Common names of the disease that Babesia microti causes are Texas cattle fever, redwater fever, tick fever, and Nantucket fever. [7] The disease it causes in humans, babesiosis, is also called piroplasmosis.

Babesia bovis is an Apicomplexan single-celled parasite of cattle which occasionally infects humans. The disease it and other members of the genus Babesia cause is a hemolytic anemia known as babesiosis and colloquially called Texas cattle fever, redwater or piroplasmosis.
Cattle fever ticks (Rhipicephalus (Boophilus) annulatus and R. (B.) microplus) are the most dangerous cattle ectoparasites in the United States. These ticks have been a threat to American agriculture for generations because they spread the disease bovine babesiosis, commonly called cattle fever.

Half of all children and a quarter of previously healthy adults with Babesia infection are asymptomatic. When people do develop symptoms, the most common are fever and hemolytic anemia, symptoms that are similar to those of malaria. People with symptoms usually become ill 1 to 4 weeks after the bite, or 1 to 9 weeks after transfusion of contaminate...
Babesia species are in the phylum Apicomplexa, which also has the protozoan parasites that cause malaria, toxoplasmosis, and cryptosporidiosis. Four clades of Babesia species infect humans. The main species in each clade are:[citation needed] 1. B. microti(< 3 μm) 2. B. duncani 3. B. divergens (cattle parasite seen mostly in Europe) and B. venatoru...
Babesia parasites reproduce in red blood cells, where they can be seen as cross-shaped inclusions (four merozoites asexually budding, but attached together forming a structure looking like a "Maltese cross")and cause hemolytic anemia, quite similar to malaria. Unlike the Plasmodium parasites that cause malaria, Babesiaspecies almost never exhibit a...
Only specialized laboratories can adequately diagnose Babesia infection in humans, so Babesia infections are considered highly under-reported. It develops in patients who live in or travel to an endemic area or receive a contaminated blood transfusion within the preceding 9 weeks, so this aspect of the medical history is vital. Babesiosis may be su...
Treatment of asymptomatic carriers should be considered if parasites are still detected after 3 months. In mild-to-moderate babesiosis, the treatment of choice is a combination of atovaquone and azithromycin. This regimen is preferred to clindamycin and quinine because it has fewer side effects. The standard course is 7 to 10 days, but this is exte...
Babesiosis is a vector-borne illness usually transmitted by Ixodes scapularis ticks. B. microti uses the same tick vector as Lyme disease, and may occur in conjunction with Lyme. The organism can also be transmitted by blood transfusion. Ticks of domestic animals, especially Rhipicephalus (Boophilus) microplus and R. (B.) decoloratus transmit sever...
The disease is named for the genus of the causative organism, which was named after the Romanian bacteriologist Victor Babeș. In 1888, Victor Babeș identified the microorganisms in red blood cells as the cause of febrile hemoglobinuria in cattle. In 1893, Theobald Smith and Frederick Kilborne discovered that a tick was the vector for transmission i...
Veterinary treatment of babesiosis does not normally use antibiotics. In livestock and animals, diminazen (Berenil), imidocarb, or trypan blue would be the drugs of choice for treatment of B. canis rossi (dogs in Africa), B. bovis, and B. bigemina (cattle in Southern Africa). In acute cases in cattle, blood transfusion may be carried out. A vaccine...

Bovine babesiosis is a tick-borne parasitic disease that results in significant morbidity and mortality in cattle. The economic losses can be considerable, especially when animals with no immunity are moved into an endemic area.
What is a cattle fever tick? Cattle fever ticks, known scientifically as Rhipicephalus (formerly Boophilus) annulatus and R. microplus, are a significant threat to the United States cattle industry. These ticks are capable of carrying the protozoa, or microscopic parasites, Babesia bovis or B. bigemina, commonly known as cattle fever. Cattle ...
