Leukemia in cats – Symptoms, treatment and causes of infection

Feline leukemia is a disease caused by FLVe virus (feline leukemia virus) that causes a depression of the immune system in the animal. The virus affects the white blood cells of your immune system, making the animal less defensive and more at risk of infection and other complications.

This disease is found in cats around the world, causing even the death of the animal. It is not transmitted to human beings. Keep reading this article to know everything about leukemia in cats, symptoms, treatment and causes of infection.

Causes of contagious feline leukemia

It is transmitted between cats through body fluids (saliva, blood, feces, urine, nasal secretions, etc.) or during pregnancy and lactation.

It is typical of cats that live in the outside or street cats who live in a group or in colonies. When the virus comes into contact with the animal’s immune system, three situations can occur:

  • The cat is immune since it has created antibodies that can cope with the virus. You may have symptoms for a few weeks but then you will stop having them.
  • The virus enters the blood and saliva, damaging the immune system and causing leukemia. The animal is more likely to be infected with other diseases. They do not live beyond 2 or 3 years.
  • The virus is eliminated from the blood and saliva but remains latent in the bone marrow. Although the virus can be reactivated, it will most likely not affect our cat.

Symptoms of leukemia in cats

  • Swelling of the lymph nodes

Diagnosis

In addition to taking into account the symptoms, you must confirm if the cat really suffers from leukemia, you can do the following tests:

  • ELISA (Enzyme-linked immunosorbent assay): This test is typical of veterinary clinics. A blood sample is collected from the cat and detected if there is the presence of the antigen, or initial stages of the infection. After several weeks it will be confirmed if it is positive, since it is not known whether the infection is temporary or permanent.
  • PCR (polymerase chain reaction): detects the DNA of the virus in the affected cells either in blood samples, as in other tissues. Although it can detect latent infections, it is not as available unlike ELISA.
  • IFA (direct immunofluorescence): it is not useful to detect initial stages but it serves to confirm ELISA positives. Detects the presence of the antigen in infected cells.

Treatment of leukemia in cats
