Agrobacterium radiobacter (CDC Group Vd-3)

An aerobic, oxidase-positive, gram-negative bacillus that produces nonpigmented to light beige colonies. Some colonies may be mucoid due to the production of a slime capsule by the organism. It is isolated from plants and soil. It is primarily a plant pathogen. It has been isolated from clinical specimens but is rarely reported as the cause of human infections.
