Discospondylitis associated with three unreported bacteria in the dog

Three cases of discospondylitis in the dog, caused respectively by Pseudomonas aeruginosa, Enterococcus faecalis and Staphylococcus epidermidis, are reported. These bacteria have not previously been documented as being the cause of the condition in this species. The neurological involvement was severe in all three cases. Two dogs were paraplegic and one was tetraplegic, and one of the paraplegic dogs had no deep pain on the extremities of both pelvic limbs. All dogs were treated surgically with a satisfactory neurological recovery.
