The Flavobacteriaceae are a family of bacteria. The type genus is Flavobacterium .
features
The gram test is negative. The cells are rod-shaped. Some species can form filamentous cells. They are short or moderately elongated. Some form helical cells. There are immobile or slidingly movable species.
Some species are obligatorily aerobic and also obligatorily anaerobic . Colonies often have a yellow color, formed by the pigment flexirubin , hence the name (flavus = Latin yellow). Some representatives are cold-loving ( psychrophil ), examples are Flavobacterium psychrophilum , the cause of columnar disease in fish, as well as types of Polaribacter and Psychroflexus .
Pathogenicity
There are only a few pathogenic (disease-causing) species in the Flavobacteriaceae family . Most species are free in the environment. The pathogenic representatives include z. B. Bergeyella zoohelcum , Myroides odoratus and Myroides odartimismus and Chryseobacterium indolgens . Others are also pathogenic to some animal species. Thus causing Flavobacterium branchiophilum the bacterial gill disease of trout . Elizabethkingia meningoseptica (formerly known as Flavobacterium meningoseptica ) can cause meningitis in young children and infants.
Occurrence
Species of the Flavobacteriaceae occur in the soil and in fresh water, brackish water or in sea water. Some have been found in food and milk. Some, as yet unidentified members of the family inhabit the digestive tract of insects , others live within cells (intracellularly) of amoeba. Many species of the genus Capnocytophaga occur in the mouths of humans, some also in the mouths of dogs and cats.
