FlavobacteriiaRANK: ClassTAXONOMY: cellular organisms -> Bacteria -> Bacteroidetes/Chlorobi group -> Bacteroidetes -> Flavobacteriia OVERVIEW: The class 'Flavobacteriia' is composed of a single order of environmental bacteria.Bergey's Manual of Systematic Bacteriology, 2nd ed., vol. 1 (The Archaea and the deeply branching and phototrophic Bacteria) (D.R. Boone and R.W. Castenholz, eds.), Springer-Verlag, New York (2001). pp. 465- 466. Flavobacteriia are a group of commensal bacteria and opportunistic pathogens. Flavobacterium psychrophilum causes the septicemic diseases rainbow trout fry syndrome and bacterial cold water disease. According to Bernardet et al., Flavobacteriia are gram-negative aerobic rods, 2–5 mcm long, 0.3–0.5 mcm wide, with rounded or tapered ends that are motile by gliding, yellow (cream to orange) colonies on agar, decompose several polysaccharides but not cellulose, G+C contents of 32–37 %, and are widely distributed in soil and freshwater habitats. The type species is F. aquatile. The name is often spelled Flavobacteria, but officially named Flavobacteriia in 2012.
