Fusobacteriaceae

Fusobacteriaceae is a family of anaerobic bacteria that are part of the Fusobacteriales order. This family includes several genera, the most notable of which is Fusobacterium. Members of the Fusobacteriaceae family are known for their role in various human diseases, including periodontal diseases, Lemierre's syndrome, and more.

Taxonomy

The Fusobacteriaceae family is part of the Fusobacteriales order, which belongs to the Fusobacteria phylum. This family includes several genera, such as Fusobacterium, Ilyobacter, Propionigenium, and Psychrilyobacter. The Fusobacterium genus is the most well-known and studied among these.

Characteristics

Fusobacteriaceae are Gram-negative bacteria that are obligate anaerobes. They are non-spore-forming and can be either rod-shaped or spindle-shaped. Some species are motile, while others are not. They are known for their ability to produce butyric acid and other short-chain fatty acids.

Pathogenicity

Members of the Fusobacteriaceae family are often found in the human mouth and gut, where they are part of the normal microbiota. However, they can also cause various diseases. For example, Fusobacterium nucleatum is associated with periodontal diseases, while Fusobacterium necrophorum can cause Lemierre's syndrome, a rare but serious condition.

Treatment and Prevention

Treatment of infections caused by Fusobacteriaceae typically involves antibiotics. However, some strains have shown resistance to certain antibiotics, making treatment more challenging. Prevention strategies include maintaining good oral hygiene to prevent periodontal diseases caused by Fusobacterium nucleatum.
