Causes

Discospondylitis is a disease that primarily affects the intervertebral discs and adjacent vertebral bodies. It occurs when microorganisms, usually bacteriaBacteria are microscopic, single-celled organisms that exist in almost every environment on Earth. Some types of bacteria are beneficial or even essential to life, while others can cause disease., enter the bloodstream and settle in the spine. This infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease. leads to inflammation and can significantly affect the structure of the spine.

The most common pathogens that cause discospondylitis are bacteriaBacteria are microscopic, single-celled organisms that exist in almost every environment on Earth. Some types of bacteria are beneficial or even essential to life, while others can cause disease. such as Staphylococcus spp., Streptococcus spp., and Escherichia coli. Less commonly, fungi such as Aspergillus spp. can also play a role. The infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease. can reach the intervertebral discs through various routes, such as direct spread from a neighboring site of infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease., blood infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease.

Paralysis can be caused by injuries, illnesses, or disorders of the nervous system..

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 diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. of discospondylitis requires a thorough clinical examination, supported by imaging procedures and laboratory tests. A detailed historyThe medical history is the systematic collection of a patient's medical history through questioning. It includes information about previous illnesses, treatments, allergies, and lifestyle habits. and physical examination help to narrow down the symptoms and possible causes.

X-rays of the spine are an important part of the diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients.. 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)Magnetic resonance imaging is an imaging technique that uses strong magnetic fields and radio waves to create detailed images of the inside of the body. It is used in veterinary medicine to diagnose diseases of the brain, spine, and other organs. or computed tomography (CT)Computed tomography (CT) is an imaging technique that uses X-rays and computer technology to create cross-sectional images of the body. It enables a detailed view of bones, organs, and other structures and is used for the diagnosis of injuries, diseases, and for planning medical interventions. may be required to obtain more detailed images of the spine.

In addition, blood tests can be performed to identify signs of infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease. or inflammatory conditions. A blood culture can help identify the specific pathogenA pathogen is a microorganism or virus that can cause disease in its host.

It can provide information on how a disease is expected to develop. 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

PreventionPrevention includes measures taken to prevent diseases or injuries. In veterinary medicine, this includes vaccinations, parasite control, and health monitoring. 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.

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 infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease.. BacteriaBacteria are microscopic, single-celled organisms that exist in almost every environment on Earth. Some types of bacteria are beneficial or even essential to life, while others can cause disease. 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 diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. of discospondylitis. Traditional X-rays are often not sufficient to detect early changes. New procedures such as magnetic resonance imaging (MRI)Magnetic resonance imaging is an imaging technique that uses strong magnetic fields and radio waves to create detailed images of the inside of the body. It is used in veterinary medicine to diagnose diseases of the brain, spine, and other organs. and computed tomography (CT)Computed tomography (CT) is an imaging technique that uses X-rays and computer technology to create cross-sectional images of the body. It enables a detailed view of bones, organs, and other structures and is used for the diagnosis of injuries, diseases, and for planning medical interventions. offer more detailed insights into the structure of the spine and enable earlier diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. of the disease. These techniques not only help with diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. but also with monitoring the course of the disease and the success of therapyTherapy refers to the treatment of diseases or disorders with the aim of alleviating symptoms, promoting healing, or improving quality of life. Therapies can be medicinal, surgical, or through other medical interventions..

The development of new therapeutic approaches is also a focus of research. In addition to antibiotic treatment, the role of anti-inflammatory drugsAnti-inflammatory drugs are medications that reduce inflammation. They can be divided into nonsteroidal anti-inflammatory drugs (NSAIDs) and corticosteroids and are used in dogs and cats to reduce Inflammatory conditions and Pain. 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 systemThe immune system is the body's defense system against infectious agents such as bacteria, viruses, fungi, and parasites. It comprises a complex network of organs, cells, and molecules that work together to protect the body. in fighting the infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease. more effectively.

Another interesting research approach is the genetic predispositionA predisposition is an innate inclination or susceptibility of an organism to certain diseases or conditions. In dogs and cats, there may be a genetic predisposition to certain conditions such as hip dysplasia or certain heart diseases. 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. PhysiotherapyVeterinary physiotherapy encompasses a range of treatment methods aimed at improving the mobility and well-being of animals through exercise, massage, and other manual techniques. and targeted exercise programs can support recovery and improve the quality of life of affected dogs. Studies show that a combination of drug therapyTherapy refers to the treatment of diseases or disorders with the aim of alleviating symptoms, promoting healing, or improving quality of life. Therapies can be medicinal, surgical, or through other medical interventions. 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.
