Colonies of Chryseobacterium indologenes on Mueller-Hinton agar. Cultivation 72 hours, aerobic atmosphere, 28°C. C. indologenes is inherently resistant to tetracycline.
Colonies of Chryseobacterium indologenes are deep yellow due to the production of the water-insoluble pigment flexirubin. The natural habitats of Chryseobacterium are soil, plants, foodstuff, and water sources, including those in hospitals. It rarely has clinical significance.
C.indologenes has been documented to cause bacteremia in hospitalized patients with severe underlying disease. Nosocomial infections due to C.indologenes have been linked to the use of indwelling devices during the hospital stay.
