Feline Leukemia is also one of the infectious diseases of cats, and the infection rate of this disease is directly related to the density of cat feeding. Due to its high infectivity, as long as one cat is infected with this disease, then other cats are likely to be infected, so we must prevent this in advance.
Symptoms & Signs of Feline Leukemia
Feline Leukemia Virus(FeLV) infected cats will show related clinical diseases when they develop into continuous infection. Most of the infected cats will die within four years. The clinical signs associated with FeLV infection are mainly related to hematopoietic system infections, and bone marrow infections will be serious It affects the development of lymphocytes and bone marrow cells, which in turn leads to cell proliferation (tumor neoplasia) or suppression. In addition, FeLV infection is often accompanied by reproductive disorders.
1. Neoplasia: FeLV can cause neoplasia in lymphoid tissue or bone marrow tissue, and the most common malignant tumor of the hematopoietic system in cats is lymphosarcoma, accounting for about 90% of all hematopoietic tumors and one-third of all cat neoplasm cases. Therefore, most cases of cat’s lymphosarcoma are related to FeLV infection. Lymphosarcoma can also be found in the kidneys, nose, eyes, central nervous system, and skin.
2. Anemia: Compared with other breeds of animals, cat anemia is more common, and FeLV may be the most important factor causing this condition.
3. Immunosuppression: FeLV-infected cats with persistent infections are particularly susceptible to viral, bacterial, and fungal infections of the respiratory and gastrointestinal tracts. Such cats usually show weight loss and poor long-term health, or persistent fever; although Stomatitis and gingivitis in old cats are mostly related to FIV infection, but FeLV may still be accompanied by stomatitis and gingivitis; Little cats with persistent abscesses or slow wound healing may also because of the immunosuppression caused by FeLV; There are also reports that FeLV-infected cats may develop enteritis similar to panleucopenia (feline plague).
4. Reproductive disorders: FeLV infection is one of the common factors of reproductive disorders in cats. Female cats infected with FeLV usually have fetal reabsorption within 3 to 5 weeks of pregnancy, which may be accompanied by vaginal discharge, and most of them The infected female cat usually has a normal pregnancy before, but the exact mechanism of early fetal death is not yet known. It is generally believed that it may be related to placenta or endometritis. Even if the fetus can survive luckily to delivery Cats will continue to be infected and weakened by FeLV, so FeLV may be one of the possible causes of fading kitten syndrome.
Feline Leukemia Disease Feature
The source of infection of this disease is a sick cat. The cat’s saliva, feces, urine, milk, and nasal secretions all contain viruses, which are transmitted to healthy cats through the respiratory tract and digestive tract. It can also be passed to the embryo through the placenta of the sick cat.
Young cats are more susceptible to infection than adult cats, and there is no gender difference in breeds. Cats in the incubation period can excrete high concentrations of virus through saliva. Viruses that enter the cat can replicate in the trachea, nasal cavity, oral epithelial cells, and salivary gland epithelial cells.
Treatment of Feline Leukemia
There is no effective treatment for this disease. You can try antibiotics to prevent secondary bacterial infections, supply nutrition by infusion and correct dehydration, and administer antiviral drugs. There is no effective vaccine for this disease. Serological therapy and radiotherapy can be used to inhibit tumor growth.
