Leptotrichia buccalis is an anaerobic, Gram-negative rod bacteria. It is a constituent of normal oral flora.

Morphology

Leptotrichia species are typically large, fusiform-shaped, non-sporulating, and non-motile rods.

Pathology

Almost every case of severe infection with Leptotrichia buccalis reported in medical literature occurred in patients with neutropenia.
