Parasitic Infection of the Blood Vessels in Cats
Cytauxzoonosis in Cats
Cytauxzoonosis is a parasitic infection of the blood vessels of the cat's lungs, liver, spleen, kidneys, and brain. The protozoan parasite Cytauxzoon felis can also infect bone marrow and the developmental stages of red blood cells, thereby causing anemia. An uncommon disease, cytauxzoonosis typically affects feral and domestic cats in the south-central and southeastern United States.
Symptoms and Types
Symptoms associated with cytauxzoonosis are usually severe, including:
The parasite is transmitted from the bite of an infected ixodid tick, which are known to roam in areas shared by reservoir hosts like the bobcat and Florida panther.
You will need to give a thorough history of your cat’s health to your veterinarian, including the onset and nature of the symptoms. He or she will then perform a complete physical examination as well as a complete blood count, biochemistry profile, urinalysis, and electrolyte panel.
The bloodwork will typically reflect changes due to severe anemia caused by a combination of red cell membrane destruction (hemolysis) and hemorrhaging. In addition, the blood smear may reveal the erythrocytic form of the parasite, which is one to two micrometres in diameter, inside the red blood cells.
Splenic and bone marrow aspirate, meanwhile, are best used to identify to demonstrate the extraerythrocytic form of the parasite.
A condition in which the skin becomes yellow in color as do the mucous membranes; this is due to excess amounts of bilirubin.
A condition in which the spleen becomes enlarged
An in-depth examination of the properties of urine; used to determine the presence or absence of illness
The introduction of an animal to an organism in order to create a slight disease to induce immunity
An enlargement of the liver to an abnormal size
a) inhaling b) getting out fluid or gas by the act of sucking.
The breakdown of blood cells
A condition of the blood in which normal red blood cell counts or hemoglobin are lacking.
