Fusobacterium necrophorum is a gram-negative, rod-shaped, anaerobic bacterium that is a primary or secondary etiological agent in a variety of necrotic purulent infections in animals and humans. Included are diseases of cattle such as liver abscesses and foot rot, which have economically important consequences for the cattle industry. The major virulence factor of this bacterium is leukotoxin, ...

Hyperbaric oxygen exposures were evaluated for treatment of progressive liver abscesses produced by intraperitoneal injection of combined cultures of Fusobacterium necrophorum plus either Bacteroides fragilis subsp. fragilis or Fusobacterium nucleatum in a mouse model. Infected control and hyperbaric oxygen-exposed mice were autopsied 5 or 6 weeks after inoculation of bacteria and were assigned...
