What is Discospondylitis (Spondylitis)?

Discospondylitis, also spelled as diskospondylitis, is an infection of the vertebrae and the surrounding cartilaginous discs. It is also referred to as vertebral osteomyelitis and the swelling created by this disease can cause severe pain as well as nerve damage in afflicted dogs if left untreated. If your pet is displaying the symptoms of this kind of disorder, don’t hesitate to contact a veterinary professional. Timely intervention will help to prevent permanent damage to the compressed nerves and to the bone surrounding the spinal cord.

Discospondylitis is the swelling of the vertebrae and the disks that surround them, as caused by either a bacterial or fungal infection.

Symptoms of Discospondylitis (Spondylitis) in Dogs

The pressure that is put on the spinal cord due to swelling of the vertebrae and discs can cause a variety of symptoms, including:

  • Abdominal pain
  • Back pain or stiffness
  • Collapse
  • Depression
  • Fever
  • Hunched back
  • Lack of coordination
  • Lameness
  • Loss of appetite
  • Neck pain or stiffness
  • Paralysis in one or more limbs
  • Poor reflexes
  • Reluctance to rise
  • Shaking
  • Staggering
  • Tremors
  • Weakness
  • Weight loss
  • Yelping unexpectedly when touched or moving

Types

Discospondylitis (diskospondylitis) is an infection of the vertebrae and the discs that provide cushioning between the bones of the spine. If only the vertebrae are included in the infection, and the discs are spared, then it is known simply as spondylitis. 

There are a number of bacteria and fungi that can cause the infection that causes discospondylitis or spondylitis. These can include:

Bacteria

  • Brucella canis
  • Clostridium perfringens
  • Erysipelothrix rhusiopathiae
  • Escherichia coli
  • Pasteurella canis
  • Proteus spp
  • Pseudomonas aeruginosa
  • Staphylococcus aureus, Staphylococcus intermedius
  • Streptococcus spp

Fungi

  • Aspergillus terreus
  • Paecilomyces variotii
  • Scedosporium apiospermum

Causes of Discospondylitis (Spondylitis) in Dogs

Several circumstances can increase the risk of this disorder developing. Previous infections such as UTI’s, abscesses, and contaminated wounds can move to the spinal column during treatment and proliferate unseen. Traumatic injuries that involve damage or fracturing of the bone can make it easier for the bacteria to invade the skeletal structure. Other conditions, such as chronic dental disease or post-operative complications, can influence the chances of this type of infection occurring. German Shepherd and Great Dane breeds are more likely to develop discospondylitis than other breeds.

Diagnosis of Discospondylitis (Spondylitis) in Dogs

There are a few disorders with very similar symptoms, such as intervertebral disk disease (IVDD), that this condition will need to be differentiated from. A physical examination will help your pet’s doctor to evaluate the general health of your dog and will also assist her in pinpointing the location of the pain. Preliminary blood tests, such as a complete blood count and biochemistry profile, will be done to determine if there are any infections or imbalances present. An electromyogram can be used to determine the electrical activity of the muscles, and a spinal tap may be done as well to get a sample of cerebrospinal fluid. 

In most cases, the analysis of the fluid will reveal both that there is an infection, and which bacterium or fungus is causing the inflammation. Radiograph (x-ray) imaging will be used to help visualize the location and extent of the disease, and a neurological examination may be done as well. In many cases, a contrast dye will be injected into the space around the spinal cord to better see the fluid’s movement within the spine during the x-ray procedure.

Treatment of Discospondylitis (Spondylitis) in Dogs

The medication will vary somewhat depending on what diagnosis is reached. Bacterial infections will be treated with antibiotics, while antifungals will be utilized to defeat fungal infections. The treatment time for infections that affect the bone is considerably greater than other infections. A course of antibiotics or antifungals for this type of infection will usually take at least six weeks and may take up to six months. Anti-inflammatory medications will also be required to both manage pain and reduce pressure on the spinal cord itself. In critical cases, surgical intervention may be needed to debride deep wounds or to lessen the compression on the spinal cord. Exercise restriction will most likely be recommended until the swelling has been significantly reduced to prevent further damage to the spine. Your dog will need to have periodic x-rays to monitor the progress of the spine until both the infection and the swelling have been eliminated.

Recovery of Discospondylitis (Spondylitis) in Dogs

Some improvement may be noticeable in as little as two weeks, but it is important to ensure that your dog continues treatment until your dog’s doctor tells you it is safe to stop giving the medications. Discospondylitis is difficult to treat due to its location and as with other stubborn bacterial and fungal infections, early cessation of the prescriptions may result in the reoccurrence of the infection. Osteoarthritis often remains in the area of the infection, even after the infection is eliminated, and should be managed with appropriate pain relievers. 

Although the prognosis for dogs with bacterial infection is good with timely treatment, the prognosis is generally more guarded for dogs who contract a fungal infection instead.

Hello, Our American bulldog had spinal surgery in July for a spinal fracture. Shortly after surgery he developed disco spondylitics, and was on antibiotics for 14 weeks. He just had a 2nd follow up x-ray last week and the surgeon said it looked clear and took him off antibiotics. My question is does this infection lie dormant? I'm just a little scared since we don't have that medicine keeping the infection at bay now.

Long term antibiotic treatment is usually the treatment of choice and is curative in mild and moderate conditions; dormant infections are rare especially after a long course of antibiotics. It is important to keep a close eye on Sarge and if you do notice any symptoms you should visit your Veterinarian immediately. Regards Dr Callum Turner DVM

I would recommend you take Apollo into see your Veterinarian as German Shepherds are prone to some issues involving the spine which should be checked as a dog ages. Without examining Apollo and taking some x-rays I cannot say what the specific cause is; until you visit your Veterinarian it is important to give Apollo as much rest as possible.
