Possible synonym: Flavobacterium devorans.
Gram-negative rods, 0.3-0.8 / 1.0-1.9 µm. Motile by means of polar monotrichous
flagellum, only when rhamnose was added as a carbon source in the liquid medium.
Yellow-pigmented colonies. Strictly aerobic, optimal growth temperature 30 ºC. Can
grow on: Trypticase Soy Agar ± 5% sheep blood, Nutrient agar, Mueller-Hinton agar.
Isolated from soil, water, plants & clinical specimens.
Nosocomial infections in humans and animals (bacteremia, urinary tract infections, pneumonia, endophtalmitis & wound infections).
