Fusobacterium - Wikipedia
Fusobacterium is a genus of obligate anaerobic, Gram-negative, [2] non-sporeforming bacteria [3] belonging to Gracilicutes. Individual cells are slender, rod-shaped bacilli with pointed ends. [4] [5] Fusobacterium was discovered in 1900 by Courmont and Cade and …
Fusobacterium - an overview | ScienceDirect Topics
Fusobacterium spp. can be somewhat variable in their Gram stain and display a range of cellular morphologies from coccoid, pleomorphic spherules (Fusobacterium necrophorum) to rod shaped. Rods can be short with rounded ends or long and thin with pointed ends (F. nucleatum), arrayed end to end (Fig. 249-1C).
Anaerobic Gram-Negative Bacilli - Medical Microbiology - NCBI Bookshelf
Even direct Gram stain may be helpful because of the frequently unique morphology of Gram-negative anaerobic bacilli. In general, these organisms are pale staining and they may stain erratically. Fusobacterium cells may exhibit classic tapered ends and filamentous forms, with or without swollen areas and large round bodies.

The Genus Fusobacterium - SpringerLink
The genus Fusobacterium includes several species of obligately anaerobic, nonsporeforming, motile or nonmotile, Gram-negative rods. Some are slender, spindle-shaped bacilli, while others are pleomorphic rods with parallel sides and rounded ends.
