Immune-deficiency Diseases In Dogs: Find Out What Your Pet May Be Suffering!

 

Diseases that compromise the immune system can have devastating effects and frequently weaken the body’s natural defenses against infection.

Some are caused by genetic predisposition, whereas others are brought on by cancer or viral infections.

 

Deficiencies in Phagocytosis.


Phagocytosis is an important component of the immune system’s overall mechanism.

Phagocytes are cells that can phagocytose, digest, and ultimately kill foreign pathogens that have invaded the body.

Phagocytes are an integral component of the immediate (innate) immune response that the body mounts in response to infections.

They could also play a vital role in the adaptive immune system by presenting antigens to other cells that are members of the adaptive immune system, informing those cells of the existence of the foreign invaders.

This function of the adaptive immune system is called “antigen presentation.”

Phagocytes are formed in the bone marrow, then travel through the bloodstream to various parts of the body, where they eventually congregate in either the tissue or the blood.

Within the body’s tissues, they can be found in the skin and mucous membranes, the spleen and lymph nodes, the coverings of the brain and spinal cord, the bone marrow, and near blood arteries in various parts of the body.

A phagocytosis deficiency can be caused by a low quantity of phagocytes in the blood or by a fault in their capacity to work correctly.

Both of these factors can contribute to the condition. Both congenital (present at birth) and acquired forms are possible (caused by diseases or drugs).

Because of the deficit, an individual is at a greater risk of contracting bacterial infections of the skin, respiratory system, and gastrointestinal tract.

Antibiotics are not very effective against these infections.

 

Leukocytes Adhesion Deficiency.


A lack of a necessary receptor on white blood cells causes a condition known as leukocyte adhesion deficiency.

This stops the white blood cells responsible for protecting the body against infections from leaving the bloodstream.

Dogs afflicted with this condition experience recurrent bouts of severe bacterial infections and delayed wound healing.

The disease has been identified in Irish Setters and is also found in people.

Complement Deficiency.


A complement system is a group of tiny immune system proteins that work together to assist other immune system components in their fight against pathogens.

There has been research done on Brittany Spaniels that reveals they are born without the complement protein C3.

These canines suffered from recurring bacterial illnesses, most notably skin disorders and pneumonia.

Even though complement is necessary for activating certain types of white blood cells, bacterial infections do not always develop in individuals who are deficient in complement.

This is because there are other ways to activate the system even if one pathway is blocked, so even if the complement is lacking, the system can still be activated.

A blood test that reveals decreased amounts of protein can serve as the basis for a diagnosis.

People have been found to be born with an inhibitor of the complement protein C1 deficiency, but dogs only sometimes display this unusual genetic anomaly.

This can result in complement activation that is out of control and inflammation. Dogs who are affected will experience recurrent episodes of face edema.

There is currently no treatment that is tailored specifically to complement deficits. Infectious diseases can be prevented and treated using vaccinations and antibiotics, respectively.

Animals used in breeding programs need to be carefully selected to avoid the disease being passed on to subsequent generations. This is true for all inherited disorders.

 

Immunoglobulin (Antibody) Deficiency.


Insufficient production of antibodies within the body is the root cause of immunoglobulin (antibody) deficiency (immunoglobulins).

This impairment may be congenital (existing at birth) or acquired (induced by other disorders) (present at birth).

Beagles, German Shepherds, and Chinese Shar-Peis have been shown to have congenital deficiencies of immunoglobulin (immunoglobulin A, or IgA), resulting in respiratory infections and digestive system issues, skin illness, or allergic reactions.

Puppies that do not obtain an adequate amount of antibodies from their mothers are more likely to develop acquired deficits.

In older animals, the problem is frequently caused by a reduction in the synthesis of antibodies.

A lack of immunoglobulin can develop as a complication of any condition that interferes with the body’s natural ability to produce antibodies.

For instance, certain malignancies, such as lymphosarcoma and plasma cell myeloma lead to aberrant antibodies, decreasing the production of normal antibodies.

Canine distemper and parvovirus are two examples of viruses that can cause damage to the tissues that are responsible for the production of antibody-forming cells.

Some young dogs also suffer from a temporary antibody shortage that puts them at a higher risk for respiratory infections between the ages of one and six months.

However, these dogs show signs of improvement by the time they reach the age of eight months.

Combined Immunodeficiency Disease (CID).


In combined immunodeficiency illness, there is a failure in cell-mediated immunity and the generation of antibodies.

Because of these abnormalities, the body cannot defend itself against intruders from outside.

Basset Hounds, Toy Poodles, Rottweilers, and mixed-breed puppies have all been carriers of the disease.

Dogs affected by this condition are healthy for the first few months of their lives, but as they become older, they develop an increased risk of bacterial illnesses because the antibodies they obtained during nursing begin to wear off.

There is now no treatment for this condition, and the prognosis for the future is not good.

 

Selective Immunodeficiencies.


Canine parvovirus infections in Rottweiler puppies are more likely to be severe and ultimately deadly than in other breeds of puppies.

Their resistance to other diseases is basically normal, and the cause of this selective immunodeficiency is a mystery to medical science.

Certain breeds of dogs are exposed or predisposed to developing both localized and systemic fungal infections.

Long-nosed breeds, particularly German Shepherds and shepherd mixes, have a greater risk of developing fungal infections in their nasal passages.

Long-nosed breeds also have a greater risk of developing ear infections.

Aspergillosis, a form of fungal illness that can affect the whole body, is nearly never observed in any other dog breed than German Shepherds.

Infection of the kidneys, bones, and discs located in between the vertebrae of the spinal cord are all symptoms of this condition.

 

Viruses Responsible For Immune Deficiencies.


A variety of viruses could be responsible for developing these kinds of diseases in animals.

Lymphocytes, a type of white blood cell, are destroyed when dogs are infected with the distemper virus.

The infection is linked to a gradual decrease in levels of antibodies and an increased vulnerability to bacterial infections that are usually controlled by the immune system.

This is because the infection suppresses the immune system.

An infection with the parvovirus in a dog results in a significant reduction in the number of white blood cells in the dog’s blood and a diminished immune response to bacterial and fungal illnesses.
