Babesiosis

Canine babesiosis is a tick-borne disease caused by a protozoan blood parasite. The cause of the disease is an organism of the genus Babesia. There are two species of Babesia that can cause disease in the United States: Babesia canis and Babesia gibsoni.

The organism is spread to dogs through the bite of a tick and can infect dogs of all ages, although most infected dogs are less than three years old. In the United States, there is a peak incidence occurring between March and October. Greyhounds have a higher incidence of the disease than other breeds.

Babesiosis mainly affects red blood cells, causing anemia, although many organ systems can be involved, and many complications can arise; disease can be mild, or can be fatal.
