Also found in: Acronyms.

Fu·so·bac·te·ri·um nu·cle·a·'tum

a bacterial species (probably Plaut or Vincent bacillus) found in the mouth and in infections of the upper respiratory tract, pleural cavity, and occasionally the lower intestinal tract; it is the most common cause of human fusobacterium infection, and is the type species of the genus Fusobacterium.

Fu·so·bac·te·ri·um nu·cle·a·tum

(fū'zō-bak-tēr'ē-ŭm nū-klē-ā'tŭm)
A species that is found indigenously in gingival crevices; involved in infections of the upper respiratory tract and pleural cavity.
Synonym(s): Vincent bacillus.


a genus of anaerobic non-spore-forming, gram-negative bacteria found as normal flora in the mouth and large bowel, and often in necrotic tissue, probably as secondary invaders.

Fusobacterium equinum
contributes to necrotizing pneumonia and pleurisy in horses.
Fusobacterium necrophorum
found in abscesses of the liver, lungs and other tissues and in chronic ulcer of the colon. A common major participant in bovine footrot, calf diphtheria, ruminal necrobacillosis, hepatic abscesses and thrush in horses. Synergistic with Dichelobacter nodosus in ovine footrot. Divided into subspecies necrophorum, formerly biotype A, which is especially found in liver abscesses of cattle, and subspecies funduliforme, formerly biotype B, which is particularly found in ruminal abscesses and in ruminal contents.
Fusobacterium nodosus
Fusobacterium nucleatum
isolated from cat and dog bite wounds.
Fusobacterium russii
isolated from cat and dog bite wounds.
