Abstract:

In summary, the Babesiosis, also well-knowm as piroplasmosis, is caused by two protozoarios intraeritrocitos species which are babesia bovis and babesia bigemina. The Babesiosis bovina is a illness transmitted by ticks of the gender Boophilus, and it is endemic in subtropical regions. It is characterized to present fever and hemolisis intravascular, causing a syndrome of anemia. This is one of the most important illnesses from the economic point of view of the tropical cattle raising.
