Circular Tecnica, 31).  aTick fever is a general name for a disease caused by both or either haemoparasites Babesia and Anaplasma. Cattle tick Boophilus microplus is the vector of the disease although anaplasmosis can also be transmitted by blood sucking insects. In most regions of Brazil, B. microplus can occur throughout the year because of suitable climate conditions. In the brazilian savannah region there are two or three cattle tick generations per year with a infestation peak in october. The increasing use of cultivated pastures and crosses with tick-susceptible european breeds has decreased resistance of zebu cattle in this region and control measures are suggested. Total control of B. microplus, howecer, can decrease cattle imunity and favours the occurence of tick fever. Laboratory texts such as blood smears, microhaematocrit, and sorology are required for a reliable diagnosis of the disease. Tick fever can be avoid by prophylactic measures (prmunition, vaccination or chemoprophylaxix). Therapeutic treatment is based on the use of drugs such as imidocarb (babesiosis) and tetracycline (anaplasmosis).  aanaplasmosis  aanimal diseases  ababesiosis  aBoophilus Microplus  aBovino  aCarrapato  aCerrado  aDoença  aDoença Animal  aTransmissão de Doença  aTristeza Parasitaria  aBrazilian savannas  aCatle tick  aCattle tick  aDisease  aDiseases
