Babesiosis in Ruminants (Piroplasmosis, Texas fever, redwater, tick fever)

Babesiosis is caused by intraerythrocytic protozoan parasites of the genus Babesia . The disease, which is transmitted by ticks, affects a wide range of domestic and wild animals and occasionally humans. While the major economic impact of babesiosis is on the cattle industry, infections in other domestic animals, including horses, sheep, goats, pigs, and dogs, assume varying degrees of importance throughout the world. Two important species in cattle :

B bigemina and B bovis

are widespread in tropical and subtropical areas and are the focus of this discussion. However, because there are many common features of the diseases caused by different Babesia , much of this information can be applied to other species.
