Fusobacteria / Fusobacteriia / Fusobacteriales / Leptotrichiaceae / Leptotrichia

Straight or slightly curved rods, 0.5–3.0 × 5–15 µm, with one or both ends pointed or rounded. Frequently arranged in pairs, separate filaments, or chains, often with flattened ends. No club formation or branching. Nonmotile. Non-spore-forming. Gram-stain-negative or Gram-stain-variable. Anaerobic on first isolation; many strains subsequently grow aerobically in the presence of CO₂ . Optimum temperature 35–37°C. Good growth occurs at pH 7.0–7.4. Chemoorganotrophic. Metabolize carbohydrates with formation of acid without gas. The major product of glucose fermentation is lactic acid. Acetic and succinic acids may be produced in trace amounts. Hydrogen sulfide and indole are not produced. Nitrate is not reduced. The primary habitat is the oral cavity of humans and some animals.

DNA G+C content (mol%): 29.2–31.6.

Type species: Leptotrichia buccalis (Robin 1853) Trevisan 1879, 147^AL (Leptothrix buccalis Robin 1853, 345).
