Fusobacteriota

Fusobacteriota is a phylum of bacteria. They are obligate anaerobes, and are common inhabitants of the oral cavity, gastrointestinal tract, and vagina. They are implicated in a variety of diseases, including periodontal diseases, Lemierre's syndrome, and appendicitis.

Taxonomy

The phylum Fusobacteriota was previously known as Fusobacteria. It contains two classes: Fusobacteriia and Leptotrichiia. The class Fusobacteriia contains the order Fusobacteriales, which includes the families Fusobacteriaceae and Leptotrichiaceae. The class Leptotrichiia contains the order Leptotrichiales, which includes the family Leptotrichiaceae.

Characteristics

Fusobacteriota are Gram-negative, non-spore-forming, non-motile rods. They are obligate anaerobes, meaning they can only survive in environments without oxygen. They are capable of fermentation, and produce butyric acid and acetic acid as byproducts.

Pathogenicity

Fusobacteriota are implicated in a variety of diseases. They are a common cause of periodontal diseases, and are also associated with Lemierre's syndrome, a rare disease characterized by thrombophlebitis of the internal jugular vein and septicemia. They have also been found in cases of appendicitis, and are thought to play a role in the development of the disease.

Treatment

Treatment of infections caused by Fusobacteriota typically involves antibiotics. However, some strains of Fusobacteriota have been found to be resistant to certain antibiotics, making treatment more difficult.
