Feline Infectious Anemia
Feline infectious anemia (FIA) is most common in male cats one to three years of age. It is caused by a rickettsial microorganism called Hemobartonella felis. It attaches to the surface of red blood cells and destroys these cells, producing a hemolytic anemia.
The exact method of transmission of this disease is not known. IT may be transferred from one cat to another by the bite of blood-sucking insects such as a flea or by the bite of infected cat. Unborn kittens may be infected through the placenta if the mother harbors the microorganisms. Such kittens may be stillborn; or they may die within a few hours.
Thirty percent of untreated cats die from this infection. Cats infected with feline infectious peritonitis or
feline leukemia are less likely to recover from feline infectious anemia.
SYMPTOMS
A cat with FIA has fever (103°F to 106°F), appears weak and lethargic and may show signs of anemia (pale gums). Jaundice can occur due to rapid destruction of red blood cells. Cats that recover become carriers and can suffer recurrent bouts of infection or chronic anemia for years.
DIAGNOSIS
Any cat with anemia can be suspected of having feline infectious anemia. Your veterinarian can make the diagnosis by finding hemobartonella organisms under a microscope on a smear of blood taken from the cat. At times the organisms disappear from the circulation and may not be seen. Accordingly, more than one blood smear might be required to make the diagnosis.
TREATMENT
Oral tetracycline is given for two to three weeks. The cat's general condition should improve with appropriate nutritional support. Blood transfusions are indicated if the anemia is severe. Assiciated illnesses should be treated. Steroids are sometimes prescribed if there is an autoimmune component to the anemia.
Go Pets America recommends seeking the advice of your local veterinarian for the most appropriate vaccination program and for the diagnosis and treatment of your pet's health problems. For vaccination requirements please contact your state and local licensing authorities.
