Flavobacteriia

The class Flavobacteriia is composed of a single order of environmental bacteria.[1] According to Bernardet et al., Flavobacteriia are Gram-negative aerobic rods, 2–5 μm long, 0.3–0.5 μm 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 fresh and seawater habitats.[2] In particular, Flavobacteriia are prominent members of marine biofilms.[3] The type species Flavobacterium aquatile was isolated from a well in Kent, England.[4]

Flavobacteriales

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.

The name is often spelled Flavobacteria, but officially named Flavobacteriia in 2012.[5][6]
