What is Parasitic Blood Infection in Cats?

The kinds of parasites, which infect the cat might also come in an extensive range, from a single-celled protozoa through a more complicated forms of bacteria.

Hemotrophic mycoplasmosis or parasitic blood infection in cats is actually an infection of red blood cells by the mycoplasma. Further, the mycoplasma bacteria are actually the most common cause of pneumonia and urinary tract infections. They’re a class of bacterial parasite, which belongs to the Mollicutes order. Also, the parasites lack real cell walls and are capable of surviving without oxygen, thus making them resistant to the antibiotics and hence a much greater challenge in detecting and treating.

Moreover, the parasitic blood infections in cats include a range of conditions wherein parasitic organisms may invade the blood system of the cat. The conditions may range in severity and origin. Some may lead to mild sickness, while the others might cause austere anemia or even bereavement.


There are different parasitic blood infections, which are able to infect the cat. Below are some of the most common particular conditions and the parasitic cause:

  • Changas’ Disease. This is due to an infection by the trypanosomes, biting insects may transmit this condition in between domestic cats and wild animals. This particular condition might also be communicated to humans for the cats.
  • Hepatozoonosis. This is a tick-bone disease, which is transmitted through the brown dog tick. The tick may become infected when feeding on the infected host, yet cats may just acquire the condition, by way of eating the tick, not through being bitten.
  • Feline Infectious Anemia. Also known as hemobartonellosis, a common parasitic blood infection in cats is due to a kind of bacteria, which enters the bloodstream, through blood-sucking insects like ticks and fleas, and may also be transmitted through fighting or scratches.
  • Cytauxzoonosis. This is due to a parasite by the similar name, this condition may naturally occur in the wild cats in North America. Also, this spread to domestic cats through tick bite.


Even though the majority of the parasitic blood infections in cats are spread through biting insects, there are a range of some other ways that these conditions might be transmitted. Moreover, cats or wild cats allowed in interacting with feral or wild cats, might especially be at risk. The common causes include:

  • Blood transfusion
  • Spread from infected from mother cat to kittens
  • Scratches
  • Spread of blood via fighting with some other cats
  • Spread of blood via mating

You also need to provide thorough info on the diet of the cat, whether it’s an outdoor or indoor cat, as well as whether it’s recently come in contact with any other domesticated or wild animals. You need to discuss as well whether your cat is on whatever tick and flea control regimen, since this may possibly help in narrowing down the organism, which causes the parasitic blood infection.

Treatment for Parasitic Blood Infection in Cats

The treatment for parasitic blood infection in cats might be two-fold. First, the vet may stabilize the cat and deal with some immediate lethal symptoms. This might include intravenous fluids, as well as medicated baths, in order to get rid of any ticks or fleas, and in some austere cases, blood infusion, in order to counteract austere anemia.

In addition, the next step may be addressing the parasite itself, and the treatment may vary on the exact organism that’s being identified through diagnostic tests. Further, it can be important for the vet in identifying the real kind of parasitic infection, as the choice of medication may greatly vary from a parasite to another. In the case of most bacteria, antibiotics might be a preferred treatment plan.
