Flavobacteria
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. Flavobacteriia are gram-negative aerobic rods, 2–5 μm long, 0.1–0.5 μm wide, with rounded or tapered ends. They form circular cream to orange coloured colonies on agar, and are typically simple to successfully culture. Flavobacteriia is a chemoorganotroph and are known for their ability to mineralize or degrade dissolved organic matter of high molecular weight and particulate plant material. Flavobacteriia have impacts on both the environment and human society, as they are able to cause diseases in many organisms. They are important in the decomposition of organic matter and pollutants, and are key members in the formation of marin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flavobacteriales
The order Flavobacteriales comprises several families of environmental bacteria. Comparative genomics and molecular signatures ''Flavobacteriales'' is of one of the orders from the phylum ''Bacteroidota''. Comparative genomic studies have identified several conserved indels, as well as 27 proteins that are uniquely shared by different sequenced Flavobacteriales and Bacteroidota species supporting this inference. Additionally, these studies have also identified 38 proteins that seem to be specific for the species from the order ''Flavobacteriales''. Of these proteins, 26 were present in all sequenced species, while the remaining 12 were missing in only one or two species. These signature proteins provide potential molecular markers for this order. Several proteins have also been identified which are unique to the ''Flavobacteriales'' and '' Bacteroidales'' orders, indicating the species from these two orders shared a common ancestor exclusive of other ''Bacteroidota''.

Flavobacteriaceae
Flavobacteriaceae is a family of rod-shaped gram negative bacteria. The family contains many environmental bacteria, with some species being potential pathogens. History The family of ''Flavobacteriaceae'' was first proposed by Reichenbach in 1989, it was approved by the IJSEM in 1992. The description of the family was emended several times in 1996 and 2002. In 2020, the family was split, with several genera moved to the newly established family of '' Weeksellaceae''. Biology Species of the ''Flavobacteriaceae'' are predominantly rod-shaped and stain gram-negative. Many species in the ''Flavobacteriaceae'' are motile, with most non-motile species formerly placed in the family now being placed in the '' Weeksellaceae''. Most species are aerobic, while some are microaerobic to anaerobic; for example '' Capnocytophaga'' and '' Coenonia''. Several members of the family are considered halophilic or psychrotolerant. The predominant respiratory quinone is menaquinone-6. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bacteroidota
The phylum (biology), phylum Bacteroidota (synonym Bacteroidetes) is composed of three large classes of Gram-negative bacteria, Gram-negative, nonsporeforming, anaerobic or aerobic, and rod-shaped bacteria that are widely distributed in the environment, including in soil, sediments, and sea water, as well as in the guts and on the skin of animals. Although some ''Bacteroides'' spp. can be Opportunistic Pathogens, opportunistic pathogens, many ''Bacteroidota'' are Symbiotic bacteria, symbiotic species highly adjusted to the gastrointestinal tract. ''Bacteroides'' are highly abundant in intestines, reaching up to 1011 cells g−1 of intestinal material. They perform metabolic conversions that are essential for the host, such as degradation of proteins or complex sugar polymers. ''Bacteroidota'' colonize the gastrointestinal tract already in infants, as non-digestible Human milk oligosaccharide, oligosaccharides in mother milk support the growth of both ''Bacteroides'' and ''Bifidoba ...

Flavobacterium
''Flavobacterium'' is a genus of Gram-negative, nonmotile and motile, rod-shaped bacteria that consists of 130 recognized species. Flavobacteria are found in soil and fresh water in a variety of environments. Several species are known to cause disease in freshwater fish. '' 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 A restriction enzyme, restriction endonuclease, REase, ENase or'' restrictase '' is an enzyme that cleaves DNA into fragments at or near specific recognition sites within molecules known as restriction sites.

Columnaris
Columnaris (also referred to as cottonmouth and saddle-back disease) is a 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. Due to the appearance of bacterial clumps, it can be mistaken for a fungal infection. The disease is highly contagious, and the outcome is commonly fatal. It is not zoonotic. Causes Columnaris disease occurs in both wild and farmed freshwater fish and is caused by the bacteria ''F. columnare''. The age of an infected fish impacts the course of the infection. The bacteria usually enter fish through gills, mouth, or small wounds, and is prevalent where high b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
