Fusobacteriaceae

The Fusobacteriaceae are a family of Gram-negative bacteria within the phylum Fusobacteriota. Members of this family are known for their spindle-shaped morphology and are often associated with various human infections.

Characteristics

Fusobacteriaceae are anaerobic, non-spore-forming bacteria. They are typically rod-shaped and can be found in the human oral cavity, gastrointestinal tract, and other mucosal surfaces. These bacteria are known for their ability to produce butyric acid as a metabolic byproduct.

Pathogenicity

Members of the Fusobacteriaceae family, particularly the genus Fusobacterium, are associated with several human diseases. They are implicated in periodontal diseases, Lemierre's syndrome, and other systemic infections. Fusobacterium necrophorum is a notable pathogen within this family.

Genus Fusobacterium

The genus Fusobacterium is the most well-known within the Fusobacteriaceae family. It includes species such as Fusobacterium nucleatum and Fusobacterium necrophorum, which are significant in both human and veterinary medicine.

Ecology

Fusobacteriaceae are commonly found in the oral cavity and are part of the normal flora. However, they can become opportunistic pathogens under certain conditions, leading to infections in various parts of the body.

Clinical Significance

The presence of Fusobacteriaceae in clinical specimens can indicate an anaerobic infection. These bacteria are often resistant to many common antibiotics, making infections challenging to treat. Proper identification and sensitivity testing are crucial for effective management.
