hospital with the complaint of altered mental status with history of trauma, and recent orthopedic and neurosurgery operations.

He was transferred to neurosurgery intensive care unit due to respiratory failure.

Urine culture yielded extended spectrum beta lactamase (ESBL) (+).

E.

coli and C.

indologenes were isolated from transtracheal aspirate.

He was treated with ertapenem, and levofloxacin and discharged with full recovery.
