Babesia bovis
A species of protozoa that is a cause of bovine babesiosis. Ticks of the genera Boophilus, Rhipicephalus, and IXODES are the chief vectors.
Babesia
Babesiosis
A group of tick-borne diseases of mammals including ZOONOSES in humans. They are caused by protozoa of the genus BABESIA, which parasitize erythrocytes, producing hemolysis. In the U.S., the organism's natural host is mice and transmission is by the deer tick IXODES SCAPULARIS.
Babesia microti
A species of protozoa infecting humans via the intermediate tick vector IXODES scapularis. The other hosts are the mouse PEROMYSCUS leucopus and meadow vole MICROTUS pennsylvanicus, which are fed on by the tick. Other primates can be experimentally infected with Babesia microti.
Cattle Diseases
Diseases of domestic cattle of the genus Bos. It includes diseases of cows, yaks, and zebus.
Rhipicephalus
A genus of TICKS, in the family IXODIDAE, widespread in Africa. Members of the genus include many important vectors of animal and human pathogens.
Theileria
A genus of tick-borne protozoa parasitic in the lymphocytes, erythrocytes, and endothelial cells of mammals. Its organisms multiply asexually and then invade erythrocytes, where they undergo no further reproduction until ingested by a transmitting tick.
Cattle
Antigens, Protozoan
Streptococcus bovis
Anaplasmosis
A disease of cattle caused by parasitization of the red blood cells by bacteria of the genus ANAPLASMA.
Mycoplasma bovis
A species of gram-negative bacteria causing MASTITIS; ARTHRITIS; and RESPIRATORY TRACT DISEASES in CATTLE.
Ticks
Blood-sucking acarid parasites of the order Ixodida comprising two families: the softbacked ticks (ARGASIDAE) and hardbacked ticks (IXODIDAE). Ticks are larger than their relatives, the MITES. They penetrate the skin of their host by means of highly specialized, hooked mouth parts and feed on its blood. Ticks attack all groups of terrestrial vertebrates. In humans they are responsible for many TICK-BORNE DISEASES, including the transmission of ROCKY MOUNTAIN SPOTTED FEVER; TULAREMIA; BABESIOSIS; AFRICAN SWINE FEVER; and RELAPSING FEVER.

Protozoan Vaccines
Theileriasis
Erythrocytes
Red blood cells. Mature erythrocytes are non-nucleated, biconcave disks containing HEMOGLOBIN whose function is to transport OXYGEN.
Merozoite Surface Protein 1
Moraxella (Moraxella) bovis
A species of gram-negative, aerobic bacteria that is most frequently isolated from bovine eyes in cases of infectious keratoconjunctivitis (KERATOCONJUNCTIVITIS, INFECTIOUS), but also occurs in unaffected eyes and the nasal cavity of cattle.
