Discospondylitis is an infectious Intervertebral disc inflammation and adjacent vertebral bodies of the spine in dogs, caused by bacteria or fungi.

The most important facts at a glance

Discospondylitis is an infectious Intervertebral disc inflammation and adjacent vertebral bodies in dogs, caused by microorganisms, mostly bacteria such as Staphylococcus or Escherichia coli. The infection can enter the spine through blood, neighboring foci of infection, or direct penetration. Dogs with weakened immune systems or previous infections are particularly at risk. Symptoms include Back pain, stiff gait, Paralysis, and Fever. Diagnosis requires clinical examinations, X-rays, MRI or CT scans, and blood tests. Treatment involves long-term antibiotic therapy, Pain relievers, and possibly surgical interventions. The prognosis is often favorable with early detection, but severe neurological deficits can impair recovery. Preventive measures are difficult, but good health care and treatment of other infections can reduce the risk. Research focuses on accurate pathogen identification, improved imaging techniques, and new therapeutic approaches, including genetic studies on predisposition. Rehabilitation through physiotherapy can support recovery and improve the quality of life of affected dogs.

Causes

Discospondylitis is a disease that primarily affects the intervertebral discs and adjacent vertebral bodies. It occurs when microorganisms, usually bacteria, enter the bloodstream and settle in the spine. This infection leads to inflammation and can significantly affect the structure of the spine.

The most common pathogens that cause discospondylitis are bacteria such as Staphylococcus spp., Streptococcus spp., and Escherichia coli. Less commonly, fungi such as Aspergillus spp. can also play a role. The infection can reach the intervertebral discs through various routes, such as direct spread from a neighboring site of infection, blood infection (hematogenous spread), or direct penetration during trauma or surgery on the spine.

A weakened immune system can increase the risk of discospondylitis. Infections of the skin, respiratory tract, teeth, or urogenital system can serve as starting points for bacteria to enter the bloodstream and settle in the spine. Surgical procedures or injuries to the spine can also increase the risk of infection.

The disease is more common in medium to large breeds and often affects middle-aged to older dogs. Male dogs are more susceptible than female dogs, and dogs with a history of infections or a weakened immune system have an increased risk.

Symptoms

Rare symptoms:

The symptoms of discospondylitis can vary, depending on the severity and progression of the infection. The most common signs include increasing lameness or Limb weakness, often accompanied by Pain in the spine. This Pain can cause the dog to be unwilling to walk, jump, or climb stairs.

In many cases, the dog shows general weakness, reduced activity, and possibly Fever. The affected dogs may also show loss of appetite and lose weight. In severe cases, neurological deficits can occur if the infection affects the spinal cord or nerve roots. This can manifest as a coordination disorder, an unsteady gait, or even Paralysis.

If the disease is not treated in time, permanent damage to the spine can occur, which can significantly impair the dog’s quality of life.

Diagnosis

The diagnosis of discospondylitis requires a thorough clinical examination, supported by imaging procedures and laboratory tests. A detailed history and physical examination help to narrow down the symptoms and possible causes.

X-rays of the spine are an important part of the diagnosis. They can show changes in the vertebral bodies and intervertebral discs that indicate inflammation. However, in early stages of the disease, the X-rays may be unremarkable. In such cases, magnetic resonance imaging (MRI) or computed tomography (CT) may be required to obtain more detailed images of the spine.

In addition, blood tests can be performed to identify signs of infection or inflammatory conditions. A blood culture can help identify the specific pathogen, especially if a bacterial infection is suspected. In some cases, a biopsy or fine needle aspiration from the affected region may be necessary to confirm the diagnosis and identify the pathogen.

Therapy

Treatment for discospondylitis focuses on eliminating the infection and relieving the pain. Antibiotics are usually administered over a long period, often for several weeks to months, to completely eliminate the infection. The choice of antibiotic depends on the identified pathogen and the results of sensitivity tests.

Pain relievers and anti-inflammatory drugs are used to relieve the pain and inflammation. In some cases, surgical intervention may be necessary, especially if there are severe neurological symptoms or instability of the spine. The surgery may aim to remove infected tissue, stabilize the spine, or relieve pressure on the spinal cord.

Close monitoring and regular follow-up examinations are important to assess the progress of treatment and ensure that the infection is completely eliminated. Physiotherapy can also be helpful to improve mobility and strengthen the muscles.

Prognosis and follow-up care

The prognosis for discospondylitis depends on various factors, including the severity of the infection, the affected spinal region, and the speed of diagnosis and treatment. With early detection and appropriate treatment, the prognosis is often favorable, and many dogs recover completely or show a significant improvement in symptoms.

In cases where there have been severe neurological deficits or significant damage to the spine, the prognosis may be worse. Some dogs may retain permanent neurological deficits despite treatment. Continuous monitoring and aftercare are crucial to prevent relapses and maintain the dog’s quality of life.

Prevention

Prevention of discospondylitis is difficult because the disease is often caused by unpredictable infections. However, good general health care, including regular veterinary check-ups, can help minimize the risk.

Timely treatment of infections and inflammatory conditions of other parts of the body is important to prevent the spread of bacteria into the bloodstream. In dogs with an increased risk, such as those with a weakened immune system, special attention should be paid to hygiene and the prevention of infections.

After surgical procedures on the spine or injuries, attention should be paid to signs of infection, and a veterinarian should be consulted immediately if symptoms occur that could indicate discospondylitis. A balanced diet and regular exercise support general health and can strengthen the immune system, which may reduce the risk of infection.

Outlook on current research

Research on discospondylitis in dogs has made significant progress in recent years. A central aspect is the identification of the pathogens that cause the infection. Bacteria such as Staphylococcus, Streptococcus, and Escherichia coli are common triggers, but fungi can also be involved. Modern diagnostic procedures, including polymerase chain reaction (PCR), help in the accurate identification of these microorganisms. This allows targeted antibiotic therapies to be developed that are more effective and gentler.

Another important area of research concerns imaging techniques for the diagnosis of discospondylitis. Traditional X-rays are often not sufficient to detect early changes. New procedures such as magnetic resonance imaging (MRI) and computed tomography (CT) offer more detailed insights into the structure of the spine and enable earlier diagnosis of the disease. These techniques not only help with diagnosis but also with monitoring the course of the disease and the success of therapy.

The development of new therapeutic approaches is also a focus of research. In addition to antibiotic treatment, the role of anti-inflammatory drugs is being investigated to relieve the Pain and inflammatory conditions associated with the disease. Experimental studies on animal models are intended to test new biological drugs that support the immune system in fighting the infection more effectively.

Another interesting research approach is the genetic predisposition to discospondylitis. Some dog breeds seem to be more susceptible to this disease. Deciphering genetic markers could help to identify at-risk animals early on and take preventive measures in the future. Breeders could use this information to adjust their breeding strategies accordingly.

Finally, rehabilitation after discospondylitis is also being extensively investigated. Physiotherapy and targeted exercise programs can support recovery and improve the quality of life of affected dogs. Studies show that a combination of drug therapy and physical rehabilitation provides the best results. The exploration of optimal rehabilitation strategies is therefore of great interest in order to maximize the mobility and well-being of the animals.
