Flavobacterium is a genus of Gram-negative, nonmotile and motile, rod-shaped bacteria that consists of 130 recognized species. [1] [2] Flavobacteria are found in soil and fresh water in a variety of environments. Several species are known to cause disease in freshwater fish. [3]
Flavobacterium psychrophilum causes the bacterial cold water disease on salmonids and the rainbow trout fry disease on rainbow trout. F. columnare causes the cotton-wool disease on freshwater fishes. F. branchiophilum causes the bacterial gill disease on trout. Another member of this genus, F. okeanokoites is the original source for the type IIs restriction endonuclease FokI, used in Zinc finger nucleases and TALENs. [4]
Species who are a part of the genus Flavobacterium are most likely found scattered along in nature. These microbes are mostly found in aquatic ecosystems and wet areas with freshwater or seawater.

The Chlamydiota are a bacterial phylum and class whose members are remarkably diverse, including pathogens of humans and animals, symbionts of ubiquitous protozoa, and marine sediment forms not yet well understood. All of the Chlamydiota that humans have known about for many decades are obligate intracellular bacteria; in 2020 many additional Chlamydiota were discovered in ocean-floor environments, and it is not yet known whether they all have hosts. Historically it was believed that all Chlamydiota had a peptidoglycan-free cell wall, but studies in the 2010s demonstrated a detectable presence of peptidoglycan, as well as other important proteins.
Elizabethkingia meningoseptica is a Gram-negative, rod-shaped bacterium widely distributed in nature. It may be normally present in fish and frogs; it may be isolated from chronic infectious states, as in the sputum of cystic fibrosis patients. In 1959, American bacteriologist Elizabeth O. King was studying unclassified bacteria associated with pediatric meningitis at the Centers for Disease Control and Prevention in Atlanta, when she isolated an organism that she named Flavobacterium meningosepticum. In 1994, it was reclassified in the genus Chryseobacterium and renamed Chryseobacterium meningosepticum(chryseos = "golden" in Greek, so Chryseobacterium means a golden/yellow rod similar to Flavobacterium). In 2005, a 16S rRNA phylogenetic tree of Chryseobacteria showed that C. meningosepticum along with C. miricola were close to each other but outside the tree of the rest of the Chryseobacteria and were then placed in a new genus Elizabethkingia named after the original discoverer of F. meningosepticum.
Mycobacteroides chelonae is a species of bacteria from the phylum Actinomycetota belonging to the genus Mycobacteroides. Mycobacteroides chelonae is a rapidly growing mycobacterium that is found all throughout the environment, including sewage and tap water. It can occasionally cause opportunistic infections of humans. It is grouped in Runyon group IV.
Enteric redmouth disease, or simply redmouth disease is a bacterial infection of freshwater and marine fish caused by the pathogen Yersinia ruckeri. It is primarily found in rainbow trout and other cultured salmonids. The disease is characterized by subcutaneous hemorrhaging of the mouth, fins, and eyes. It is most commonly seen in fish farms with poor water quality. Redmouth disease was first discovered in Idaho rainbow trout in the 1950s. The disease does not infect humans.
The class Flavobacteriia is composed of a single class of environmental bacteria. It contains the family Flavobacteriaceae, which is the largest family in the phylum Bacteroidota. This class is widely distributed in soil, fresh, and seawater habitats. The name is often spelt Flavobacteria, but was officially named Flavobacteriia in 2012.
Alteromonas is a genus of Pseudomonadota found in sea water, either in the open ocean or in the coast. It is Gram-negative. Its cells are curved rods with a single polar flagellum.
Flavobacterium columnare is a thin Gram-negative rod bacterium of the genus Flavobacterium. The name derives from the way in which the organism grows in rhizoid columnar formations.
Columnaris (also referred to as cottonmouth) is a symptom of disease in fish which results from an infection caused by the Gram-negative, aerobic, rod-shaped bacterium Flavobacterium columnare. It was previously known as Bacillus columnaris, Chondrococcus columnaris, Cytophaga columnaris and Flexibacter columnaris. The bacteria are ubiquitous in fresh water, and cultured fish reared in ponds or raceways are the primary concern – with disease most prevalent in air temperatures above 12–14 °C. It is often mistaken for a fungal infection. The disease is highly contagious and the outcome is often fatal. It is not zoonotic.
Streptococcus iniae is a species of Gram-positive, sphere-shaped bacterium belonging to the genus Streptococcus. Since its isolation from an Amazon freshwater dolphin in the 1970s, S. iniae has emerged as a leading fish pathogen in aquaculture operations worldwide, resulting in over US$100M in annual losses. Since its discovery, S. iniae infections have been reported in at least 27 species of cultured or wild fish from around the world. Freshwater and saltwater fish including tilapia, red drum, hybrid striped bass, and rainbow trout are among those susceptible to infection by S. iniae. Infections in fish manifest as meningoencephalitis, skin lesions, and septicemia.
Chryseobacterium is a genus of Gram-negative bacteria. Chryseobacterium species are chemoorganotrophic, rod shape gram-negative bacteria. Chryseobacterium form typical yellow-orange color colonies due to flexirubin-type pigment. The genus contains more than 100 described species from diverse habitats, including freshwater sources, soil, marine fish, and human hosts.
Cytophaga is a genus of Gram-negative, gliding, rod-shaped bacteria. This bacterium is commonly found in soil, rapidly digests crystalline cellulose C. hutchinsonii is able to use its gliding motility to move quickly over surfaces. Although the mechanism for this is not known, there is a belief that the flagellum is not used
Bacterial taxonomy is subfield of taxonomy devoted to the classification of bacteria specimens into taxonomic ranks.
Bacterial cold water disease (BCWD) is a bacterial disease of freshwater fish, specifically salmonid fish. It is caused by the bacterium Flavobacterium psychrophilum, a psychrophilic, gram-negative rod-shaped bacterium of the family Flavobacteriaceae. This bacterium is found in fresh waters with the optimal growth temperature below 13 °C, and it can be seen in any area with water temperatures consistently below 15 °C. Salmon are the most commonly affected species. This disease is not zoonotic.
Yersinia ruckeri is a species of Gram-negative bacteria, known for causing enteric redmouth disease in some species of fish. Strain 2396-61 is its type strain.
Vagococcus salmoninarum is a species of bacteria, with type strain NCFB 2777. It is pathogenic towards Oncorhynchus mykiss.
Flavobacterium psychrophilum is a psychrophilic, gram-negative bacterial rod, belonging to the Bacteroidota. It is the causative agent of bacterial coldwater disease (BCWD) and was first isolated in 1948 during a die-off in the salmonid Oncorhynchus kisutch.
Trueperella pyogenes is a species of nonmotile, facultatively anaerobic, Gram-positive bacteria. The cells typically measure 0.5 by 2.0 μm. They appear as pleomorphic or coccoid rods. They tend to be grouped singly or in short chains but are sometimes grouped into V-shaped pairs.
Elizabeth Osborne King was an American microbiologist who discovered and described bacteria of medical importance at the United States Centers for Disease Control and Prevention from the late 1940s through the early 1960s. A 1984 CDC manual dedication referred to King as "internationally known as an authority on a variety of unusual bacteria." The genera Kingella and Elizabethkingia and several species of bacteria are named to honor her for her pioneering work. King died of cancer on April 8, 1966, in Atlanta, where she is interred in Oakland Cemetery.
Tenacibaculum is a Gram-negative and motile bacterial genus from the family of Flavobacteriaceae.
Flavobacterium branchiarum is a bacterium from the genus of Flavobacterium which can cause bacterial gill disease in rainbow trouts.
