Abstract

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.

Highlights

Chryseobacterium indologenes formally known as Flavobacterium indologenes is nonmotile, oxidase, and indole positive Gram-negative aerobic bacilli
Though Chryseobacterium species are infrequent human pathogen, it can be identified as causative agent in patients with pneumonia [5], bacteremia [6], sepsis [7], urinary tract infection [8], peritonitis [9], and ocular infection [10]
Patients with long-term indwelling devices and prolonged exposure to broad-spectrum antibiotics are at high risk for Chryseobacterium indologenes infections

Summary

Introduction

Chryseobacterium indologenes formally known as Flavobacterium indologenes is nonmotile, oxidase, and indole positive Gram-negative aerobic bacilli. It is widely found in plants, soil, foodstuffs, and water [1]. It has ability to survive in chlorine-treated municipal water supplies and can colonize sink basins and taps. It can colonize hospital environment and can be a potential source for healthcare associated infections (HAIs) [2]. Patients with long-term indwelling devices and prolonged exposure to broad-spectrum antibiotics are at high risk for Chryseobacterium indologenes infections. Increased use of colistin and tigecycline against multidrug resistant bacteria such as Acinetobacter baumannii is associated with increased prevalence of Chryseobacterium infections in intensive care units [11]
