Chryseobacterium is a genus of Gram negative,nonmotile,oxidase- and indole-positive aerobic bacilli .
normally found in plants, soil, foodstuffs, and fresh and marine water sources.
It can survive in chlorine-treated water supplies, which can lead to reservoirs for hospital-acquired infections.
Chryseobacterium indologenes was first isolated from the tracheal aspirate of a patient with ventilator-associated pneumonia in 1993.
