Diseas

 
 


FeLV, FIV

Feline leukemia virus (FeLV), a retrovirus, so named because of the way it behaves within infected cells. All retroviruses, including feline immunodeficiency virus (FIV) and human immunodeficiency virus (HIV), produce an enzyme, reverse transcriptase, which permits them to insert copies of their own genetic material into that of the cells they have infected. Although related, FeLV and FIV differ in many ways, including their shape: FeLV is more circular while FIV is elongated. The two viruses are also quite different genetically, and their protein consituents are dissimlar in size and composition. Although many of the diseases caused by FeLV and FIV are similar, the specific ways in which they are caused differs.

HCM
HCM is a disease that causes thickening of the heart muscle resulting in poor relaxing and filling ability. As the heart’s pumping chamber (ventricle) becomes progressively thicker, less blood can enter the chamber; thus, less blood is ejected out to the body. The cause of HCM is unknown, although certain breeds of cats appear to be predisposed. Middle-aged male cats may be more commonly affected. Sometimes heart muscle thickening similar to HCM can develop secondary to other disorders such as hyperthyroidism (elevated thyroid hormone) and systemic hypertension (elevated blood pressure). Blood pressure measurement and, in cats over five years of age, a blood thyroid hormone test should be done to exclude these secondary causes when cardiac hypertrophy (thickening) is diagnosed. An animal can be free and has in that situation two healthy alleles. When used in breeding this animal will not become ill due to the disease. It cannot spread the disease in the population. An animal can be carrier and has in that situation one healthy and one disease allele. When used in breeding 50 percent of the offspring will receive the disease allele. Carriers will not become ill! An animal can be affected and has in that situation two disease alleles. When used in breeding all offspring will also receive the disease allele. Affected will become ill.

PKD
Autosomal Polycystic Kidney Disease (PKD) is a progressive, inherited condition which causes multiple fluid filled cysts on the kidneys of Persians/Exotic/British Sorthair cats & breeds with Persians/Exotics/British Sorthair in their lines. Cysts are present from birth, but start out small, slowly increasing in size. Cysts can range from very small to several centimetres in diameter. The increasing size of the cysts damage the normal kidney tissue, eventually causing kidney failure. The number of cysts & the speed & size in which they grow varies from cat to cat. The average age of kidney failure in cats with PKD is 7 years, but some cats will suffer from kidney failure at an earlier age & some cats much later, and in fact succumb to something other than PKD.

SMA
Spinal Muscular Atrophy (SMA) is strongly resembling other muscular diseases in humans and other species. The disease is characterized by weakness and atrophy (degeneration) of muscles. Symptoms will develop at a young age. Within a few hours to a maximum of several weeks after birth, the characteristics that go with these genetic effects will become visible. Normally the result can be expected within 10 working days. This turn-around-time starts when both the sample and the fully filled-out and signed submission form have been received. The disease is present in muscle. Depending on the effect, degeneration of muscle may take place. Alternatively, recovery following exercise may be deterioratedAn animal can be free and has in that situation two healthy alleles. When used in breeding this animal will not become ill due to the disease. It cannot spread the disease in the population. An animal can be carrier and has in that situation one healthy and one disease allele. When used in breeding 50 percent of the offspring will receive the disease allele. Carriers will not become ill. An animal can be affected and has in that situation two disease alleles. When used in breeding all offspring will also receive the disease allele. Affected will become ill.
