Babesia bigemina is a species of alveolates belonging to the phylum Apicomplexa and the family Babesiidae, a type of protozoan parasite. In cattle, it causes babesiosis , also called "Texas fever". Its length is 4–5 μm and its width is 2–3 μm.
Babesia species show host specificity, allowing many different subspecies of Babesia to emerge, each infecting a different kind of vertebrate organism. [15] While B. bovis and Babesia bigemina prefer to infect cattle in tropical environments, they can infect other animals, such as the white-tailed deer . [ 15 ]
Babesia canis and B. bigemina are "large Babesia species" that form paired merozoites in the erythrocytes, commonly described as resembling "two pears hanging together", rather than the "Maltese cross" of the "small Babesia species". Their merozoites are around twice the size of small ones. [citation needed]
R. microplus serves as a vector for numerous pathogens, most notably Babesia bigemina and B. bovis. B. bigemina and B. bovis are responsible for bovine babesiosis which is ranked as the most economically important arthropod-transmitted illness in cattle. Bovine babesiosis is characterized by anemia, fever, and potentially multiple organ failure ...
Babesia bovis protozoa are transmitted by R. microplus and cause babesiosis or redwater fever in cattle throughout the tropics and subtropics wherever this boophilid species occurs. The less pathogenic Ba. bigemina is transmitted by R. microplus and R. decoloratorus. Development of Babesia in the tick

Organisms whose life cycles rely on this process include Theileria, Babesia, [4] Plasmodium, [5] and Toxoplasma gondii. Sporogony is a type of sexual and asexual reproduction. It involves karyogamy, the formation of a zygote, which is followed by meiosis and multiple fission. This results in the production of sporozoites.
