Genus Piroplasma refers to a group of parasitic protozoans that infect the red blood cells of mammals. Other synonyms for this genus include Babesia, Theileria, and Cytauxzoon. Each of these groups also includes species of blood parasites that cause similar symptoms and health issues in their hosts. Babesia is commonly found in cattle, dogs, and other domestic animals. Theileria can infect both domestic and wild animals, while Cytauxzoon primarily infects wild cats in North and South America. These parasites are spread through tick bites and can cause anemia, fever, and other severe health issues if left untreated.
